Combined refrigerators and detecting system using the same

摘要

An electrically cooled detecting system comprises: two or more heat regenerative refrigerators each having a cylinder with a cooling head at its one end; a holder for supporting the two or more heat regenerative refrigerators to dispose the one ends of the cylinders along a certain plane and the other ends of the cylinders on one side of the certain plane; a connector for thermally and rigidly connecting the cooling heads; and a detector being thermally connected to the connector. This system is not necessary to use liquid nitrogen. This system is compact and has a high energy resolution.
