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

We applied the HV to the germanium on 5/6/23, from&nbsp;Ortec&nbsp;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&nbsp;Intel NUC mini-PC, located below the VME crate. It is possible to connect remotely to such PC using the RDP protocol (IP address -&gt;&nbsp;172.17.5.149). To connect from lunaserver, lauch&nbsp;Remmina&nbsp;and select&nbsp;lap2-depalo. Here, the CoMPASS project is located in /home/Compass/projects/23Na_target_tests.

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

We are using three channels for the acquisition:

<ul>
	<li>Ch. 1: scintillator CeBr 90</li>
	<li>Ch. 2 : GeBo + pulser</li>
	<li>Ch. 3: Pulser</li>
</ul>

Pulser module BNC Model 9010 with following parameters:

<ul>
	<li>Amplitude 50 mV</li>
	<li>Frequency 24 Hz</li>
	<li>Delay 1 us</li>
	<li>Width 1 us</li>
	<li>Rise Time 0.05 us</li>
	<li>Fall Time 5 us</li>
	<li>Polarity: positive</li>
	<li>No attenuation</li>
</ul>

We left an overnight background run (run_1).
