Towards experimental areas

Available stable beams at Ganil

CSS1 beams: from 12C (4 to 13.5 A.MeV) to 238U (4 to 8 A.MeV) intensities: several pA for light ions < 1 pA for A > 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

Ongoing R&D:Ion production methods: development of Ni, Ca, Ge…

Needed R&D:

If necessary, possibility of increasing the intensity of light ions, byadding 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

Spiral2 project

Associated R&D:The accelerator is based on almost known technology (normal conductingRFQ, quarter-wave SC cavities for the SC linac, the couplers have to bedeveloped 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)
