WebThis manual lists the instructions for the users of the 571 Ionization Gauge Tube, with particular reference to the notions relating to safety, operation and first level maintenance, limited to maintenance operations for which the user is responsible. 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.
NGC3 Ion Gauge Controller with Active Gauge Input
WebThe controller can operate two Ion Gauges sequentially, two AML Pirani Gauges and one Active Gauge-head via a standard RJ45 jack. Four power relays for process control are provided as is an internal thermocouple amplifier for bakeout control. WebFor pressure measurements in the UHV range.The idea of the ion gauge is to ionize the rest gas and to measure the pressure via the ion concentration. The operating principle is illustrated below. A hot filament emits electrons which are accelerated to go inside inside a cylindrical wire cage. iron gate emporium birch run
PVCuni/PVCduo Ion Gauge and Vacuum System Controller
WebThe Bayard-Alpert ionization gauge (BAG) was first described in 19501. Modern versions of the gauge have preserved most of the basic elements of its original implementation. Standardization of the BAG design has made it possible for vacuum equipment manufacturers to produce generic ion gauge controllers, such as the IGC100, Webionization gauge for pressure measurements under 10-3 Torr. There are currently two competing ionization gauge technologies to choose from which are viable means for pressure measurements between 10-2 and 10-10 Torr: 1. In the hot cathode gauge (HCG) ionizing electrons from a thermionic cathode are 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 iron gate developer
