Omegatron mass spectrometer

The Omegatron Mass Spectrometer is uniquely suited for use as a residual gas analyzer for electronic vacuum devices. This has been evidenced by its increased usage as an attached appendage for measuring the gas ambients in traveling wave tubes, cathode ray tubes and receiving tubes. In essence, the Omegatron is a vacuum tube which operates on the same principle as the cyclotron. Gas molecules ionized by electron bombardment are accelerated in a cycloidal path under the influence of magnetic and RF fields. Under conditions of resonance, ions with a certain mass-to-charge ratio are collected and the resultant output recorded as one peak of a gas spectrum.
