Abstract:
High-energy protons are generated by focusing an ultrashort pulsed
high intensity laser at the Advanced Photon Research Center, JAERI-Kansai onto thin (thickness 〈 10 μm) Tantalum targets. The laser
intensities are about 4 × 10 18 W/cm 2 . The
prepulse level of the laser pulse is measured with combination of a PIN photo diode and a cross correlator and is less than 10 −6 .
A quarter-wave plate is installed into the laser beam line to create circularly polarized pulses. Collimated high energy protons are observed
with CH coated Tantalum targets irradiated with the circularly polarized laser pulses. The beam divergence of the generated proton beam is measured
with a CR-39 track detector and is about 6 mrad.
