Abstract
Abstract A high desnity pulsed plasma generator is disposed in axial alignment with a high energy pulse laser to receive laser radiation from the laser axially to the movement of the plasma blob along the centterline of the center electrode of the plasma gun. A high Z-material is disposed between the laser output and the plasma for evaporation by the laser and subsequent injection of heavy z-ions into the plasma for enhancing x-ray radiation from the plasma. Electrrical circuit means is provided for energizing the plasma gun and the laser at predetermined times.

Claim 1
Independent Claim
168 words
A laser assisted x-ray generator comprising a pulsed plasma generator for generating a plasma, said plasma generator having center and outer concentric electrodes; pulsed laser means for producing a laser beam for conditioning said plasma for enhanced radiation of x-rays, said laser beam being compatible with said plasma so that the plasma will absorb energy therefrom, said laser means being disposed in axial alignment with said center electrode; a member of high ionic charge ions disposed for vaporization by said laser beam for injection into said plasma for enhanced radiation of x-rays from said plasma; a lens positioned coaxially with said center electrode of said plasma generator for focusing the laser beam into said plasma generator; triggering means connected to said laser for triggering said laser; light sensing means positioned so as to detect the light energy in said plasma generator and to generate a signal upon the light energy reaching a predetermined value, said signal disposed for triggering said triggering means into operation at a predetermined time.
