PERFORMANCE TEST OF CRYOCONDENSATION PUMP FOR NEUTRAL BEAM INJECTOR

The neutral beam injector is a set of equipment that is used to produce energetic particles and then neutralize them. Excellent dynamic vacuum performance is the key factor for getting high beam transmission efficiency. The performance of the cryocondensation pump mounted in main vacuum vessel is tested. The results indicate that the required dynamic vacuum can be met by using the cryocondensation pump.
