Abstract

We have constructed a novel picosecond x-ray (PxR) source to be used for time resolved x-ray diffraction. The PxR source has a metallic photocathode from which photoemission is induced by ultraviolet picosecond laser.pulses. Electron bunches of over 3 nC have been produced with a tantalum photocathode excited by a frequency quadrupled pulsed modelocked Nd:YAG laser.The accelerated electron bunches strike a copper anode generating 6.2x10⁶ Cu Ka x-ray photons cm^-2.sr^-1 with a time width of less than 70 ps. A high energy Nd:YLF regenerative amplified laser was constructed to increase the repetition rate of the source to 2 kHz. Several detection methods and experimental schemes for PxR diffraction are presented
