摘要：

The length of electron beam from a photocathode RF gun is determined by a spectrometer, according to the relative energy spread induced by the bunch length during the acceleration in a linac. For a photocathode RF gun, different laser injected phase and beam charge are studied. The compression is changed for the different laser phases, as from 10 ° to 30 ° , and the bunch length is lengthened due to the strong longitudinal space charge force, caused by the increased charge.
