MOA03	Status Report on GANIL and Upgrade of SPIRAL1	cyclotron, experiment, ion-source, ECR	9
	O. Kamalou, P. Delahaye, M. Dubois, A. Savalle GANIL, Caen, France
	The GANIL facility (Grand Accélérateur National d’Ions Lourds) at Caen is dedicated for acceleration of heavy ion beams for nuclear physics, atomic physics, and radiobiology and material irradiation. Nowadays, an intense exotic beam is produced by the Isotope Separation On-Line method at the SPIRAL1 facility since 2001. New demands from the physics community motivated the upgrade of this facility in order to extend the range of post-accelerated radioactive ions. A 2 MEuro project allowed the profound modification of the facility and the commissioning was achieved in 2017. The status of this facility and the last results will be presented. The review of the cyclotron operation from 2001 to 2019 will be presented as well.

Van Niekerk, P.A. van Schalkwyk iThemba LABS, Somerset West, South Africa
	With the termination of the neutron and proton therapy programs at iThemba LABS, the use of the Separated Sector Cyclotron (SSC) has now shifted to nuclear physics research with both stable and radioactive ion beams, as well as biomedical research. A dedicated isotope production facility with a commercial 70 MeV H-minus cyclotron has been approved and both the cyclotron and isotope production target stations will be housed in the vaults that were previously used for the therapy programs. The status of this new facility will be reported. In the future the SSC will mostly be used for nuclear physics research, as well as the production of isotopes that cannot be produced with the 70 MeV H-minus cyclotron. At present the production of the alpha-emitting radionuclide Astatine (211At) with a 28 MeV alpha beam is being investigated. Progress with the construction of a facility for production of radioactive beams will be discussed. There will also be reports on development work on the ECR ion sources and progress with implementation of an EPICS control system.

MOP010	A 50 MeV Proton Beam Line Design	proton, cyclotron, quadrupole, radiation	45
	S.M. Wei, S. An, L.L. Guan, Y.L. Lv CIAE, Beijing, People’s Republic of China
	The cyclotron Center at the China Institute of Atomic Energy (CIAE) is now developing a medium-energy proton irradiation device that provides a proton beam with an energy range of 30 MeV to 50 MeV to simulate a space proton radiation environment, which has a significant impact on spacecraft. A beam transport line is designed for irradiation effect study based on the 50 MeV compact cyclotron, which requires continuous adjustment of the beam energy and the beam spot on the target requires high uniformity. The proton beam extracted from the cyclotron is adjusted to the energy required by using the degrader, then the proton beam is bended and focused. In order to obtain uniform large-diameter beam spot on the target, a wobbling magnet is installed on the beam line to uniformly sweep the proton beam on the target and finally obtain the proton beam with energy of 30 MeV - 50 MeV, current of 10 uA and beam spot of 20 cm * 20 cm on the target.

MOP022	Project of a Novel Multi-Orbital Beam Bunching and Extraction from the U-120M Cyclotron	cyclotron, neutron, extraction, bunching	80
	M. Čihák, R. Běhal, P. Krist, T. Matlocha, J. Stursa, V. Zach NPI, Řež near Prague, Czech Republic
	We introduce the bunching system for a time structure control of the U-120M cyclotron beam. The system is based on a unique pulsed vertical deflection of the selected final orbits of the internal accelerated beam of the H⁻ ions to an extractor-stripper (a thin carbon foil positioned below the cyclotron median plane). A set of home-made programs have been developed for simulations and parameters determination of the system. Results of some simulations (i.e. dimensions of the deflection system, parameters of the pulsed high voltage power supply, position of the stripper, beam trajectories, beam parameters, beam losses, Be target position etc.) are presented. The system will be used for fast neutron generation and consequently for spectrometric measurement of neutron energy by the time of flight (ToF) method. The system will provide beam bunch interval up to 1000 ns range of a defined beam time structure (up to beam bunch period to beam bunch width ratio min 100).

