Abstract : Two DC voltage supplies are needed for the double focussing mass spectrograph, an accelerating voltage of up to 30,000 volts and a deflecting voltage of up to 3500 volts. A very convenient 35 kv high voltage supply is illustrated. It is mounted in oil in a welded steel case. The 35 kv transformer is rated at 10 ma and was tested at 25% overvoltage. The secondary is 26,000 ohms and will stand shorting. Neither end is grounded and the mounting will stand 80 kv. Placing the condenser across the output caused electrical break-down in the bakelite mounting brackets and Mykroy had to be used. The special 8.5 volt, 14 amp filament transformer is insulated from the high voltage transformer. The rectifier is a KR-6, GE-X-Ray Kenotron.
