Abstract
RECENTLY, the constriction of fairly high pressure discharges by applied radial electric fields has been observed by Kenty1. The discharges, which are very sensitive to electrostatic effects, are of the low current diffuse type in which the ions disappear mainly by volume recombination2. For d.c. fields, annular rings are provided just inside the wall of the tube. The discharge can be greatly constricted by making these rings negative to the discharge, while at the same time the positive ion current per unit length can be measured.
