Drift and proportional tracking chambers
Abstract
The many techniques exploited in constructing tracking chambers, particle detectors which measure the trajectories and momenta of charged particles, are discussed. In high energy interactions, the final states are dominated by closely collimated jets of high multiplicity, requiring good track-pair resolution in the tracking chamber. High energy particles deflect very little in limited magnetic field volumes, necessitating good spatial resolution for accurate momentum measurements. The colliding beam technique requires a device easily adapted to full solid angle coverage, and the high event rates expected in some of these machines put a premium on good time resolution. Finally, the production and subsequent decays of the tau, charmed and beautiful mesons provide multiple vertex topologies. To reconstruct these vertices reliably requires improvements in spatial resolution and track pair resolution. The proportional counter and its descendant, the drift chamber, are considered as tracking chambers. The physics of this device are discussed in order to understand its performance limitations and promises.
