Characterization of multiterawatt laser-solid interactions for proton acceleration

Abstract:

The characterization of multiterawatt laser-solid interactions for proton acceleration was discussed. The stages of ionization of a target gas was investigated using time-of-flight spectrometer. Results showed a factor of 1.5 uncertainity in the focused intensity when ion yields were measured with predictions of an atomic tunneling ionization. A maximum proton energy of 1.5 MeV was also observed.

Abstract:

The Vulvan Nd:glass laser at the Central Laser Facility (CLF) has recently been upgraded to the Petawatt level (1015 Watts). The three year upgrade project was contracted to deliver 500 J in a near diffraction limited pulse of 500 fs duration. The Petawatt facility will deliver an irradiance on target of 1021 W.cm-2 for a wide ranging experimental programme in fundamental physics and advanced applications. This includes the interaction of super-high intensity light with matter, fast ignition fusion research, photon induced nuclear reactions, electron and ion acceleration by light waves and the exploration of the exotic world of plasma physics dominated by relativity. Of particular relevance to high speed photography, the Petawatt beam will be used to create a source for advanced high-speed imaging using protons, neutrons and X-rays on an hitherto inaccessible time-scale.
