33. 50 kV Voltage Isolator for the SPICES Instrument

A unique invention for the SPICES instrument is shown in the picture where a conical thermally conductive voltage isolator was developed to support the floating internal instrumentation “bubble”. The isolator uses a special shield for the triple junction and was tested at 75,000 volts. Three isolators are used to both structurally support and suspend the SPICES bubble at +50,000 volts. A special feature of the isolator is that is also designed to be thermally conductive with each of the 3 isolators capable of conducting 5 watts of heat with a thermal drop of less than 10C. Thus, it is possible to operate the instrumentation bubble at 15 watts while floating at 50,000 volts.
