Title: Convergence electron impact type ion source
Inventor: WATANABE FUMIO
IPC: G21K1/00
Filed: 1983-10-14
Abstract: PURPOSE:To increase the production rate of ions by outwardly expanding the meshy area of the anode of an ion source for a device such as a mass spectrometer and installing a cathode at the approximate focus of an electron lens formed by the expanded meshy area. CONSTITUTION:A cylindrical anode 1 has an outwardly expanded electron-permeable grid-like or meshy area 1'. An annular hot cathode 2 is placed at the approximate focus of an electron lens formed by the effect of electric field produced by the meshy protruding surface. After that, an electron beam diaphragm electrode 3 is placed between the anode 1 and the cathode 2, thereby constituting a convergence electron impact type ion source for a device such as mass spectrometer. Because of the above constitution, parallel electron beams traveling from the expanded grid 1' into the anode 1 come out from the opposite side of the anode 1 before being concentrated on the hot cathode 2 and reflected by it. After that, the reflected electron beams are attracted by the anode 1 thereby repeating the same movement. Accordingly, it is possible to greatly increase the production rate of ions.

Abstract: PURPOSE:To house a permanent magnet and a driving disk in a small space and to improve responding performance by cylindrically constituting the permanent magnet magnetized in a diameter direction and arranging a pair of driving coils in a arc- shaped symmetrically to the axis passing the center of the permanent magnet so as to surround the permanent magnet with a void between. CONSTITUTION:For driving coils 12 and 13, the side facing the side of a permanent magnet 10 is bent in the shape of an arc, and these coils are arranged symmetrically to a Y axis shown by a dotted line passing through the center of the permanent magnet 10 and is vertical to a steel plate 18 for detent torque. Then, the permanent magnet 10 is positioned surrounded near the driving coils 12 and 13. Therefore, since the driving coils 12 and 13 are close to the permanent magnet 10, the effective line ring lengths of the driving coils 12 and 13 are prolonged. On the other hand, when the magnetism of the permanent magnet 10 is changed in the turn of the permanent magnet 10 after applying driving pulses to the driving coils 12 and 13, a current flows in the same direction and therefore, a time for braking the permanent magnet 10 is shortened. Thus, the space is reduced and a coupling coefficient (torque constant) between the driving coils 12-13 and the permanent magnet 10 is increased to attain a high-speed response.