TUA02	Novel Irradiation Methods for Theranostic Radioisotope Production With Solid Targets at the Bern Medical Cyclotron	cyclotron, detector, radiation, proton	127
	S. Braccini LHEP, Bern, Switzerland C. Belver-Aguilar, T.S. Carzaniga, G. Dellepiane, P. Haeffner, P. Scampoli AEC, Bern, Switzerland P. Scampoli Naples University Federico II, Napoli, Italy
	The production of medical radioisotopes for theranostics is essential for the development of personalized nuclear medicine. Among them, radiometals can be used to label proteins and peptides and their supply in quantity and quality for clinical applications represents a challenge. A research program is ongoing at the Bern medical cyclotron, where a solid target station with a pneumatic delivery system is in operation. To bombard isotope-enriched materials in form of compressed powders, a specific target coin was realized. To assess the activity at EoB, a system based on a CZT detector was developed. For an optimized production yield with the required radio nuclide purity, precise knowledge of the cross-sections and of the beam energy is crucial. Specific methods were developed to assess these quantities. To further enhance the capabilities of solid target stations at medical cyclotrons, a novel irradiation system based on an ultra-compact ~50 cm long beam line and a two-dimensional beam monitoring detector is under development to bombard targets down to few mg and few mm diameter. The first results on the production of Ga-68, Cu-64, Sc-43, Sc-44 and Sc-47 are presented.

	Paul Scherrer Institute runs a High Intensity Proton Accelerator (HIPA) facility, where a maximum of 100 µA protons is gleaned from high intensity 72 MeV protons from Injector 2, a separated sector cyclotron, into the IP2 target station. These protons irradiate various targets towards the production of exotic radionuclides intended for medical purposes. Many radiometals in use today are for the diagnosis of disease, with the most popular means of detection being Positron Emission Tomography. These positron emitters are easily produced at low proton energies using medical cyclotrons, however, development at these facilities are lacking. The 72 MeV proton beam is degraded at IP2 using niobium to provide the desired energy to irradiate targets to produce the likes of 44Sc, 43Sc, 64Cu and 165Er,,*. Once developed, these proofs-of-principle are then put into practice at partner facilities. Target holders and degraders require development to optimize irradiation conditions and target cooling. Various options are explored, with pros and cons taken into consideration based on calculations and simulations. v/d Meulen et al., Nucl Med. Biol. (2015) 42: 745 Domnanich et al., EJNMMI Radiopharm.

	M. Kreller, T. Knieß HZDR, Dresden, Germany S. Preusche Helmholtz-Zentrum Dresden-Rossendorf, Dresden, Germany
	The new Center for Radiopharmaceutical Cancer Research was established at Helmholtz-Zentrum Dresden-Rossendorf e. V. to centralize the main units: a high current proton cyclotron, a radiopharmaceutical production – GMP unit including quality control, laboratories for PET-radiochemistry, chemical and biochemical laboratories and laboratories for small animal imaging. The cyclotron TR-Flex was put into operation in 2017 and it is equipped with two extraction ports. Both are movable to adjust the proton energy in the range from 15 MeV up to 30 MeV. One extraction port is coupled with a combination magnet and two beam lines. A [123I]I-gas target station is installed at the first beam line and a four-port target selector at beamline two and at the second extraction port. Two [18F]F-water targets, a [18F]F2-gas target, a [11C]CH₄-gas target, a [11C]CO₂-gas target, a 30° and a 90° solid state target are mounted on the target selectors. In our contribution we report our experience of the new cyclotron during the first two operation years. Typical beam parameters and the reliability of the TR-FLEX are presented. Furthermore we describe the new home-built Radionuclide Distribution System.

	Quasi-monoenergetic neutron beams are typically produced at the iThemba LABS fast neutron beam facility by the 7Li(p, xn) or 9Be(p, xn) reactions. With the proton beams available from the separated sector cyclotron, the neutron energy range from about 30 MeV to 200 MeV can be covered almost continuously. The facility first became operational in the late 1980s. The fast neutron beam facility at iThemba LABS has been designated by the National Metrology Institute of South Africa (NMISA) as an entity responsible for providing traceability for the medium and high-energy neutron measurements in South Africa. As a result, the facility is undergoing a major upgrade and development in order for it to meet the requirements for a medium and high-energy neutron metrology facility. As part of the ongoing upgrade, Monte Carlo (MC) simulations aimed at benchmarking the experimental data are ongoing.

