Design and Construction of a High Stability Magnet Power Supply for the (Varian Mat SM sub 1 -BF) Mass-Spectrograph

摘要

The report deals with the redesign and replacement of the power supply of the SM sub 1 mass-spectrograph. The new unit does not use electron tubes but popular semi-conductors. The magnet is made of eight identical coils connected in series, each with a resistance of about 560 Ohms. The coils were connected in parallel, thus reducing the maximum drive voltage to some 15O V. The total resistance became about 70 Ohms at 2 A max. The stability requirements for the high precision mass spectrography are also discussed. (Atomindex citation 16:058543)
