SILICONE DIELECTRIC GEL CRYOGENIC DETECTOR INTERFACE |
摘要 |
<p>IMPROVEMENT IN A CRYOGENIC DETECTOR TO AVOID VIDEO-FLASHING AND THERMAL FLUCTUATIONS The inherent video noise and video-flashing encountered at the liquid nitrogen boiling point within a cryogenically cooled detector is substantially eliminated by filling any space which might entrap air with a flowable self-sealing silicone gel. The gel is sticky and maintains its adherence to both the cold finger and dewar as it is cooled to cryogenic temperatures without losing its internal self-cohesion. In the illustrated embodiment a two-part gel manufactured by Dow Corning under the trademark SYLGARD 527 is employed. The gel is characterized by being self-sealing to at least a temperature within the range of -60 degrees C. to -100 degrees C. In addition, the gel is thermally stable at all temperatures from elevated ambient temperatures through cryogenic temperatures.</p> |
