Abstract

Adiabatic cooling is shown to be a simple and effective method to cool many charged particles in a trap to very low temperatures. Up to 3×106 p̄ are cooled to 3.5 K-103 times more cold p̄ and a 3 times lower p̄ temperature than previously reported. A second cooling method cools p̄ plasmas via the synchrotron radiation of embedded e- (with many fewer e- than p̄) in preparation for adiabatic cooling. No p̄ are lost during either process-a significant advantage for rare particles.
