摘要：

The signal-to-noise ratio in mass and ion kinetic energy spectrometers is limited by noise generated from the presence of scattered ions and neutrals. Methods of eliminating this are illustrated with reference to the ZAB-2F instrument manufactured by VG-Micromass Ltd. It is estimated that after the modifications the instrument is capable on a routine basis of measuring peaks corresponding to the arrival of ions at a rate of the order of 1 ion s-l. © 1979.
