<p>We started the acquisition via CoMPASS with one CeBr (90) and the HPGe. The germanium was already cooled at 80K with a power of <strong>90W</strong>. The CeBr HV was already applied from NHQ 202M bias supply, channel A, HV = +650V.</p>
<p>We applied the HV to the germanium on 5/6/23, from <strong>Ortec</strong> 660 dual bias supply borrowed from gas target, channel B, HV = +4900V, Bias shutdown connected.</p>
<p>Attached a picture of the baseline in the evening, before leaving the lab.</p>
<p>-----------------------</p>
<p>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 -> <strong>172.17.5.149)</strong>. To connect from lunaserver, lauch <strong>Remmina</strong> and select <strong><strong>lap2</strong>-depalo</strong>. Here, the CoMPASS project is located in /home/Compass/projects/23Na_target_tests.</p>
<p>We have also created the folder on lunaserver in <em>/home/luna/Shared/Data/23Na_target_tests</em>, where we copied from <em>/home/luna/Shared/Data/16O_prompt</em> the scripts required for possible binary conversions.</p>
<p>We are using three channels for the acquisition:</p>
<ul>
<li>Ch. 1: scintillator CeBr 90</li>
<li>Ch. 2 : GeBo + pulser</li>
<li>Ch. 3: Pulser</li>
</ul>
<p>Pulser module BNC Model 9010 with following parameters:</p>
<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>
<p>We left an overnight background run (run_1).</p>
