Nonmagnetic ionization gage consisting of quadrupole lens systems excited at HF, discussing electron focusing during operation
The ionization gage described consists of separate ionization and collector regions connected at an exit area with a modulator electrode. In addition to the standard modulation function, the modulator in this location yields a suprising increase in collector current, apparently due to improved focussing and extraction of ions from the ionization region.

Effects of electron surface interaction in ionization gauges
A study was conducted to investigate the response of the gauges to ionization in the gas and to discover, if possible, how the circuitry could be modified to make the system operable over a wider range of operating conditions. Shock wave velocities in the range from 3.5 to 27 km/sec were used in the studies. The electronic circuit developed is capable of producing a trigger pulse at a given voltage level across the gauge pins.
