Passive Ion Gauge Bayard-Alpert
The AML AIG nude ionization gauge is a high-sensitivity UHV Bayard-Alpert gauge covering the vacuum range of 3×10-11 to 1×10-3 mbar and is intended for electron-bombardment degas. It has an NW35CF flange with in-dividual glass compression seals, closed-end grid and a choice of filament materials.
Features
Wide measuring range 3×10-11 to 1×10-3 mbar
Replaceable twin Tungsten, Thoria or Yttria-coated Iridium filaments
Individual glass compression seal around each feedthrough pin are more economical and
robust than ceramic, resulting in a less expensive and more rugged gaugehead, with the
central collector pin inherently guarded against leakage currents by the grounded bulk of the
flange
The molybdenum grid has a closed-end, light, rigid structure, resulting in high sensitivity. The X-
Ray induced electron desorption current at the collector is minimized by geometry and screening
Connector pins are gold-plated, shrouded and polarized. Gold plating ensures that oxidation
on the air-side cannot occur even after repeated bakeouts
Maximum bakeout temperature 450 °C. Sensitivity 19 per mbar for nitrogen. X-Ray asymptote
3×10-11 mbar
RoHS compliant
