Abstract
Evaporative cooling has been used successfully in EBIT to extend the containment time for neon‐like gold to several hours. This paper discusses a theoretical basis for evaporative cooling. Also included is an assessment of the processes which affect the temperature and number balance of the trapped and coolant ions in EBIT, and how the basic operating parameters affect these processes. Results of computer calculations using nitrogen as a coolant are presented and compared with an approximate analytic solution.Keywords
