The ignition of a THETA-pinch discharge in a single-turn solenoid is studied in inert and electronegative gases with p=1--1000 torr. A method is developed for calculating the radial and tangential electric fields in the solenoid. The finite dimensions of the gap and the difference between the dielectric constant of the chamber material and the filler gas are taken into account. The electrostatic component of the field is an order of magnitude higher than the induced component in the discharge region. The dielectric constant of the chamber and the thickness of the chamber all affect the electrostatic field in this region. Theoretical and experimental support is given for a mechanism for the ignition of the THETA-pinch. In this mechanism, the discharge starts near the gap of the single-turn solenoid, where the field is strongest; the discharge then spreads in both directions away from the gap along the inner wall of the chamber as an electrodeless grazing discharge.
