Abstrak

In the context of the ATHENA X-IFU Cryogenic AntiCoincidence Detector (CryoAC) development, we have studied the thermalization properties of a 2mm x 2mm SQUID chip. The chip is glued on a front-end PCB and operated on the cold stage of a dilution refrigerator (TBASE < 20 mK). We performed thermal conductance measurements by using different materials to glue the SQUID chip on the PCB. These have been repeated in subsequent cryostat runs, to highlight degradation effects due to thermal cycles. Here, we present the results obtained by glues and greases widely used in cryogenic environments, i.e. GE 7031 Varnish Glue, Apiezon N Grease and Rubber Cement.
