> - 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
