Abstract
An apparatus and method for the phase-transition cooling of particle-transparent windows in charged particle accelerator systems, wherein the apparatus and method permit the operation of the particle-transparent window at a desired temperature by directing an atomized, vaporizable coolant liquid over the window surface, the coolant liquid having a boiling point approximately equal to the desired operating temperature of the window, so that heat is absorbed as the liquid coolant changes from a liquid phase to a gaseous phase.
