Labelled PID plots. Note that the A/Q calibration is shifted by +0.02 units, and Z calibration is offset by about +5.
There was an error in the printouts for Cd isotopes, but the below attachments are corrected.

BB7 is still connected but not biased (same configuration as the previous elog). The channel of the CAEN power supply #0 is connected to ASIC08 and biased
at 100V. The channel of the CAEN power supply #1 is disconnected but still biased at 100V. AIDA04 (chained to AIDA05) is biased via an unshielded
cable to an iseg NHQ 246L power supplied, biased at 100 V with 15 uA. |

This elog is the first reliable. Before, the histograms have not been zero'd
Each test are done and compared for AIDA05.1.8L, compared with the pulser (caracteristics, see attachment1)
Test 1: with HT cables shielded |

Attachment 1: AIDA05.1.8L --> FWHM 75 channels
Attachment 2: AIDA05.1.1L --> FWHM 70 channels; peak of the pulser shifted to the right (red lines on the left: cursor for the 1.8L) |

been connected to the ground via cupper sheets
FWHM: 76 channels (to be compared with the 2 previous elogs 73 channels and 75 channels) |
