Transit time mass spectrometer

A new type non-magnetic mass spectrometer is proposed, which has a simple electrode strucuture of relatively small size, and operates by high frequency square form pulse voltage. Theoretical results show that this mass spectrometer will have a moderate resolving power of about 70 - 100 and an excellent sensitivity characteristics, especially suitable for a vacuum analyzer. It may be expected that the resolving power may be raised to at least about 300, only by changing the method of operation.
