  Since several years, caesium telluride photocathodes are successfully used in the photoinjector of the Free-Electron-Laser FLASH at DESY, Germany. They show a high quantum efficiency and long lifetime and produce routinely thousands of bunches per second with a single bunch charge mostly in the range of 20 pC to 3 nC. Recent studies on lifetime, quantum efficiency, darkcurrent, and operating experience is reported.
