Abstract: This discloses a device called a particle refrigerator that will reduce the emittance of a charged particle beam. The particle refrigerator device is particularly well-suited for beams of particles created by interactions or decays of other particles, such as anti-protons, pions, ions, and muons, which are inherently created with very large emittances. It is a compact and inexpensive device compared to other systems for the emittance reduction of such beams. This device works by injecting beam particles backwards into the device, using the particle turn-around to match an incoming beam into a frictional cooling channel; this increases the acceptance of that channel by perhaps a thousandfold, making it practical to produce beams of high intensity and brightness. The frictional cooling is very effective, and simulations of its operation and performance give emittance reduction factors exceeding 30,000, with transmissions as high as 70%.
