Title Effect of DC Photoinjector Gun Voltage on Beam Dynamics in ALICE ERL
Abstract The ALICE ERL employs a DC HV photoelectron gun as an electron source. As with other machines in this class, the electron beam is not always of a perfect quality. This is aggravated by the fact the ALICE gun has so far been operated at a lower voltage of 230kV, due to hardware limitations. The "two beams" structure was observed and experimentally investigated and found to be the result of complex processes during the initial stages of beam acceleration. The experimental observations and data are compared with those obtained at 325kV gun voltage. An investigation of the effect of the DC photogun voltage on longitudinal and transverse beam dynamics is presented and discussed.
