 Sun Jul 31 13:43:56 2016, Sarah, Alpha spectra 
|
Pulser set to 100 pps.
Shaping amp:
Gain: 1x1.0x50 |
|
Thu Jul 28 16:00:43 2016, Sarah, List of to-dos
|
Process alpha data
- Compare pulser width and alpha width to calibration spectra (shaping amp with 1us and gain 50x)
- Does photodiode data process OK or is it a problem with the oscillations? |

Mon Oct 12 12:07:24 2015, Sarah Lonsdale, 05/10/15 Changes to DAQ settings
|
Note that detailed DAQ information available from project-ntof.cern.ch erunbook ear2.
As a rough guide: |
|
Mon Oct 12 12:04:51 2015, Sarah Lonsdale, 05/10/15 Photo of detector distances and layout 8x
|
Fairly self explanatory, note that images with time-stamps before 13.08.29 were taken before fitting the o-ring on the flange and therefore lateral positions
will be different to photos after 13.08.29. Individual detector heights were not changed. |
