Claims

[Claims for Utility Model Registration] 1. A trap cell placed in a highly vacuum state and in a magnetic field in a fixed direction, and an electron beam irradiation means for applying accelerated electrons to gas molecules in the trap cell. , is equipped with a signal generating means that applies an alternating electric field to the trap cell, causes the ions generated by electron bombardment to move in a circular motion in the magnetic field, and traps them in the cell using this magnetic field and the electric field applied to the trap cell, and traps them in this state. In an ion cyclotron resonance mass spectrometer that detects ions by applying an alternating current signal to a cell and detecting the response of ions in an alternating electric field, a filament and a grid are placed on the electron emitting side of an electron beam irradiation means. Hits the,
By fixing the filament and grid holder together with an insulator block, closely fixing a plate-shaped grid to the surface of the grid holder, and fixing this block to the plate of the trap cell, the filament and grid can be fixed together. and an ion cyclotron resonance mass spectrometer characterized in that the positional relationship of the plates is fixed. 2. Scope of Utility Model Registration Claim 1, in which a reference surface and a reference end surface perpendicular to the reference surface are set on the block, and each of these surfaces is brought into close contact with the surface and edge of the plate constituting the trap cell, respectively. Record! mass spectrometer. 3. The mass spectrometer according to claim 1 or 2, wherein the grid is made of a metal plate in which a large number of holes are formed at regular intervals in the vertical and horizontal directions.
