<p>We start a new run with real data taking condititon: beam is ok, target density is 5e11 cm-2, detectors are moving in-out periodically.</p>
<p>Cooler voltage setpoint 1128.55 V.</p>
<p>Beam energy = 1.99 MeV/u (from HKR)</p>
<p>Attachment 1 - beamcalc with set values</p>
<p>Attachment 7 - beamcalc with actual values</p>
<p> </p>
<p>Left arm at 18.86 mm</p>
<p>Right arm IN at 83.69 mm (OUT 37.56 mm)</p>
<p>vertical beam position 0.0 mm</p>
<p>horizontal beam position -3.5mm</p>
<p>Beam intensity ~2e+7 particles.</p>
<p>Target density ~5e11 at/cm2</p>
<p>Target temperatures: T1=31.5 K T2=35.1 K</p>
<p>Beam cycle set to 10 seconds.</p>
