Abstract

A light weight battery powered x-ray source capable of producing high intensity x-ray emissions with low power consumption. A modular construction locates all high voltage components including the x-ray tube, spark gap trigger, spiral capacitor and the secondary of a step-up transformer in a sealed canister which can be decoupled both mechanically and electrically by unscrewing a simple threaded coupling. A center module contains the primary of the step-up transformer, circuit boards for electronic components and a pulse counter/selector. A battery pack with rechargeable Nicad batteries is removably connectable to the center module. High intensity pulses are achieved in part by connecting the spiral capacitor at midlength to the spark gap trigger. An improved x-ray tube with light weight but effective lead shielding and an overall length of less than two inches is also disclosed.
