Particle Accelerator and High Voltage Machines TIDA 500 STREAMER CHAMBER DEVELOPMENT

ACKNOWLEDGEMENTS The development of the two-meter streamer chamber at SLAC represents the culmination of more than three years of effort involving a large number of people. We have space to mention only a few. the SLAC physicists who participated in the early phases. The streamer chamber program carried out by Drs. D. Benaksas and R. Morrison at Stanford has provided us with the reassuring information that it is possible to operate streamer chambers in high magnetic fields and that it is practical to use these chambers in the photon beams produced by electron linacs. As is clear from the text, we have benefitted considerably from discussions and numerous private communications with J. C. Martin and I. Smith of AWRE in England, both of whom visited SLAC to contribute in this program. G. Schultz were closely involved in the construction, assembly, and testing of the various components and systems; they have shared, on a day-today basis, our numerous frustrations and occasional successes. In addition, we are grateful for the generous help of the shops and the accelerator staff at SLAC. Finally, it is a pleasure to acknowledge the support and encouragement of
