【Abstract】 The approaches to obtain cryogenic and high temperature in vacuum （about 1Pa） and radiation environment (10⁴ fissions per second for ²⁵²Cf source accompanied by 10⁴ neutrons per second) are investigated, especially on techniques to obtain cryogenic temperature （-55～20℃）. Cryogenic and high temperature apparatus is established suitable for ²⁵²Cf source radiation measurement system. Temperature measurement and control system are developed. The range of temperature controlled is from -100 to 125℃ and the precision controlled is ±1℃ at high temperature, ±3℃ at cryogenic temperature. Experiment about relationship between heavy ion single event upset cross-section and temperature is performed on semiconductor memories and the relationship is first achieved in China.更多还原
