Self-modulating ion gauge

A Bayard--Alpert ionization pressure gauge has been modified by shortening the collector wire thereby reducing the x-ray limit from approx.2.5 x 10/sup -11/ to approx.0.6 x 10/sup -11/ Torr. In addition it has proven possible to modulate this gauge and thus make an in situ determination of the x-ray limit without the introduction of a modulation electrode. Thus a self-modulating, low x-ray limit ion gauge has been developed at reasonably low cost and seems particularly suited to the ISABELLE ultrahigh vacuum system.
