MOPRI001	Induced Heating Power Evaluation in RIB Transfer Line of SPIRAL2	ion, beam-losses, solenoid, space-charge	570

	Radioactive Ion Beams of SPIRAL2 project will be produced in the ECR ion source using the Helium as supporting gas. RIB transported in the transfer lines have a multi-component structure and total current of the beams is defined by Helium ions. The total power of Helium component may reach 300 W. The focusing force acting on the ions in the transfer beam line is strongly dependent on mass-to-charge ratio (this is valid for magnetic optical elements). For this reason supporting gas ions will be lost at initial part of the beam line between ECR ion source and analyzing magnet. The Helium beam losses and induced heating power density at the wall of vacuum tube in RIB transfer line of SPIRAL2 during transportation of Ar, Xe and U ion beam are evaluated in this report.

MOPRI083	Improvement of the Beam Transmission in the Central Region of Warsaw U200P Cyclotron	cyclotron, ion, ion-source, injection	803
	O. Steczkiewicz, P. Gmaj HIL, Warsaw, Poland V. Bekhterev, I.A. Ivanenko JINR, Dubna, Moscow Region, Russia
	To date, Warsaw U200P cyclotron exploited a mirror inflector to route heavy ions extracted from ECR ion source (10 GHz, 11 kV) to the central region of the cyclotron. However, in such configuration very low transmission was reachable after many optimizations. Additionally, the new ECR ion source (14, 5 GHz, 14-24 kV) was installed, which offers energies far exceeding capabilities of the currently operated inflector and central region. To overcome these obstacles, we have developed a spiral inflector and redesigned central region of the cyclotron. It was a very challenging task, bearing in mind limited volume of central region in our compact machine, to carve these elements suitably for decent versatility of ion beams offered by Warsaw cyclotron. This project was executed in the collaboration with FLNR in Dubna, Russia. The cyclotron equipped with the new central region works in the "constant orbit" regime. Hereby we present the results of both computational simulations and measurements of the beam transmission in upgraded central region.

MOPRI085	IMALION – Creation and Low Energy Transportation of a Milliampere Metal Ion Beam	ion, ion-source, simulation, plasma	809

	Funding: This work is supported by the European Regional Development Fund (ERDF) and the Freistaat Sachsen (project no. 100074113 and 100074115). IMALION – which stands for IMplantation of ALuminum IONs – is a facility originally designed for applications in photovoltaics and other branches in semiconductor industry. The idea was to create and guide a milliampere beam of low charged metal ions so that targets with a width of 20 cm and more can be irradiated homogeneously with minimal differences in intensity and entrance angle of the incoming beam over the entire surface. In this poster, we outline the solutions which had to be found during the realization of the project. This concerns the production of a milliampere metal ion current in a newly designed electron cyclotron resonance (ECR) ion source combined with an internal sputter magnetron device. Stable operation of the sputter magnetron under ECR magnetic mirror conditions has been proven by optical spectroscopy and Langmuir probe measurements. Furthermore, electrostatic and magnetic beamline elements developed for precision guiding of a low energy but high intensity beam as well as high intensity ion beam diagnostics are presented and ion beam transportation simulations are shown.

	Funding: Supported by the Rare Isotope Science Project of Institute for Basic Science funded by Ministry of Science, ICT and Future Planning and National Research Foundation of Korea Project No. 2011-0032011 Raon, the rare isotope accelerator of the the Rare Isotope Science Project (RISP) in Daejeon, South Korea, is being designed to accelerate multiple-charge-state beams simultaneously. Using an Electron Cyclotron Resonance (ECR) Ion Source to produce the ions, Raon will transport the beam through two 90-degree bending magnets and a Low Energy Beam Transport (LEBT) system to a Radio Frequency Quadrupole (RFQ). In order to test the components of the injector and LEBT system, a test facility is under development. A new LEBT, based upon the LEBT of the main driver linac, is being designed to fit within the test facility’s restrictive space requirements. This work will briefly review the main driver linac LEBT design, and then discuss the current status of the test facility LEBT design.

	The coupled RFQ and SFRFQ cavity has been manufactured and tested recently. According to the beam dynamic design, the input He⁺ beam within 120° phase width is designed for the cavity to achieve over 98% transmission efficiency. An energy modulated electron cyclotron resonance (ECR) ion source was proposed and simulated. To achieve the 1% energy modulation on the 30keV direct current (DC) beam, two simplified RF power feeding structures for beam bunching were studied. The simulations show positive results as well as the bunched beam is achieved by the energy modulated ECR ion source.
