Description

In STF (Super-conducting Test Facility) at KEK, 40 MeV Linac based on 1.3 GHz super-conducting accelerator has been in commissioning since February 2012. The long macro pulse electron beam in 1ms in length and 10mA in average current is generated by Cs2Te photo-cathode in a normal conducting RF gun. The beam emission condition is quite different from the off-line conditions, e.g. surface field, high charge density, etc. In addition, it could be curious whether the emission property of the photo-cathode is stable over the 1ms macro pulse. We studied the beam emission property (QE; Quantum Efficiency) of Cs2Te photo-cathode in various conditions, varying surface field, emission density. QE variation in the macro pulse was also examined. (author)
