<p>We start a new run: beam is ok, target density ok, detectors are moving in-out periodically.</p>
<p>Cooler voltage setpoint 1105.7 V</p>
<p>Attachment 8 - beamcalc with actual values</p>
<p>Next entry - beamcalc with set values</p>
<p> </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 1.7e+7 particles.</p>
<p>Target density ~6e11 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>6:30</p>
<p>Noticed a small spike in all leakage currents, see attachment 1</p>
<p>6:50</p>
<p>all checks ok!</p>
<p> </p>
<p>07:40</p>
<p>All checks are Ok!</p>
<p>Aida 10 shows sometimes higher statistics.</p>

<p>All checks are Ok!</p>
<p>Aida 10 shows sometimes higher statistics.</p>
<p> </p>
<p>10:00</p>
<p>Checks OK.</p>
<p>Compression works OK.</p>
<p>Moved to run 23. Now moving RIGHT hand side detectors instead of LEFT hand side.</p>
<p>Motion 37.96 mm -> 83.69 mm</p>
<p>Left arm stationary at 18.86 mm</p>
<p>Planning to change energy around lunch.</p>
<p> </p>
<p>11:35</p>
<p>Parameters are OK! Tragte density dropped down a bit: ~6e11 at/cm2</p>
<p> </p>
<p>12:35</p>
<p>Parameters are OK! Tragte density dropped down a bit: ~1e12 at/cm2</p>
