<p>A magnet cartridge (17) and thremal shield (25) are supported by three concentric nested thin wall tubes (33,35,37) from a vacuum vessel (11). The innermost tube (33) of thermal inulating material is affixed to magnet cartridge at one end and supports the first stage heat station (57) at the other. The intermediate tube (35) of heat conducting material transfers the load from the inner tube (33) to the outer tube (37), which is affixed to the vacuum vessel. The intermediate tube also thermally connects the first stage heat station to the thermal radiation shield. The outer tube also supports the thermal radiation shield. All of the tube joints rely on epoxy-bonded threads to provide good mechanical strength, low motion thermal contact resistance, and no relative motion.</p> |
