Single Magnet Test Results of the First EBT-P Development Magnet
The first development coil (D1) for the ELMO Bumpy Torus Proof-of-Principle (EBT-P) machine was successfully tested1 in a large “bucket” dewar — the “open dewar test”. Since then, it has been welded closed and installed in an individual dewar by a McDonnell Douglas/General Dynamics magnet development team. During the open dewar test, the bath contained 500 to 600 L of liquid helium surrounding the coil. In contrast, there is only a volume of about 15 L left for helium inside the individual dewar. This, plus the heat load introduced by the support structure, changed the cryogenic environment of the coil.
