Ion gauge operation
WebA hot cathode ionisation gauge comprises three electrodes: a filament, grid and collector. Electrons are produced from the filament by thermionic emission. A positive potential on the grid attracts the electrons away from the filament, causing them to oscillate through the fine structure many times, until eventually they collide with the grid. WebThe hot-filament ionization gauge, sometimes called a hot-filament gauge or hot-cathode gauge, is the most widely used low-pressure (vacuum) measuring device for the region from 10 −3 to 10 −10 Torr. It is a triode, with the filament being the cathode .

WebWhen installing an ion gauge, note that if placed near the pump, the pressure in the gauge may be considerably lower than in the rest of the system. If placed near a gas inlet or source of contamination, the pressure in the gauge may be higher. If an unshielded gauge is placed near an electron beam evaporation source or used in a
Web1 okt. 2024 · Briefly, the ion current in a hot cathode ionisation gauge will be given by the expression (1) I i = I e ⋅ S ⋅ p where I e represents the electron emission current, p the gas pressure and S a constant commonly named sensitivity [ 7 ]. This quantity characterizes the gauge in terms of its efficiency in ionizing and collecting the created ions.