TUP016	New Centering Beam Monitor for High Power Proton Beam Rotating Target	experiment, proton, operation, cyclotron	189
	P.-A. Duperrex, P. Baumann, S. Joray, D.C. Kiselev, D. Laube, D. Reggiani PSI, Villigen PSI, Switzerland
	The high intensity proton accelerator (HIPA) at the Paul Scherrer Institut (PSI) delivers 590 MeV c.w. proton beam with currents of up to 2.4 mA, i.e. 1.4 MW beam power, For experiments of nuclear and material research the beam is directed to the 4 or 6 cm graphite 1 Hz rotating target (Target E). Centring the beam on the target is an important task for the operation and has safety issues in case of beam misalignment. Transmission monitoring has been the standard method to optimize the beam position on the target, though not very sensitive. A new method is currently being tested that provides a more sensitive off-axis detection. It is based on the detection of beam inten-sity modulation from the milled grooves at the target edge. This paper presents the concept and preliminary experimental results that can be obtained with this method.

TUP019	Recent Extensions of JULIC for HBS Investigations	neutron, experiment, cyclotron, proton	195
	O. Felden, N. Demary, N.-O. Fröhlich, R. Gebel, Y. Valdau FZJ, Jülich, Germany M. Rimmler JCNS, Jülich, Germany
	At the Forschungszentrum Jülich (FZJ) the energy variable cyclotron JULIC is used as injector of the Cooler Synchrotron (COSY) and for low to medium current irradiations of different types. Recently a new target station was set up and is mainly used for tests of new target materials, neutron target development and neutron yield investigations with high power proton or deuteron beam in perspective of a high brilliance accelerator based neutron source (HBS) with the Jülich Center for Neutron Science. The neutrons are produced exposing material targets or compounds to proton or deuterium particles of relative low final particle energy in the MeV range and will be optimized for neutron scattering to be realized at reasonable costs. Beside this, ToF-experiments are performed to investigate and optimize the pulsing structure for HBS. The target station is installed inside an experimental area offering space for complex detector and component setups for nuclear and neutron related experiments. But it is used for other purposes like electronic or detector tests and irradiation as well. This report briefly summarizes the history of JULIC and the activities for its future perspectives.

	The HZB cyclotron has been providing protons for eye-tumor treatment for more than 20 years. While it has been very successful using conventional dose rates (15-20 Gy/min), recent studies indicate that rapid irradiation with very high dose rates (FLASH) might be equally efficient against tumors but less harmful to healthy tissues. The flexible operation schemes of the HZB cyclotron can provide beams with variable intensities and time structures, covering a wide unexplored regime within the FLASH requirements (>40 Gy/s in <500 ms). This paper presents the results of the first FLASH beam production at HZB towards the establishment of an in-vivo clinical irradiation in the future.

TUP022	Status of a 70 MeV Cyclotron System for ISOL Driver of Rare Isotope Science Project in Korea	cyclotron, ISOL, vacuum, diagnostics	205
	J.-W. Kim, J. Kang, J.H. Kim, T.S. Shin IBS, Daejeon, Republic of Korea
	A 70 MeV H⁻ cyclotron commercially available for medical isotope production will be used as an ISOL driver for rare isotope science project in Korea. The cyclotron is scheduled to be installed in 2021 for beam commissioning in the following year. In fact the building to house the cyclotron is currently almost complete so that the cyclotron system newly contracted needs to fit into the existing building, which brings some challenges in equipment installation and adaptation to utilities. Two beam lines to transport high-current proton beams into ISOL targets have been designed and are described along with other issues associated with the interface of the ISOL system.

