Abstract
A closed loop apparatus for spraying coolant against the back of a radiation target. The coolant is circulated through a closed loop with a bubble of inert gas being maintained around the spray. Mesh material is disposed between the bubble and the surface of the liquid coolant which is below the bubble at a predetermined level. In a second embodiment no inert gas is used, the bubble consisting of vapor produced when the coolant is sprayed against the target.
Claims2
A closed loop apparatus for spraying a radiation target with liquid coolant comprising:
- a loop for circulating the liquid coolant including a coolant reservoir, a gastight chamber communicating with the target, and first and second tubular connections between the reservoir and the chamber for circulating the liquid coolant therethrough;
- means disposed within the chamber and connected to one of the tubular connections for spraying the liquid coolant against the back of the target;
- said chamber containing vaporized coolant;
- a vacuum line interconnecting the reservoir with the chamber;
- an isolation valve;
- and
- a pump communicating with the vacuum line through the isolation valve.
