A novel natural circulation evaporative cooling system for super-high power intensity ECR ion sources

Cooling is very important for the safe operation of an electron cyclotron resonance ion source （ECRIS）, especially when the window current density is very high （up to 11 A/mm2）. We proposed an innovative cooling method using evaporative cooling technology. A demonstration prototype was designed, bui...

Summary:Cooling is very important for the safe operation of an electron cyclotron resonance ion source （ECRIS）, especially when the window current density is very high （up to 11 A/mm2）. We proposed an innovative cooling method using evaporative cooling technology. A demonstration prototype was designed, built and tested. The on-site test results showed that the temperature of the solenoids and permanent magnets maintains well in the normal operational range of 14-18 GHz. A simple computational model was developed to predict the characteristics of the two-phase flow. The predicted temperatures agreed well with the on-site test data within 2 K. We also proposed useful design criteria. The successful operation of the system indicates the po- tential for broad application of evaporative cooling technology in situations in which the power intensity is very high.
