A Mass Indicator Using a Vibrating Coil Magnetometer

Abstract

A vibrating coil magnetometer has been developed which provides precise and continuous indication of the strength of a magnetic field. The device is used on a sector mass spectrometer to obtain both visual mass indication and spectra calibration in the mass range of 2–400.

Similarity laws in disordered condensed systems

“…Oscillating magnetometers are widely used for different investigations of magnetic materials (Smith 1956, Foner 1956, 1959, Caldecourt and Adler 1954, but the shortcomings of existing instruments demand regular calibration by reference to a suitable standard. Besides, very often in the case of such instruments the use of the null method is impossible.…”

An analytical treatment of ionization efficiency data for xenon from a pulsed retarding-potential ion source

“…A few mass indicators have been reported for use with mass spectrometers for so:.ie time, however their operation is usually based on rotating coil magnetometers for which the accuracy is limited (42,43). The magnetic response char acteristics of semiconducting crystals suggested their poten tial use as mass indicators for mass spectrometers.…”
