MOP05	An Air Ionization Chamber Simulation using Monte Carlo Method	simulation, cathode, radiation, photon	57
	S.G. Hou, Shizhong. An, Z.W. Liu, G.F. Song, F. Wang, L.P. Wen, T.J. Zhang CIAE, Beijing, People's Republic of China
	The CYCIAE-100 cyclotron has been built at CIAE, designed to achieve 200 μA protons at 100 MeV and deliver them to several experimental targets. To achieve this goal and protect the machine from excessive radiation activation, an uncontrolled loss criteria of 1uA has been specified. Previous calculation for radiation shielding showed that high neutron and gamma were produced under this condition. To measure the high energy gamma ray(about 2 MeV ) at machine running and void damage by the prompt radiation, an air ionization chamber was designed to fulfill this goal. A Geant4 program was developed to simulate the energy response of detectors, the EM filed data was also taken into consideration in the programl. The simulation results indicate that the energy response linearity satisfies the requirement of the project specification.

MOP19	A Diamond Detector Test Bench to Assess the S2C2 Beam Characteristics	proton, extraction, emittance, timing	102
	J. van de Walle, S. Henrotin, Y. Paradis, I.C. Tkint IBA, Louvain-la-Neuve, Belgium
	The fast timing capabilities, compactness, high sensitivity and radiation hardness of diamond detectors make them ideally suited for measurements in the pulsed beam from the S2C2. In this communicaiton, we will present first results obtained on the S2C2 with such a diamond probe and the mechanical design of a dedicated test bench to be used for factory tests. The test bench is able to measure the beam direction, the intensity distribution in the beam, the emittance (with an emittance slit) and the exact moment when the beam is extracted from the S2C2. We are able to measure the frequency at which the protons are extracted from the S2C2 and to observe small (<100 keV) mean energy fluctuations in the extracted beam. All these measurements can be done with extreme low beam intensities so that activation of the S2C2 is highly reduced.

TUD01	Compact Medical Cyclotrons and their use for Radioisotope Production and Multi-disciplinary Research	cyclotron, ion, target, ion-source	229
	S. Braccini LHEP, Bern, Switzerland
	Compact medical cyclotrons are conceived for radioisotope production in a hospital-based environment. Their design in terms of field shape, stability and RF is aimed at obtaining high intensity (~150 microamps) beams at kinetic energies of the order of 20 MeV. To guarantee high performances, an optimization procedure during the commissioning phase is crucial as well as a regular preventive maintenance. Beyond radioisotope production, these accelerators can be the heart of a multi-disciplinary research facility once access to the beam area and beams down to the pA range are possible. The first requirement can be achieved by means of an external beam transport line, which leads the beam to a second bunker with independent access. Currents down to the pA range can be obtained by specific ion source, RF and magnetic field tuning procedures, opening the way to nuclear and detector physics, radiation protection, radiation bio-physics and ion beam analysis developments. On the basis of the experience gained with the cyclotron at the Bern University Hospital, the accelerator physics aspects of compact medical cyclotrons will be discussed together with their scientific potential.
