1 Study of Chinese oil-less chamber

2 Construction details 350 X 350 X 30 mm Insulating surface
Gas connections

3 Construction details Signal pick-up strips Gas/HV terminals Back view
Front view

4 HV test result Top gap V-I characteristics seem to be OK till about 3000V (Current: 0.09A) Current fluctuates beyond this voltage Bottom gap Current, a factor of 10 higher than the top gap

5 Construction details Double-gap Gap sizes
Bottom: 320 X 320 X 6.6 mm Top : 290 X 290 X 6.6 mm Pick-up strips: 13; Strip width: 22 HV contacts made through Cu tapes stuck on graphite surfaces and terminated on gas nozzles!