	Funding: This project was supported by the NSTIP Strategic Technologies Program in the Kingdom of Saudi Arabia, award no. 14-MAT-1233-20. This paper reports a method to reduce the beam energy of the CS-30 cyclotron from 26.5 up to 10 MeV using the internal target system in CS-30 cyclotrons for isotopes production. Irradiation of solid targets, in this type of cyclotrons, take place when the target is positioned horizontally inside the cyclotron tank. In its final position, the target plate interrupts the beam from completing its orbit and nuclear reactions take place. Calculations are made to determine the beam energy as a function of radius. Verification of the new method was achieved by producing pure Ga-68 at an energy level of 11.5 MeV. [1] Gordon, M. M., Calculation of isochronous fields for sector-focused cyclotrons, Part.

TUC01	Review and Current Status of the 70 MeV High Intensity Proton Cyclotron at Legnaro	cyclotron, operation, proton, MMI	248
	M. Maggiore, P. Antonini, A. Lombardi, L. Pranovi INFN/LNL, Legnaro (PD), Italy Z. Filipovski UI PET, Skopje, Republic of North Macedonia
	In 2017 the new cyclotron has been successfully commissioned and started the operation at Laboratori Nazionali di Legnaro (LNL) of INFN . The cyclotron is the proton driver foreseen for the Selective Production of Exotic Species (SPES) project, providing the high power beam for radioactive ion beams (RIBs) production by the ISOL technique. The SPES facility is today under construction and first low energy RIBs are expected to be available on 2021. The facility has been designed in order to exploit the versatility of the cyclotron in terms of wide range of energy and beam current extracted: 35-70 MeV energy and 20 nA - 500 µA of average current. Moreover, the possibility to extract at the same time two proton beams allows to share these both for experimental physics session and applications. In particular, at LNL a collaboration between private company and public institution will lead to a profitable synergy in R&D of new radioisotopes and the related production. In the session the results of the commissioning and the operation of cyclotron will be presented as well as the description of the SPES facility together with its potentiality in nuclear physics research and applications.

	The beam line for radionuclide production on the PSI Cyclotron Facility starts with an electrostatic beam splitter, which peels protons of a few tens of microampere from a beam around two milliampere. The peeled beam is then guided onto a target station for routine production of a variety of radionuclides [1]. Beam Delivery Simulation (BDSIM), a Geant4 based simulation tool, enables the simulation of not only beam transportation through optics elements like dipoles and quadrupoles, but also particle passage through components like collimator and degrader [2-3]. Furthermore, BDSIM facilitates user built elements with accompanying electromagnetic field, which is essential for the modeling of the first element of the beam line, the electrostatic beam splitter. With a model including all elements from beam splitter to target, BDSIM simulation delivers a better specification of the beam along the complete line, for example, beam profile, beam transmission, energy spectrum, as well as power deposit, which is of importance not only for present operation but also for further development.

	Funding: United States Department of Energy, Grant DE-FG02-93ER40773 The first test beams of radioactive ions produced by the ion-guide-on-line (IGOL) system coupled to the charge-breeding electron-cyclotron-resonance ion source (CB-ECRIS) have been accelerated to high energy by the Texas A&M K500 cyclotron. The radioactive ions were first produced by energetic protons, provided by the K150 cyclotron, impinging on foil targets. Low charge-state ions were then swept by a flow of helium gas into an rf-only sextupole ion guide (SPIG) which transports them into the plasma of the CB-ECRIS. The K500 cyclotron and beam-line transport were tuned with analog beam before tuning the radioactive beam.

The GANIL facility (Grand Accélérateur National d’Ions Lourds) at Caen is dedicated for acceleration of heavy ion beams for nuclear physics, atomic physics, and radiobiology and material irradiation. Nowadays, an intense exotic beam is produced by the Isotope Separation On-Line method at the SPIRAL1 facility since 2001. New demands from the physics community motivated the upgrade of this facility in order to extend the range of post-accelerated radioactive ions. A 2 MEuro project allowed the profound modification of the facility and the commissioning was achieved in 2017. The status of this facility and the last results will be presented. The review of the cyclotron operation from 2001 to 2019 will be presented as well.

