Abstract: We investigate a scheme for electron cooling of ion beams with large
momentum spread of ± (1%) accelerator (IndAcc) is utilized to accelerate
or decelerate the stored ion beam in order to shift its momentum distribution
toward the sensitive region of the electron cooling force. This method will be
applied for further cooling of phase rotated hot ion beams produced by a
high-power short pulse laser, to be used as an injection beam for synchrotron.
Also, an induction accelerator has been designed for construction at the HIMAC
ring, which will be used to test the feasibility of the present sweep scheme
experimentally.
