<p><strong>Run 21 running</strong></p> <p>26/05/2025 19:42 p.m.</p> <p>We start a new run with real data taking condititon: beam is ok, target density is 1.1e12 cm-2, detectors are moving in-out periodically.</p> <p>Cooler voltage setpoint 1105.7 V.</p> <p>Beam energy = 1.95 MeV/u</p> <p>Right arm at 19.80 mm</p> <p>Left arm IN at 77.56 mm (OUT 32.53 mm)</p> <p>vertical beam position 0.0 mm</p> <p>horizontal beam position -3.5mm</p> <p>Beam intensity 2.2e+7 particles.</p> <p>Target density ~1.1e12 at/cm2</p> <p>Target temperatures: T1=31.5 K T2=35.2 K</p> <p>Beam cycle set to 10 seconds.</p> <p>All check are Ok!</p> <p>21:44</p> <p>All check are Ok!</p> <p>23:10</p> <p>Data rate to disk ~300 kB/sec</p> <p>All checks OK</p> <p>ADC disk Items #6 and ADC data items screenshots - attachments 5 and 6</p> <p>Target density has dropped slightly to 7e11 at/cm2. This is fine with lithium due to beam lifetime constraints.</p> <p>00:43</p> <p>All checks OK</p> <p>01:52</p> <p>All checks are OK,</p> <p>Attached spectra (attachment 7 and 8).</p> <p>target pressure seems to be back at ca. 1E12 at/cm2</p> <p>3:27</p> <p>All checks good.</p> <p>target pressure went down to 5E11 at/cm2 for a while, then back up to ca. 9E11 at/cm2.</p> <p>4:49</p> <p>All checks good</p> <p>Rates higher on aida10 and aida4 (see attachment 9), monitoring. It is not consistently high but for example aida10 goes 222->20000->300->11000. It seems to follow the detector movement (higher rates when detector are IN)</p> <p>Data rate to disk ~370kB/s.</p> <p>Spectra attached in 10-11.</p> <p>5:11</p> <p>Still flickering. Attachment 12 with rates.</p> <p>Data rate to disk around ~400 kB/s</p> <p> </p> <p>05:30</p> <p>DAQ has crashed. All statistics on aida read zero. No data through the merger or tape server.</p> <p>Stopped tape server and then Run control STOP. Most FEEs did not respond to the command and continued to read going and some undefined. Reset aida servers and reloaded webpages. Same status. Have to power cycle.</p>
