Abstract:
- This report summarizes some useful data on the transport
characteristics of gas mixtures which are required for detection of
charged particles in gas detectors. The requirements for high
luminosity tracking are stringent and different at low and high
momenta, representing a compromise between a fast gas mixture, small
diffusion properties and having a small Lorentz angle, but high
primary ionization. With the advent of a host of computing programs
available the transport parameters are rather well estimated and
corroborated by experiment. Mixtures of some noble gases with popular
quenchers are considered, with some emphasis on low mass gases. Pure
noble gases for example argon and xenon are also presented with single
photon detection and medical imaging applications in view
respectively.
