Description
Possibility of increasing quantum efficiency of metal photocathodes by geometric alteration is being investigated. The fourth harmonic light of Nd:YAG is used to produce photoelectrons on a metal surface. The pulse length is about 50 ps (FWHM) and the peak current is greater than 2 A at 0.7 MeV. This scheme employs a grooved surface with adjusted polarization and other pertinent parameters such as extraction voltage. The measurements are done after acceleration by DISKTRON reg-sign electrostatic accelerator which, with a combination of a laser-induced photocathode, gives fairly controllable bright short-pulse-electron-beam up to the energy of over 1 MeV. This configuration permits the authors to find the overall improvement of e-beam characteristics for the future laser-undulator-experiment
