MOB02	Simulation and Detection of the Helical Ion-Paths in a Small Cyclotron	ion, simulation, acceleration, cyclotron	21
	C.R. Wolf FZJ, Jülich, Germany M. Prechtl, R. Rueß HS Coburg, Coburg, Germany
	The small cyclotron COLUMBUS, which was developed by Gymnasium Ernestinum in cooperation with the University of Applied Sciences of Coburg, is a particle accelerator for education and teaching purposes. Since its inception, the cyclotron has been under continuous development and is part of the newly established student research center of the University of Applied Sciences of Coburg. This cyclotron accelerates hydrogen ions; the positions of them are registered after a few revolutions by a faraday cup which is moved across their paths by a Linear Translator. This thesis presents a MathLab Simulation of the orbits of the accelerated Hydrogen ions. In contrast to simpler models, which approximate the orbits in the acceleration gap by a straight line, this simulation takes into account the deflection by the magnetic field to get a more realistic result for the initial paths and the positions on which the ions are registered.

MOP18	Activities for Isotope Sample Production and Radiation Effect Tests at JULIC/COSY Jülich	proton, cyclotron, target, radiation	98
	O. Felden, M. Bai, R. Gebel, R. Hecker FZJ, Jülich, Germany
	At the Forschungszentrum Jülich (FZJ) the intermediate energy cyclotron JULIC, used as injector of the Cooler Synchrotron (COSY) and COSY itself, have been enabled to perform low to medium current irradiations. Main task is to support the FZJ radionuclide research programme of INM-5. Target holders of the INM-5 were implemented to the external target station of JULIC to obtain reliable irradiations with 45 MeV protons and 76 MeV deuterons for nuclear reaction cross section measurements and medical radionuclide production. For testing of radiation effects, displacement damage DD and single event effects SEE, with energetic protons for electronics used in space and accelerators the beam can be extracted to a dedicated test stand, e.g. used by Fraunhofer INT. To provide these possibilities up to 2.5 GeV as well one external beamline of the cooler synchrotron COSY will be equipped with a new irradiation station and adaption for the dosimetry systems are done. Different dosimetry systems (PTW Farmer® chambers, Bragg Peak chambers, Gafchromic® dosimetry films) are available to monitor and control the ongoing irradiation. This report briefly summarizes the relevant technical activities.

TUP08	The Use of Graphene as Stripper Foils in the Siemens Eclipse Cyclotron	cyclotron, ion, target, ion-source	181
	S. Korenev, R. Dishman, A. Martin Yebra Siemens Medical Solutions Molecular Imaging, Knoxville, TN, USA N.D. Meshcheryakov, I.B. Smirnov Siemens Healthcare, Moscow, Russia I. Pavlovsky ANI, Austin, USA
	This paper presents the results of an experimental study for the use of graphene foils as an extractor (stripper) foil in the 11-MeV Siemens Eclipse Cyclotron. The main advantage of graphene foils compared with carbon and graphite foils is its very high thermal conductivity. The graphene also has significant mechanical strength for atomically thin carbon layers. The life time of these foils is more than 1,8 times more in compare with specification. The graphene foils showed a significant increase in the transmission factor (the ratio of the beam current on the stripper foil to the current on the target), which was approximately 90%. The technology in fabricating these graphene foils is shown. The pros and cons of using the graphene material as a stripper foil in cyclotrons are analyzed.

TUP12	High Accuracy Cyclotron Beam Energy Measurement using Cross-correlation Method	cyclotron, pick-up, proton, real-time	193
	A.M. Hendy, F.M. Alrumayan King Faisal Specialist Hospital and Research Centre, Riyadh 11211, Kingdom of Saudi Arabia H.A. Kassim, K. Kezzar KSU, Riyadh, Kingdom of Saudi Arabia
	Funding: This project was supported by the NSTIP strategic technologies program in the kingdom. Award No. (14-MAT-1233-20) This work discusses a method to measure the protons energy from the CS 30 Cyclotron at KFSHRC. Using two Fast Current Transformers (FCT), particles' Time of Flight (ToF) can be accurately determined by using windowed cross-correlation method. Existing techniques use pulse width or edge delay measurement to get the ToF. The accuracy of these methods, however, is limited by sampling rate, signal level, noise, and distortion. By using Cross-Correlation and interpolation, on the other hand, a fractional delay measurement can be obtained, and the system works with low level signals, i.e. high S/N ratio. During experiments, time delay measured between the two signals was 9.4023 ns. By using relativistic equations cyclotron energy was calculated and found to be 25.99 MeV, bearing in mind that cyclotron energy (mentioned in the CS30 manual) is 26.5 MeV for protons. The difference between actual and calculated energy was <2%. Results will be further discussed and analyzed. S.

THP04	Status of the COSY/Jülich Injector Cyclotron JULIC	cyclotron, ion, operation, ion-source	310
	H.P. May, M. Bai, O. Felden, R. Gebel FZJ, Jülich, Germany
	The institute for nuclear physics IKP-4 at the Forschungszentrum Jülich operates the accelerator facility COSY with the isochronous cyclotron JULIC as the pre-accelerator, the cooler synchrotron COSY/Jülich and various experimental facilities for accelerator research and experimental hadron physics developments. The cyclotron has reached in spring 2016, since first beam in 1968, in total about 285000 hours of operation. The ongoing program at the facility foresees increasing usage as a test facility for accelerator research and detector development for realization of FAIR and other novel experiments. In parallel to the operation of COSY the cyclotron beam alone is also used for irradiation and nuclide production for fundamental research. Experience with pulsed ion sources for JULIC enables the development of a dedicated pulsed 100 keV source for protons and negative ions as a contribution to the extra low energy anti-proton synchrotron project ELENA at CERN's anti proton decelerator AD. A brief overview of the activities at the Forschungszentrum Jülich, the cooler synchrotron COSY and its injector cyclotron JULIC, with focus on recent technical developments, will be presented.

THC01	KURRI FFAG's Future Project as ADSR Proton Driver	neutron, acceleration, proton, simulation	366
	Y. Ishi, Y. Kuriyama, Y. Mori, M. Sakamoto, T. Uesugi Kyoto University, Research Reactor Institute, Osaka, Japan
	The accelerator complex using FFAG synchrotrons at KURRI* has been operated for the ADSR experiments connecting the 100 MeV proton beam line with the research reactor facility so called KUCA* since 2009. Fruitful results have been produced for the reactor physics using various configurations of the nuclear fuel core and variations of the neutron production target. Since higher energy beams such as 300 - 500 MeV are desired for the further study of the ADSR system, we are investigating the energy upgrade possibility of the accelerator complex. One of the candidates is to construct a new FFAG ring which adopts continuous acceleration with fixed frequency (serpentine acceleration) outside of the existing. These higher energy beams can be used for neutron or muon production experiments as well as ADSR study.

	A proof-of-principle test-stand for proton radiography is under construction at China Institute of Atomic Energy (CIAE). This test-stand will utilize the 100 MeV proton beam provided by the compact cyclotron CYCIAE-100, which has been built in the year of 2014, to radiograph thin static objects. The assembling of the test-stand components is finished by now. We will carry out the first proton radiography experiment in this July and hopefully we can get the first image before the opening of this conference. In this paper, the designing, constructing and commissioning of the proton radiography system will be described and the experiment result will be presented and discussed.
