OH | VI curve of 1000micron W1 detectors |
- 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 |

DAQ configuration - attachments 1-9
Setting up CAEN V767 TDC
Note that to perform timing with the leading edge of the input logic signals
you need to select `rising edge' timing.
The following procedure for changing CAEN V767 settings _reliably_ appears
to work:
1) Halt data acquisition
2) From MIDAS Main Menu window select VME Module Control -> CAEN V767
3) From CAEN V767 TDC Setup & Monitor window _de-select_ -> Act on ALL
Modules?
4) From CAEN V767 TDC Setup & Monitor window select the first TDC module
whose setting you wish to change
5) From CAEN V767 TDC Setup & Monitor window select Expert -> Disable Auto Load
6) Change CAEN V767 module settings as required
7) From CAEN V767 TDC Setup & Monitor window select Expert -> Save User
Configuration
8) From CAEN V767 TDC Setup & Monitor window select Expert -> Enable Auto Load
9) Repeat steps 4-8 for any other CAEN V767 TDC modules whose settings you
wish to change
10) From CAEN V767 TDC Setup & Monitor window select Save Setup
11) From MIDAS Data Acquisition Experiment Control window select Setup ->
Setup Everything
12) If you reboot the VME PowerPC CPU do NOT forget to set the TDC(s) in
common stop mode
From MIDAS Data Acquisition Experiment Control window select Advanced ->
Configuration/Test/Debug Frame and confirm the request.
Settings should be:
TDC Mode: Common Stop
TDC Hit Option: all
TDC Referemce: 0 (usually)

N.B. The analog output of the RAL109 shaping amplifier module will not
drive a 50 Ohm load nor a 50Ohm coaxial cable > 20cm.
Always onnect the analog output of the RAL109 shaping amplifier module
to an oscilloscope input with 1MOhm/dc input coupling via an IDC ribbon
cable to Lemo-00 adaptor and a short coaxial cable (0.5ns, say). |
