Oscilloscope mass spectrum display for the dupont 491 mass spectrometer

Robert J. Cotter

Research output: Contribution to journalArticlepeer-review


A repetitive scanning circuit has been designed for displaying a portion of a mass spectrum on an oscilloscope. The system described here makes use of the ESA and accelerating voltages generated by an INCOS/Finnigan interface for the Dupont 491 double-focussing mass spectrometer, but may be adapted to other configurations.
