A detailed study of streamer chambers

This thesis describes the construction and operation of a neon helium streamer chamber. The design of a fast high voltage pulsing system, which utilises the energy stored in a water dielectric capacitor and has been charged by a Marx generator, is discussed in detail. The performance of the system is examined and its characteristics are investigated particularly where they are relevant to its use as a particle detector. A statistical model has been programmed and is used to predict and interpret the results obtained directly from the streamer chamber. The agreement between theory and practice is found to be good. The spacial accuracy of the device is measured and its resolution estimated. No significant sensitivity to ionisation has been found but a time resolution of less than 1 µsec appears feasible. Suggestions to improve the streamer chamber system are made and proposals for a second generation streamer chamber are given.
