Two particle analyzers, in which fine metal meshes are used, have been developed. One is with a simple and compact-type ion detector. The incident ion is accelerated and releases secondary electrons on the grids of mesh. These electrons are accelerated and detected with a scintillator and a photomultiplier. With this detector, high sensitivity and low noise level of 2×10^<-19> A are obtained even for low energy ions. The other is a two-dimensional display spectrometer. After ionization of incident neutral particles in a gas cell, the resultant ions are separated with a J. J. Thomson's analyzer and are converted to secondary electrons with the grids of mesh. The electrons are multiplied with a channel plate, then accelerated to a phosphor screen, and display parabolic lines on it according to q/m of ions. It has a sensitivity of measuring 10^<-13> A of particle current and mass and energy resolutions of 3%.
