Selin | Pulser Test |
The pulser test was performed with a frequency of 500 Hz and with voltage settings of: 2V, 1.6V, 1.2V, 0.8V, 0.6V, 0.4V, 0.3V, 0.2V, 0.1V, 0.05V, 0.025V.
The run was started with calibration settings and then the voltage was changed every 2.5-3 minutes.
From the attached plots, it can be seen that everything is as expected. This means that the pulser multipolarity is consistent with front and back strips, pulser signals are more frequent and the pulser amplitude decreases with decreasing V.
The front and back pulser tests have been done with separate runs and the settings have been reverted to their original values (100 Hz, 2V, pulser is off). |

Selin | Boron-3 Consistency Check |
These are the consistency checks done for Boron-3 sample.
Please note that the back strips for the first run are mismatched due to the settings in DAQ. |

Selin | Boron Spectra Update After Setting Change + Pulser Removed |
Uncalibrated amplitude spectra of Boron (run221188) after the settings were changed, the pulser was removed, and the threshold in the UserInput has been lowered. Both alphas can be seen in the front and back strips. The ratios between the alphas are similar for front (0.066) and back (0.063) strips.
1- Uncalibrated amplitude spectra of strip 2.
2- 1- Uncalibrated amplitude spectra of strip 19. |
