Abstract : A calori meter-type gauge was constructed using a pair of twisted number 44 formvar covered copper leads. The twisting minimized the induced voltage to a tolerable level (of the same order of magnitude as the heat transfer signal) provided the gauge was not in the presence of an ionized gas. The induced voltage was increased so much when a plasma was at or near the gauge that no conclusive evidence could be obtained regarding the question of total containment. It was observed that the heat transfer to the gauge was reduced by more than 80% when the magnetic field was applied. This conclusively showed that the plasma was at least partially contained. No conclusion could be drawn as to whether or not the total heat transfer to the gauge (when the magnetic field was applied) was due solely to the driver gas. (Author)
