| Run Number | Date | User | PMT | High Voltage | Experiment | Description and observations | Image |
|---|---|---|---|---|---|---|---|
| 635 | 05/25/2012 | Marco | 09561 | -1.800 | PMT Scanning | Remove LED, insert another paper attenuator (working now with 2 layers), cut a piece of the blue rubber that protects the LED contacts (trying to make better contact). Increase pulse for pot high 10 (at +5V) and keep width 4 (at 15ns). Scanning with 10x10x1k. Reference PMT (Ref_635) really stable now! Two suspects: the LED must work with 5V for this very fast pulse (don`t know the resistor that is connected in series with it) or the bad contact was fixed. | Error creating thumbnail: Unable to save thumbnail to destination

| 636 | 05/25/2012 | Marco | 09561 | -1.798 | PMT Scanning | Working in the same conditions of run #635. 100x100x1k scanning. Reference PMT signal: Ref_636. Color scale in number of photoelectrons (calibration in run #558). Now the LED is constant! It is important to say that the amount of light (using just two attenuator papers) is big. | Error creating thumbnail: Unable to save thumbnail to destination

| 640 | 05/30/2012 | Nathaniel | 09561 | -1.700 | PMT Gain | I now am running similar tests to the gains tests in runs 556-563. However this time I am using Dark Box 1 instead of Dark Box 2. This will allow systematic error analysis. | Error creating thumbnail: Unable to save thumbnail to destination

| - | 05/30/2012 | Nathaniel | 09561 | - | PMT Gain | Here is the Spreadsheet with all the Data and the plots. It appears that the 2 boxes are very close, they are within ~12% of each other. Not bad? | File:PMT Gain 1.xls |
| -- | 06/7/2012 | Nathaniel | 09561 | --- | PMT Gain | I have completed the full error analysis for the correction factor, the attenuation factor of DB1, and the two Gain measurements (one for DB1 and DB2). I have updated the two excel spreadsheets (PMT_Gain_1.xls and att_fac_darkbox1.xls) I have also used PAW to plot each gain vs HV, as well as both on the same plot fitted with the same line to show close correlation. | Error creating thumbnail: Unable to save thumbnail to destination
