Study and Development of CW Room Temperature Re-Buncher for SARAF Accelerator
Abstract : The SARAF 176 MHz accelerator is designed to provide CW proton/ deuteron beams up to 5 mA and 40 MeV. Phase
I of SARAF (up to 4-5 MeV) has been installed, commissioned, and is available for experimental work. Phase II of
SARAF is currently in the design stage. It will contain larger MEBT with three rebunchers and four cryomodules, each
housing HWRs and solenoids. Phase II 4.5mlongMEBT line is designed to transport and match the 1.3MeV/u beam
from the RFQ to the SC LINAC. The MEBT contains three 176 MHz rebunchers providing a field integral of 106 kV
and reserves room for a future single bunch selector. Different rebuncher configurations have been studied in order
to minimize the RF losses and maximize the shunt impedance. Different apertures have been tested with a beam
dynamics requirement of 40 mm diameter. The simulations were done using parameter sweeps in CST Microwave
Studio. CEA leads the design for SARAF phase II linac including the MEBT rebunchers and has studied a mixed solid
copper, Cu plated stainless steel, 3-gap cavity. SNRCis developing a 4-gap OFHCcopper rebuncher as a risk reduction.
Both designs are presented and discussed in this paper.
