Webgas is cooled first by the 1st stage of the refrigerator and then by the 2nd stage. The cold gas flows from the 2nd stage heat exchanger through the transfer line into the microscopy cryostat. The ‘cold finger’ in the microscopy cryostat is cooled by the cold gas stream. The dry scroll pump returns the gas to the refrigerator cryostat. WebCRYOSTAT DESIGN A commercial 2-stage PTC (CRYOMECH, PT405-RM)4 is used to precool the DR and its 1K-stage. The temperature sensor for the 1st stage was a Pt1000 sensor5, for the 2nd stage a Cernox resistor6 is used. As reported before, a small PTC (0.5 W at 4 K) is used to minimize vibrations and acoustic noise. Web2 Tank for 2nd Stage Saturn V June 2024 Lecture 7 Thermal Insulation & Cryostat Basics- J. G.
