TUPP03	Integration of a Third Ion Source for Heavy Ion Radiotherapy at HIT	ion, ion-source, extraction, emittance	46
	T.W. Winkelmann, A.B. Büchel, R. Cee, A. Gaffron, Th. Haberer, J.M. Mosthaf, B. Naas, A. Peters, J. Schreiner HIT, Heidelberg, Germany
	HIT is the first European hospital based facility for scanned proton and heavy ion radiotherapy. In 2009 the clinical operation started, since then more than 800 patients were treated in the facility. In a 24/7 operation scheme two 14.5 GHz electron cyclotron resonance ion sources are routinely used to produce protons and carbon ions. In the near future a helium beam for regular patient treatment is requested. The modification of the low energy beam transport line (LEBT) for the integration of a third ion source into the production facility was done in winter 2011. For beam quality improvement with a smaller emittance at the same current we designed and tested a new extraction system at the testbench and equipped the source for protons and helium with this optimized system. This paper will present results of the LEBT modification and gives an outlook to further enhancements at the HIT ion source testbench.

TUPP10	Operational Experience with the GTS-LHC Ion Source and Future Developments of the CERN Ion Injector	ion, linac, light-ion, heavy-ion	57
	D. Küchler, G. Bellodi, A.M. Lombardi, M. O'Neil, R. Scrivens, J.T. Stafford-Haworth CERN, Geneva, Switzerland R.W. Thomae iThemba LABS, Somerset West, South Africa
	Since 2010 the GTS-LHC source delivers lead ions for heavy ion physics at the LHC. Several modifications allowed improving the source reliability and the beam stability. The attempts to improve the beam intensity were less successful. The different modifications and actual performance figures will be presented in this paper. In addition to the heavy ion physics program of the LHC new ion species will be requested for different experiments in the future. The fixed target experiment NA61 requires primary Argon and Xenon beams. And a future radio-medical facility asks for light ions in the range Helium to Neon. Approaches to prepare these beams and to modify the ion injector towards a light ion front end are presented.

TUPP12	Design of Web-based Interface to RIKEN 28 GHz Super-conducting ECR Ion Source and the Future Plan	ECRIS, controls, EPICS, ion	61

	A new RIKEN 28 GHz superconducting ECR ion source (28 GHz-ECRIS) was constructed in 2009 in order to increase the intensity of Uranium ion beam for RIKEN RI beam factory project(RIBF). For effective and stable operation of the 28 GHz-ECRIS, its client system should have an user-friendly man-machine interface. The ECRIS control system was constructed with the Experimental Physics and Industrial Control System (EPICS) as well as RIBF control system. As a result, it was successful to provide the useful clients, such as the operation GUI panels, the XY chart application, and the data acquisition system in EPICS-based system. On the other hand, to keep beam quality from 28 GHz-ECRIS for a long beam service term, it should be possible to operate the ECRIS by members of ion source team at any time. In order to relieve concern in the overseas business trip of members of ion source team, we designed a real-time web-based client system using WebSocket, which is a new protocol presented by Internet Engineering Task Force (IETF). In this paper, we report the system and development status in detail. I. Fette and A. Melnikov. The WebSocket Protocol, IETF HyBi Working Group. 2011.

The source in combination with the K-200 cyclotron delivers high energy, high intensity beams for nuclear physics experiments. In this paper we present beam experiments with the GTS at iThemba LABS, in which the results of CW, pulsed and afterglow operation for different bias disc voltages and positions are compared.

	Funding: This work is partially funded by the European Commission under the 7th Framework Programme Grant Agreement 283745 (CRISP) The 18 GHz PHOENIX V2 ECRIS is running since 2010 on the heavy ions low energy beam transport line (LEBT) of SPIRAL2 installed at LPSC Grenoble. PHOENIX V2 will be the starting ion source of SPIRAL 2 at GANIL. The status and future developments of this source are presented in this paper. Recent studies with Oxygen and Argon beams at 60 kV have demonstrated reliable operation at 1.3 emA of O⁶⁺ and 200 eμA of Ar¹²⁺. Metallic ion beam production has been studied with the Large Capacity Oven developed by GANIL and 20 eμA of Ni¹⁹⁺ have been obtained. In order to improve further the beam intensities for Spiral2, an economical upgrade of the source named PHOENIX V3 has been recently decided by the project management. The goal is to double the plasma chamber volume from 0.6 to 1.2 liter by increasing the chamber wall radius, keeping the whole magnetic confinement intensity unchanged. The PHOENIX V3 magnetic design will be presented along with a status of the project.

WEPP15	Metal Ion Beam Production with Improved Evaporation Ovens	ion, ECRIS, ion-source, plasma	140
	K. Tinschert, R. Lang, J. Mäder, F. Maimone, J. Roßbach GSI, Darmstadt, Germany
	Most of the ion beams delivered by the ECR ion sources at the GSI accelerator facilities are produced from materials in the solid state, which must be transformed into the gaseous state to feed the plasma. The well established method of thermal evaporation has been used by means of two types of resistively heated ovens for metals and solid compounds. The main goal of development is to improve their versatility in terms of lifetime, durability, efficiency, and extended temperature range. Recent investigations and developments include the use of alternative materials for oven components. The main focus has been on the further development of the high temperature oven. A modular construction with improved mechanical dimensional accuracy for more precise and easier mounting has been established. Its optimization for stable long time operation has been continued leading to a lifetime of 6 days for evaporation of Ti at 1750°C. Furthermore the temperature limit could be extended to 2300°C. In addition to the improvements in evaporation technology the technique of microwave frequency tuning could be successfully applied for metal ion operation leading to enhanced ion beam intensities.

	Heavy-ion radiotherapy is successfully carried out at the Heavy Ion Medical Accelerator in Chiba (HIMAC) at the National Institute of Radiological Sciences (NIRS) since 1994. Now three facilities are in operation and two are under construction in Japan. Over 8000 cancer patients have already been treated. 140-400 MeV/u carbon beams were selected for the first clinical trials at HIMAC because carbon is one of the best candidates which gives good localized biological dose distribution for the typical conditions, a depth of 10 - 25 cm and a thickness of several cm. Based on the clinical results, all the patients have been treated by carbon beams at present. The ion source needs to realize a stable carbon beam with the same conditions for daily operation. Since operators are usually not specialists of the ion source, the source should not require complicated manual tuning. In addition, shorter maintenance time and cycle are better for a hospital. ECR ion sources are utilized for such requirements in each facility. We report the recent status of the ECR ion sources at heavy-ion radiotherapy facilities in Japan.
