GENERATION OF PICOSECOND X-RAY PULSES AND THEIR APPLICATION IN TIME-RESOLVED DIFFRACTION Conference Paper uri icon

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 ultra-violet picosecond laser pulses. Electron bunches of over 3 nC have been produced with a tantalum photocathode excited by a frequency quadrupled pulsed mode-locked Nd:YAG laser. The accelerated electron bunches strike a copper anode generating 6.2106Cu Ka X-ray photons cm-2sr-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
