Planned tests
- High Voltage plateau
We will plot the cosmic count rate as a function of HV. We will do this using the Ar-CO2 87%-13% gas mixture. + take a gallery of pulses at each HV point. -- Estimated time: 1 day
- (absolute) Gas gain
Source measurement using Sr-90 (e-) or 55-Fe (X-rays) (if we have it) / or using cosmic rays? -- Estimated time: 1 day
- Dynamic range + amplitude distributions
1 week measure with horizontal chamber + 1 week measure with tilted chamber. For amplitude distributions we need to have modified shapers. -- Estimated time: 2 weeks
- Collection of gallery of pulses
I found 4 pulse galleries, measured directly after the pre-amplifier made by Gerard when he was here, they are shown below:
