Abstract
Abstract An electromagnetic implosion X-ray source having a thin cylindrical metal foil supported on spaced electrodes within an evacuated chamber. The electrode system is connected through a switch to a capacitor bank power supply with low inductance leads and with the average electrical impedance of the dynamic plasma being matched to the impedance of the power supply. An X-ray radiation path is provided between the X-ray source and a sample holder attached to the X-ray source.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
An implosion X-ray apparatus, comprising: an enclosed container; means for evacuating said container to a predetermined vacuum; a first disc-shaped electrode witHin said container; a second disc-shaped electrode within said chamber spaced a predetermined distance from said first electrode; a thin cylindrical electrically conducting foil secured to the outer cylindrical surfaces of said electrodes; means for supplying a high energy current pulse to said electrodes and foil to thereby convert said foil to a high temperature, high energy density plasma and means for providng an X-ray path from the space between said electrodes external to said container whereby said X-rays produced by implosion of said plasma may be utilized.
Claim 2
Dependent Claim
109 words

Claim 3
Dependent Claim
41 words
The device as recited in claim 1 including a three part split clamp ring surrounding said foil adjacent the outer cylindrical surface of each electrode and an O-ring retaining the split clamp rings in position around the foil and the electrodes.
Claim 4
Dependent Claim
16 words
The device as recited in claim 2 including means for viewing the implosion between the electrodes.
