2. Laboratoire Commun CEA/DSM-CNRS/IN2P3 Orsay June 4 th 2004 M-H MoscatelloHigh Intensity Stable Beams Towards experimental areas Available stable beams at Ganil CSS1 beams: from 12 C (4 to 13.5 A.MeV) to 238 U (4 to 8 A.MeV) intensities: several p A for light ions 40 possibility of simultaneous beams in SME and HE experimental areas (using a stripper) CIME beams: from He to Xe a few pnA between 2 and 25 A.MeV depending on q/A

Laboratoire Commun CEA/DSM-CNRS/IN2P3 Orsay June 4 th 2004 M-H MoscatelloHigh Intensity Stable Beams Ongoing R&D: Ion production methods: development of Ni, Ca, Ge… Needed R&D: If necessary, possibility of increasing the intensity of light ions, by adding a rebuncher at the entrance of the C01 injector cyclotron (the light ion intensity limitation is due to space charge effects near the cyclotron injection) Targer development needed for low energy ion beams (Coulomb barrier) and several kWatts thermal power

Laboratoire Commun CEA/DSM-CNRS/IN2P3 Orsay June 4 th 2004 M-H MoscatelloHigh Intensity Stable Beams Spiral2 project Spiral2: q/A=1/3 ions 1mA (Ar) from 0.75 to 14.5 A.MeV able to accelerate 5mA D + beam up to 20 A.MeV lower intensities avalaible (Cr, Ni,…) 2 nd step: q/A=1/6 ions 1mA (Xe) from 0.75 to 6.5 MeV/A

6. Laboratoire Commun CEA/DSM-CNRS/IN2P3 Orsay June 4 th 2004 M-H MoscatelloHigh Intensity Stable Beams Spiral2 project Associated R&D: The accelerator is based on almost known technology (normal conducting RFQ, quarter-wave SC cavities for the SC linac, the couplers have to be developed for 10 to 20 kW/cavity (under design). The challenge is mainly the high intensity to be accelerated, without any losses -during the construction phase, development of high intensity q/A=1/3 beams like Cr, Ni with the GTS source (ex. SBT/CEA source) at Ganil -during the APD and construction phase, development of a new source (APHOENIX) that will produce 1mA beams with A as high as possible Needed R&D but not really identified yet in the frame of Spiral2: development of adapted targets, able to handle these beams (up to 40 kW beams)
