Abstract
Direct mass spectrometry in the production region of collision-dominated weakly ionized argon plasma was demonstrated for omegatron using Gifford-McMahon cryocooled superconducting magnet. A numerical model which included collisional effects was proposed to describe the performance of omegatron. Mass spectrometry was successfully conducted using a high magnetic flux density of up to 2 T and a high pressure on the order of 10-3 Torr. It was found that an increase of the radio frequency voltage applied to the omegatron resulted in enhanced ion spectrum density.
