Longitudinal drift compression and pulse shaping for high-intensity particle beams
Physical Review Special Topics. Accelerators and Beams, 2002 High beam current can be achieved by longitudinally compressing bunched beams. The objective of drift compression is to compress a long beam bunch by imposing an initial longitudinal velocity distribution over the length of the beam in the beam frame ...
