We started the acquisition via CoMPASS with one CeBr (90)  and the HPGe. The germanium was already cooled at 80K with a power of 90W. The CeBr HV was already applied from NHQ 202M bias supply, channel A, HV = +650V.

We applied the HV to the germanium on 5/6/23, from Ortec 660 dual bias supply borrowed from gas target, channel B, HV = +4900V, Bias shutdown connected.

Attached a picture of the baseline in the evening, before leaving the lab.

-----------------------

The DAQ from solid target is connected to the new Intel NUC mini-PC, located below the VME crate. It is possible to connect remotely to such PC using the RDP protocol (IP address -> 172.17.5.149). To connect from lunaserver, lauch Remmina and select lap2-depalo. Here, the CoMPASS project is located in /home/Compass/projects/23Na_target_tests.

We have also created the folder on lunaserver in /home/luna/Shared/Data/23Na_target_tests, where we copied from /home/luna/Shared/Data/16O_prompt the scripts required for possible binary conversions.

We are using three channels for the acquisition:

• Ch. 1: scintillator CeBr 90
• Ch. 2 : GeBo + pulser
• Ch. 3: Pulser

Pulser module BNC Model 9010 with following parameters:

• Amplitude 50 mV
• Frequency 24 Hz
• Delay 1 us
• Width 1 us
• Rise Time 0.05 us
• Fall Time 5 us
• Polarity: positive
• No attenuation

We left an overnight background run (run_1).
