Physical Data
Connection: 2-3/4", 1" Conflat or KF 40 flange
Envelope: None
Mounting Position: Vertical
Collector: .005" Tungsten
Filament: Replaceable Thoria-coated Iridium or Dual Tungsten (8130)
Grid: Tantalumand Pr/Moly support squirrel cage
Operating Data
Sensitivity for N2: 25/Torr
X-ray Limit: 2 x 10-11 Torr
Operating Pressure: 2 x 10-11 to 1 x 10-3 Torr
Electron Bombardment Degas: 40 Watts @ 500 volts
Resistance Heated Degas: n/a
Bake-out Temperature: 450°C
The ETI Nude Ionization Gauge is a high-sensitivity gauge covering the vacuum range of 1 x 10-3 to 2 x 10-11 Torr (Argon). This tube features replaceable filaments, dual Tungsten or single iridium, and a small diameter-cage tantalum grid on platinum-clad, molybdenum support rods. A .005" - diameter collector is used. This results in a low X-ray limit, sensitive tube, capable of being baked out to 450°C for those applications requiring high-temperature processing.
