In order to meet with the cooling power requirement around 130W at 165K, an U-shape pulse tube refrigerator was designed, fabricated and tested for the purpose of xenon gas re-condensation in a liquid xenon calorimeter. It will be used in the final calorimeter with 800L of liquid xenon inside. Because of relatively higher temperature operation, a simple-orifice configuration is applied for a phase shift. mechanism. The cooling performance was obtained under the same operating condition as the previously developed co-axial pulse tube refrigerator using 1.6kW GM compressor.
