Duration of multipacting processes and discharges in the linac of ions
It is experimentally shown that multipactor processes may be as harmful as other of parasitic discharges and cause significant disturbance in resonator electrodynamic characteristics of an accelerating structure. The disturbance may be evaluated by pulse-shape distortions of a reference rf voltage...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | It is experimentally shown that multipactor processes may be as harmful as other of parasitic discharges and cause
significant disturbance in resonator electrodynamic characteristics of an accelerating structure. The disturbance
may be evaluated by pulse-shape distortions of a reference rf voltage impulse. Control over duration of multipactor
processes within diode gaps of a linac is effected by varying parameters of a self-sustained oscillation system formed by
two independent positive feedback circuits (PFC). If two synchronous rf voltage pulses of given amplitude superpose
in the accelerating structure, there occurs an impediment to multipactor processes. As this takes place, multipactor
processes display minimal duration and do not affect acceleration stability. |
