Description
The spatial resolution of the time projection chamber at TRIUMF has been investigated. The best resolution, sigmaapprox.=200 μm, occurs at the minimum drift length and for an optimum track to anode crossing angle determined by the magnetic field. The resolution worsens for tracks crossing at larger or smaller angles and for longer drift lengths. The observed resolution is quantitatively reproduced by considering the diffusion of the drifting electrons, the track to anode crossing angle, ExB effects near the anode wire and the discrete nature of the ionization process.
