Particle accelerator with a heat pipe supporting components of a high voltage power supply
First Claim
1. An apparatus for downhole logging, comprising:
- a) an enclosure having a metal target having a target face that generates neutrons in response to bombardment of ions accelerated thereto;
b) a high voltage power supply including (i) a high voltage power supply (HVPS) bulkhead and (ii) a plurality of electronic components electrically coupled to said target, wherein said plurality of electronic components generate a voltage with a magnitude of at least 50 kV; and
c) a heat pipe disposed between said HVPS bulkhead and said target, said heat pipe having a housing portion with an exterior surface supporting said plurality of electronic components of said high voltage power supply, said heat pipe being in thermal contact with said target and comprising a wick and heat transfer fluid disposed within said housing portion, the wick for circulating the heat transfer fluid within the housing portion in order to transfer heat away from the target to said HVPS bulkhead.

Abstract
A pulsed neutron generator includes neutron tube and a high voltage power supply. High voltage power supply includes a bulkhead and plurality of electronic components electrically connected between the bulkhead and the target of the neutron tube. A heat pipe is provided in thermal contact with the target and has a housing portion with an exterior surface supporting the plurality of electronic components of the high voltage power supply. Heat pipe includes wick and heat transfer fluid disposed within the housing portion. The wick for recirculates the heat transfer fluid within the housing portion in order to transfer heat away from the target preferably to the bulkhead for dissipation the system housing. Both the wick and heat transfer fluid are preferably realized from materials that have low electrical conductivity. The heat pipe can also be part of other-type particle accelerators, such as x-ray sources and gamma-ray sources.
