LogBook on the CODA data acquisition, at CUA
| Run Number | Date | User | PMT | High Voltage | Experiment | Description and observations | Image |
|---|---|---|---|---|---|---|---|
| New HV module (VME CAEN V6533N) installed. Scan setup rechecked for bad contacts. Restarting scan project... | |||||||
| 1224 | 10/01/2013 | Marco | Blast | -1.800 (VME) | Gain | First test to analyze calibration. LED flashing with very low intensity at 1.075kHz. No SEP can be seen. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 1226 | 10/02/2013 | Marco | Blast | -1.800 (VME) | Gain | Light intensity turned to zero (see only pedestal). | File:1226.png |
| 1227 | 10/02/2013 | Marco | Blast | -1.800 (VME) | Gain | Low light intensity, but still too much. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 1228 | 10/02/2013 | Marco | Blast | -1.800 (VME) | Gain | Even lower light intensity. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 1231 | 10/07/2013 | Marco | Blast | -1.800 (VME) | Scan | Testing LED intensity to start scan run (LED in the center of PMT). | File:1231.png |
| 1232 | 10/07/2013 | Marco | Blast | -1.800 (VME) | Scan | Scan PMT with LED with pulse width 5 and intensity 7. We can conclude that (a) the PMT is not centralized, (b) the scan device got stuck at some point and (c) I forgot to put Mu-Metal shielding. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 1233 | 10/08/2013 | Marco | Blast | -1.800 (VME) | Gain | Run to recheck PMT gain after scan. | File:1233.png |
| 1234 | 10/09/2013 | Marco | Blast | -1.800 (VME) | Scan | Light intensity reajusted. Checking if it was okay, in the center of PMT. Changed a little light intensity after this check. | File:1234.png |
| 1237 | 10/09/2013 | Marco | Blast | -1.800 (VME) | Scan | Scan PMT with LED with pulse width 6 and intensity 7. No Mu-Metal, just checking if Scan device will get stuck again. | File:1237.png |