With the termination of the neutron and proton therapy programs at iThemba LABS, the use of the Separated Sector Cyclotron (SSC) has now shifted to nuclear physics research with both stable and radioactive ion beams, as well as biomedical research. A dedicated isotope production facility with a commercial 70 MeV H-minus cyclotron has been approved and both the cyclotron and isotope production target stations will be housed in the vaults that were previously used for the therapy programs. The status of this new facility will be reported. In the future the SSC will mostly be used for nuclear physics research, as well as the production of isotopes that cannot be produced with the 70 MeV H-minus cyclotron. At present the production of the alpha-emitting radionuclide Astatine (211At) with a 28 MeV alpha beam is being investigated. Progress with the construction of a facility for production of radioactive beams will be discussed. There will also be reports on development work on the ECR ion sources and progress with implementation of an EPICS control system.

CIAE, Beijing, People’s Republic of China

The cyclotron Center at the China Institute of Atomic Energy (CIAE) is now developing a medium-energy proton irradiation device that provides a proton beam with an energy range of 30 MeV to 50 MeV to simulate a space proton radiation environment, which has a significant impact on spacecraft. A beam transport line is designed for irradiation effect study based on the 50 MeV compact cyclotron, which requires continuous adjustment of the beam energy and the beam spot on the target requires high uniformity. The proton beam extracted from the cyclotron is adjusted to the energy required by using the degrader, then the proton beam is bended and focused. In order to obtain uniform large-diameter beam spot on the target, a wobbling magnet is installed on the beam line to uniformly sweep the proton beam on the target and finally obtain the proton beam with energy of 30 MeV - 50 MeV, current of 10 uA and beam spot of 20 cm * 20 cm on the target.

We introduce the bunching system for a time structure control of the U-120M cyclotron beam. The system is based on a unique pulsed vertical deflection of the selected final orbits of the internal accelerated beam of the H⁻ ions to an extractor-stripper (a thin carbon foil positioned below the cyclotron median plane). A set of home-made programs have been developed for simulations and parameters determination of the system. Results of some simulations (i.e. dimensions of the deflection system, parameters of the pulsed high voltage power supply, position of the stripper, beam trajectories, beam parameters, beam losses, Be target position etc.) are presented. The system will be used for fast neutron generation and consequently for spectrometric measurement of neutron energy by the time of flight (ToF) method. The system will provide beam bunch interval up to 1000 ns range of a defined beam time structure (up to beam bunch period to beam bunch width ratio min 100).

The production of medical radioisotopes for theranostics is essential for the development of personalized nuclear medicine. Among them, radiometals can be used to label proteins and peptides and their supply in quantity and quality for clinical applications represents a challenge. A research program is ongoing at the Bern medical cyclotron, where a solid target station with a pneumatic delivery system is in operation. To bombard isotope-enriched materials in form of compressed powders, a specific target coin was realized. To assess the activity at EoB, a system based on a CZT detector was developed. For an optimized production yield with the required radio nuclide purity, precise knowledge of the cross-sections and of the beam energy is crucial. Specific methods were developed to assess these quantities. To further enhance the capabilities of solid target stations at medical cyclotrons, a novel irradiation system based on an ultra-compact ~50 cm long beam line and a two-dimensional beam monitoring detector is under development to bombard targets down to few mg and few mm diameter. The first results on the production of Ga-68, Cu-64, Sc-43, Sc-44 and Sc-47 are presented.

Paul Scherrer Institute runs a High Intensity Proton Accelerator (HIPA) facility, where a maximum of 100 µA protons is gleaned from high intensity 72 MeV protons from Injector 2, a separated sector cyclotron, into the IP2 target station. These protons irradiate various targets towards the production of exotic radionuclides intended for medical purposes. Many radiometals in use today are for the diagnosis of disease, with the most popular means of detection being Positron Emission Tomography. These positron emitters are easily produced at low proton energies using medical cyclotrons, however, development at these facilities are lacking. The 72 MeV proton beam is degraded at IP2 using niobium to provide the desired energy to irradiate targets to produce the likes of 44Sc, 43Sc, 64Cu and 165Er*,**,***. Once developed, these proofs-of-principle are then put into practice at partner facilities. Target holders and degraders require development to optimize irradiation conditions and target cooling. Various options are explored, with pros and cons taken into consideration based on calculations and simulations.

