LogBook on the CODA data acquisition, at CUA
| Run Number | Date | User | PMT | High Voltage | Experiment | Description and observations | Image |
|---|---|---|---|---|---|---|---|
| 909 (part 2) | 08/06/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | This is the constant DC signal that is used to track any movement in the gate for the prototype. Notice the small patch of events above the main pedestal. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 910 | 08/06/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | 9cm Aerogel run in the dark-box. Using separate HV sources. Tracker still shows two patches of events above the pedestal. Notice large error on fit of signal peak. Npe~9.4 | Error creating thumbnail: Unable to save thumbnail to destination

| 911 | 08/06/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | 8cm Aerogel run in the dark-box. Using separate HV sources. Tracker still shows a patch of events above the pedestal. Npe~7.7 | Error creating thumbnail: Unable to save thumbnail to destination
|
| 911 (part 2) | 08/07/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | This is the constant DC signal that is used to track any movement in the gate for the prototype. Notice the small patch of events above the main pedestal. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 912 | 08/07/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | 7cm Aerogel run in the dark-box. Using separate HV sources. Overnight run. Tracker: about 3 patches of signal above pedestal. Signal: mostly one signal peak (second very small patch at ~400 seems more like trailing peak). Npe~6.8 | Error creating thumbnail: Unable to save thumbnail to destination

|
| 913 | 08/08/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | 6cm Aerogel run in the dark-box. Using separate HV sources. 6 hour run. Seems to be too few data points and therefore a bad fit to the signal peak. Run 914 is the same but for a longer time. | Error creating thumbnail: Unable to save thumbnail to destination

Notice the small patch of events above the main pedestal. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 914 | 08/09/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | 6cm Aerogel run in the dark-box. Using separate HV sources. Tracker: very small patch of signals between 400 and 600. Npe~6 | Error creating thumbnail: Unable to save thumbnail to destination
|
| 914 (part 2) | 08/09/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | This is the constant DC signal that is used to track any movement in the gate for the prototype.

|
| 915 | 08/13/2012 | Laura | 9650 (BLAST) | -1.8 | Prototype Testing (Cosmic) | 5cm Aerogel run in the dark-box. Using separate HV sources. Notice small number of events across whole ADC spectrum and large overflow channel peak. | Error creating thumbnail: Unable to save thumbnail to destination

| 936 | 08/20/2012 | Marco | 60158 (HMS) | -1.810 | PMT Scanning | Scanning setup changed. Since the optical filter was broken, it was reglued to the reference PMT. LED connector was improved, reducing chances of bad connection. Doubt about the quality of the Signal cable. Scanning for test of the setup. Pulse pot high 7.5 (at +5V) and keep width 4 (at 15ns). Scanning with 10x10x1k. Reference PMT (Ref_936). | Error creating thumbnail: Unable to save thumbnail to destination
|
| 937 | 08/20/2012 | Marco | 60158 (HMS) | -1.810 | PMT Scanning | Running a detailed scan to check setup. Same configuration as above, just changing spacial resolution: 100x100 matrix with 1k points in each position. (Ref_937). Perhaps signal cable has a bad contact. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 938 | 08/21/2012 | Marco | 60158 (HMS) | -1.800 | PMT Scanning | Same as run #937. Exchanging Signal cable with Trigger cable, to analyze the suspect of a bad contact in the Signal cable. Reference PMT: (Ref_938). Run stop before conclusion. | Error creating thumbnail: Unable to save thumbnail to destination
|
| 939 | 08/21/2012 | Marco | 60158 (HMS) | -1.800 | PMT Scanning | Same as run #938. Reference PMT: (Ref_939). | Error creating thumbnail: Unable to save thumbnail to destination
