- Of the two 500 micron detectors from the GELINA setup one has broken bond wires and the other does not show a normal VI response to bias see attachment 1 - The response appears to be ohmic - Instead the two 1000 micron W1 detectors were mounted onto the stand - Both of these bias nicely and show appropriate leakage currents - attachment 2 - The photodiode has been tested and we see the noise decrease as we apply bias - This is our only indication it is working at at its nominal -30V the detector draws 0.00uA of leakage current - The DAQ has been fully setup with 3 ADC modules which is enough for both W1 detectors and the photodiode - Nominal pulse peak widths are around 20keV for all channels - This is without any efforts to ground preamps to amplifiers - One of the preamps we brought out has had two capacitors knocked off it. We have replaced this with a preamp taken from the GELINA chamber. - This preamp is configured with the pins reversed so will require the cable running to the detector to be reversed when we setup the experiment - We are bringing this preamp back to be repaired by the electronics workshop also - The TDC has also been setup for all channels of the W1 detector. Will move this to the mattermost channel once setup Encoding: HTML ELCode plain Suppress Email notification