V. to centralize the main units: a high current proton cyclotron, a radiopharmaceutical production – GMP unit including quality control, laboratories for PET-radiochemistry, chemical and biochemical laboratories and laboratories for small animal imaging. The cyclotron TR-Flex was put into operation in 2017 and it is equipped with two extraction ports. Both are movable to adjust the proton energy in the range from 15 MeV up to 30 MeV. One extraction port is coupled with a combination magnet and two beam lines. A [123I]I-gas target station is installed at the first beam line and a four-port target selector at beamline two and at the second extraction port. Two [18F]F-water targets, a [18F]F2-gas target, a [11C]CH₄-gas target, a [11C]CO₂-gas target, a 30° and a 90° solid state target are mounted on the target selectors. In our contribution we report our experience of the new cyclotron during the first two operation years. Typical beam parameters and the reliability of the TR-FLEX are presented. Furthermore we describe the new home-built Radionuclide Distribution System.

Quasi-monoenergetic neutron beams are typically produced at the iThemba LABS fast neutron beam facility by the 7Li(p, xn) or 9Be(p, xn) reactions. With the proton beams available from the separated sector cyclotron, the neutron energy range from about 30 MeV to 200 MeV can be covered almost continuously. The facility first became operational in the late 1980s. The fast neutron beam facility at iThemba LABS has been designated by the National Metrology Institute of South Africa (NMISA) as an entity responsible for providing traceability for the medium and high-energy neutron measurements in South Africa. As a result, the facility is undergoing a major upgrade and development in order for it to meet the requirements for a medium and high-energy neutron metrology facility. As part of the ongoing upgrade, Monte Carlo (MC) simulations aimed at benchmarking the experimental data are ongoing.

The high intensity proton accelerator (HIPA) at the Paul Scherrer Institut (PSI) delivers 590 MeV c.w. proton beam with currents of up to 2.4 mA, i.e. 1.4 MW beam power, For experiments of nuclear and material research the beam is directed to the 4 or 6 cm graphite 1 Hz rotating target (Target E). Centring the beam on the target is an important task for the operation and has safety issues in case of beam misalignment. Transmission monitoring has been the standard method to optimize the beam position on the target, though not very sensitive. A new method is currently being tested that provides a more sensitive off-axis detection. It is based on the detection of beam inten-sity modulation from the milled grooves at the target edge. This paper presents the concept and preliminary experimental results that can be obtained with this method.

At the Forschungszentrum Jülich (FZJ) the energy variable cyclotron JULIC is used as injector of the Cooler Synchrotron (COSY) and for low to medium current irradiations of different types. Recently a new target station was set up and is mainly used for tests of new target materials, neutron target development and neutron yield investigations with high power proton or deuteron beam in perspective of a high brilliance accelerator based neutron source (HBS) with the Jülich Center for Neutron Science. The neutrons are produced exposing material targets or compounds to proton or deuterium particles of relative low final particle energy in the MeV range and will be optimized for neutron scattering to be realized at reasonable costs. Beside this, ToF-experiments are performed to investigate and optimize the pulsing structure for HBS. The target station is installed inside an experimental area offering space for complex detector and component setups for nuclear and neutron related experiments. But it is used for other purposes like electronic or detector tests and irradiation as well. This report briefly summarizes the history of JULIC and the activities for its future perspectives.

The HZB cyclotron has been providing protons for eye-tumor treatment for more than 20 years. While it has been very successful using conventional dose rates (15-20 Gy/min), recent studies indicate that rapid irradiation with very high dose rates (FLASH) might be equally efficient against tumors but less harmful to healthy tissues. The flexible operation schemes of the HZB cyclotron can provide beams with variable intensities and time structures, covering a wide unexplored regime within the FLASH requirements (>40 Gy/s in <500 ms). This paper presents the results of the first FLASH beam production at HZB towards the establishment of an in-vivo clinical irradiation in the future.

A 70 MeV H⁻ cyclotron commercially available for medical isotope production will be used as an ISOL driver for rare isotope science project in Korea. The cyclotron is scheduled to be installed in 2021 for beam commissioning in the following year. In fact the building to house the cyclotron is currently almost complete so that the cyclotron system newly contracted needs to fit into the existing building, which brings some challenges in equipment installation and adaptation to utilities. Two beam lines to transport high-current proton beams into ISOL targets have been designed and are described along with other issues associated with the interface of the ISOL system.

Funding: This project was supported by the NSTIP Strategic Technologies Program in the Kingdom of Saudi Arabia, award no. 14-MAT-1233-20.
This paper reports a method to reduce the beam energy of the CS-30 cyclotron from 26.5 up to 10 MeV using the internal target system in CS-30 cyclotrons for isotopes production. Irradiation of solid targets, in this type of cyclotrons, take place when the target is positioned horizontally inside the cyclotron tank. In its final position, the target plate interrupts the beam from completing its orbit and nuclear reactions take place. Calculations are made to determine the beam energy as a function of radius. Verification of the new method was achieved by producing pure Ga-68 at an energy level of 11.5 MeV.

An intense negative muon source MERIT (Multiplex Energy Recovery Internal Target) for the nuclear transformation to mitigate the long-lived fission products from nuclear plants have been proposed. For the purpose of proof-of principle of the MERIT scheme, a FFA (Fixed Field Alternating focusing) ring has been developed and beam experiments have been carried out. In this conference, the results of this study will be reported.

In 2017 the new cyclotron has been successfully commissioned and started the operation at Laboratori Nazionali di Legnaro (LNL) of INFN . The cyclotron is the proton driver foreseen for the Selective Production of Exotic Species (SPES) project, providing the high power beam for radioactive ion beams (RIBs) production by the ISOL technique. The SPES facility is today under construction and first low energy RIBs are expected to be available on 2021. The facility has been designed in order to exploit the versatility of the cyclotron in terms of wide range of energy and beam current extracted: 35-70 MeV energy and 20 nA - 500 µA of average current. Moreover, the possibility to extract at the same time two proton beams allows to share these both for experimental physics session and applications. In particular, at LNL a collaboration between private company and public institution will lead to a profitable synergy in R&D of new radioisotopes and the related production. In the session the results of the commissioning and the operation of cyclotron will be presented as well as the description of the SPES facility together with its potentiality in nuclear physics research and applications.

The beam line for radionuclide production on the PSI Cyclotron Facility starts with an electrostatic beam splitter, which peels protons of a few tens of microampere from a beam around two milliampere. The peeled beam is then guided onto a target station for routine production of a variety of radionuclides [1]. Beam Delivery Simulation (BDSIM), a Geant4 based simulation tool, enables the simulation of not only beam transportation through optics elements like dipoles and quadrupoles, but also particle passage through components like collimator and degrader [2-3]. Furthermore, BDSIM facilitates user built elements with accompanying electromagnetic field, which is essential for the modeling of the first element of the beam line, the electrostatic beam splitter. With a model including all elements from beam splitter to target, BDSIM simulation delivers a better specification of the beam along the complete line, for example, beam profile, beam transmission, energy spectrum, as well as power deposit, which is of importance not only for present operation but also for further development.

The first test beams of radioactive ions produced by the ion-guide-on-line (IGOL) system coupled to the charge-breeding electron-cyclotron-resonance ion source (CB-ECRIS) have been accelerated to high energy by the Texas A&M K500 cyclotron. The radioactive ions were first produced by energetic protons, provided by the K150 cyclotron, impinging on foil targets. Low charge-state ions were then swept by a flow of helium gas into an rf-only sextupole ion guide (SPIG) which transports them into the plasma of the CB-ECRIS. The K500 cyclotron and beam-line transport were tuned with analog beam before tuning the radioactive beam.
