Abstract
The effect of magnetic field on drift velocity was measured in a wire chamber with an hexagonal cell geometry and an argon-ethane (50:50 by weight) gas mixture. Using cosmic ray tracks, the dtift time to distance correlation was studied as a function of magnetic field strength. Particular attention was paid to the corrections due to differing track entrance angles and differing angles of the magnetic field direction with respect to the wire axis. Spatial resolutions better than 180μm were achieved for field strengths up to 1.5 Tesla and angles between wire and field direction ranging from 0° to 30°. An argon-ethane mixture diluted with 60% helium showed less sensitivity to magnetic field effects, and only slightly worse resolution.
