“…The system was also evaluated from 300 to 80 K in a special test dewar 9 and yielded a mean apparent thermal conductivity of 6 x 10-7 Wcm-1 K-1 which corresponds to a radiation heat transfer factor of 5.8 x 10-1 wcm-1 K-1 for a four blanket assembly.…”

“…A model post, instrumented with temperature sensors, was installed and evaluated in a specially configured heat leak measurement dewar. 5 The post ends were at 300 and 4.5 K with intercepts at 80 K and 10 K. The heat intercepting approximates "ideal" conditions since it provided thermal contact between the intercept rings and the heat sinks around the entire perimeter of the rings. The heat flow to 4.5 K was measured by means of heat leak meter.…”

A support member for superconducting magnets and other cryogenic devices has been designed, fabricated and structurally and thermally evaluated. The member is a cylindrical .post constructed with fiber reinforced plastic (FRP) tubing and having metallic heat intercepts and end connections. All FRP to metal connections are made by mechanical shrink fitting and do not employ adhesives or fasteners. The post can operate in tension, compression and flexure or in combinations of these loads. The details of the design and construction are enumerated. Structural performance has been measured in tension and compression ~t 80 and 300 K and in flexure at 300 K. Creep effects on the shrink fit joint reliability are being evaluated. Thermal performance has been measured for a post with ends at ~.5 and 300 K and with heat intercepts at 10 and 80 K. The measured performance has been compared with the analytical predictions. Full scale, working, prototype posts have been successfully'utilized in several model cryostats for the Superconducting Super Collider dipole magnet development program.

“…Thermal performance measurements were conducted in a Heat Leak Test Facility. 4 The support assembly was installed in a helium dewar in much the same way it is installed in a magnet cryostat. Each shield is cooled by internal cryogen lines and the top of the support is attached to an LHe vessel.…”
