Abstract

REMIR is a NIR camera mounted on the REM telescope at ESO-La Silla Observatory. Soon after its installation in 2003, the REMIR camera went through a series of cryogenics problems, due to the bad functioning of the Leybold cryocooler Polar SC7 and we were forced to change drastically the cryogenics of REMIR, going from cryocooler to LN2, via an ad-hoc modified Continuos Flow Criostat, a cryogenics system developed by ESO. Today, the availability of new generation small cryocoolers, in our case the Sunpower CryoTel GT AVC, allowed us to change again and come back to the original cryogenics for the REMIR camera. The system has been assembled and intensively tested at ESO and at INAF-OAR premises, then it has been mounted on the REMIR camera and tested at working condition. In this paper we report the details and results of the project.
