FAST MAGNETIC FIELD SWEEP

DOI:https://doi.org/10.1063/1.1717128· OSTI ID:4137665
A circuit for producing a magnetic field in a mass spectrometer is described. This field varies in triangular form at a rate of at least 1 cps with a magnitude of 500 gauss above a 1000- to 7000-gauss bias. The circuit uses a Varian V-4012 12-in. electromagnet and two Philbrick USA-3 operational amplifiers in place of the electromagnet's V-2100 power-supply amplifier. Diagrams are given of the circuitry, and some data on the performance of the sweep are tabulated as a function of the peak-to-peak sweep (gauss). (D.L.C.)
