Operation of Argonne National Laboratory´s RF Particle Separator in the Travelling Wave Mode

Argonne\´s two RF deflector separated beam line has been operated in the travelling wave mode. It has produced a good yield 50% pure p¿ beam at 4.08 GeV/c. The operating frequency is lowered to make the phase velocity of the RF separator synchronous with the wanted particle. Results for p¿ beams at 2.57, 4.08 and 5.77 GeV/c are presented. In addition, the operation of the travelling wave separator in the "nonconventional" manner, i.e., phase velocity synchronous with unwanted particle, is described.
