N2 - A multichannel high-Tc dc-SQUID based heart-magnetometer is currently under development in our lab. The system is cooled by a cooler that, due to its magnetic interference, has to be sepd. from the SQUID unit. In the present prototype system a closed-cycle gas flow was chosen as the interface between the SQUID unit and the cooler (a Leybold Heraeus RG 210). In this paper the prototype system is shortly described, its thermodn. behavior is considered and simulations are compared with exptl. results. [on SciFinder (R)]
