Abstract :
A description is given of an experimental setup designed and constructed at IREQ for the study of gas discharge phenomena occurring under the influence of high voltage. The compact installation provides a facility to carry on avalanche-type and breakdown studies under well-defined conditions. After emphasizing technical considerations necessitated by the simultaneous presence of a variety of constraints such as a temperature-controlled environment (down to -50°C), an absolute experimental pressure ranging from ultrahigh vacuum to a few bars, and applied voltage up to 200 kV DC, the authors examine details of the implemented measures. The experimental setup displays several outstanding features; particular attention is given to the high-voltage bushing and a specially designed HV photocathode
