Abstract
Abstract A high density pulsed plasma generator produces a high temperature plasma which is sensed by a photo switch which in turn triggers the operation of a high energy pulse laser. The frequency of the laser light is such that the plasma will absorb it. The laser is disposed in coaxial alignment with the center electrode of the plasma gun so that the high energy laser radiation illuminates the plasma blob axially to its motion with respect to the center electrode of the coaxial plasma gun.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
A laser assisted neutron generator comprising a pulsed plasma generator for generating a plasma; pulsed laser means for producing a laser beam which is compatible with the plasma so that the plasma will absorb energy therefrom, said plasma generator and said laser means being disposed in axial alignment so that the laser radiation illuminates the plasma axially to its motion with respect to the center line of said plasma generator; transferring means for directing said laser beam to said plasma so as to heat said plasma; triggering means connected to said laser so as to trigger the laser; a light sensing means positioned so as to detect the light energy in the plasma generator and to generate a signal upon the light energy reaching a predetermined value; said signal being connected to said triggering means so as to set said triggering means into operation whereby said laser will produce its laser beam at the same time the plasma is generated.
Claim 2
Dependent Claim
