Abstract :
The LBNL femtosecond-level X-ray source, now christened LUX, a source of hard X-rays with a pulse length in the 50-200 fsec range, will operate at a pulse rate of up to 10 kHz. The room-temperature 1.3 GHz photoinjector includes a modified re-entrant first-cell cavity which minimizes peak surface field, the addition of a third pi-mode acceleration cell, waveguide r.f. feeds to each cell, and an active energy removal procedure which reduces the wall power density of all four cells.
