Energy Doubler Refrigeration System
The design concept of a central liquefier supplying satellite stations as well as failure nudes will be discussed. Performance data will also be presented.
Two cell doubler systems test
A superconducting magnet system testing area has been constructed above ground at the B12 location of the Fermilab main accelerator which facilitates the testing and development of superconducting magnet systems prior to committing their design to the full scale production Of the Doubler accelerator. The test results and operating experience of this system will be reported.
A Magnetically Operated Cryogenic Valve
The usual cryogenic valve is a modification of a conventional valve. As such, these valves frequently have a number of drawbacks including large heat leak, large cold mass, leakage, etc. This paper describes a valve which has been specifically designed, constructed, and tested for use in small liquid-helium transfer lines. It is welded into a straight section of transfer line and increases the cold mass by the equivalent of one foot of line. The valve is of welded, all-metal construction and has a modified ball-and-cage design. A standard valve solenoid is used for actuation and is mounted outside the vacuum space.
