Cold cables for “dry” cryostats
Modern low-temperature systems increasingly make use of “dry” cryostats whose cooling effect is reached in vacuum solely by direct thermal contact. However, cables and electric wiring may impede the cooling process if they are not coupled thermally at suitable locations between room temperature and operating temperature. At PTB, two new designs have therefore been developed to thermally couple round cables and flat ribbon cables. The heat flow, which propagates through the supply lines to a sensor, can thus be minimized. This is particularly helpful at a temperature below 4 K. (Technology Offers 473 & 483)
low thermal impedance for varying cable sizes
can easily be integrated into existing cryostats
connections are easily disengaged
