    "abstract": "Ferroelectric ceramics are tested as photocathodes at INFN Frascati\nLaboratories. In order to characterize them for use in linac injectors it is\nimportant to measure the temporal shape of the emitted current. With a duration\nof the laser pulse of 25 ps, the required resolution is a few ps. An apparatus\nhas been set up for the purpose, consisting of a 30 kV electron gun, a\nmicrowave deflecting cavity which translates the temporal distribution of the\nelectron bunch into a spatial one, a fluorescent screen on which the deflected\nbeam traces a sector of a circle and various focusing and charge measuring\nitems. The image on the screen is detected via a CCD camera and a frame\ngrabber. We describe the performance of the apparatus and some preliminary\ntemporal distribution measurements.",
