| 英文摘要 | n this paper we describe a hihg0 frequency pulse tube cryocooler used in a superspectral imager to be launched in 2020. The superspectral imager is a field-dividing optical imaging system and uses 14 sets of integrated IR detector cryocooler dewar assembly. For the requirements of less heat loss an smaller size each set is highly integrated by directly mounting the IR dectector's sapphire substrate on the pulse tube's cold tip and welding the dewar's housing to the flange of the cold finger. Driven by a pair of moving magnet linear motors the dual-opposed piston compressor of the croycooler is running at 120Hz. Filled with customized stainless screens in the regenerator the cryolooler reaches 8.1% carnot efficiency at the cooling power of 1W@80K with 34Wac input power. |
