Cockcroft-Walton voltage multiplying circuit for slim hole well logging tool

A Cockcroft-Walton voltage multiplying circuit adapted for use in a slim hole well logging tool comprising a plurality of capacitor means including a first capacitor means, adapted to receive an input voltage, and a last capacitor means;

• a plurality of high voltage rectifier means, each rectifier means, except for a last rectifier means, physically as well as electrically interconnect two capacitor means and the last rectifier means being connected to the last capacitor means so that all the capacitor means and rectifier means form an in-line rigid body, and each rectifier means includes a non-conductive plastic body having two ends, adapted to fit over ends of the capacitor means with clearance holes for the capacitor means terminals, three channels and two threaded holes;
• a non-conductive plastic cap which fits between the ends of the plastic body having two counter sunk clearance holes which align with the receivers of the body, and two screws for securing the cap to the body when threaded into the threaded holes;
• and output means connected to the last rectifier means for providing a high voltage developed by the capacitor means and the rectifier means.
