207Bi source threshold tests |
|
|
We have dismounted the AIDA stack and bPlast and realigned the cables so that they can fit into the adapters.
The plan for the next couple days is the following:
- Alignment -- done
- Remount cable -- done
- Fix position w/o bPlast mounted -- done
- Remount bracket for the last stage -- done
- Remount AIDA 1 & 2 and the 207Bi source with the source holder -- done
- Mount the snout and take data -- we wait till next week Monday when the heat exchanger is active again. (ongoing)
The current setup at the end of work is that the snout is mount with a bPlast (uncabled) and 2 AIDA layers at the regular spaced position with a 207Bi source down stream, as can be seen in the previous elog. The source is ~1 cm away from the middle AIDA wafer.
Currently what is cabled:
- Signal out from the detector
- Bias daisy chain
Still to be cabled:
- HV cable
- Grounding
- Pulser
Additional info on the source position:
- the source is at ~9.6 mm distance from the downstream detector
- the source is placed at the centre of the middle wafer: 12.25 cm in x, 4.75 cm in y
- the radius of the source is ~1.5 mm |
