Emission of Energetic Electrons from a Nd-Laser-Produced Plasma.

Abstract

Absolute spectral measurements of 50-500 keV electrons emitted from a Nd-laser-produced plasma are presented. For normally incident irradiation (10 to the 15th power to 10th to the 16th power W/sq.cm.) onto polystyrene slab targets a total emission of about 10 to the 10th power electrons is inferred with a total emitted energy of about 0.2 mJ. The electron emission is observed to be almost the same both in and out of the plane of polarization. Properties of the emitted spectrum, such as spectral hardness and intensity are observed to be dependent on pulse shape and target material. (Author)
