<p>Optimised motor motion during run R58</p>
<p>Moved 2 mm in (20.3 potentiometer)</p>
<p>29.47 potentiometer</p>
<p>36.5 potentiometer</p>
<p>(started moving pneumatic)</p>
<p>64.36 potentiometer</p>
<p>74.03 potentiomater (servo in by 10 mm)</p>
<p> </p>
<p>Moved in, collected counts for 5 minutes, moved out, waited for re-injection.</p>
<p> </p>
<p>20.3 - 400 counts on the Rutherford peak, bins 125-131 on lowEnergyExTotalDSSD0</p>
<p>20.47 - 646</p>
<p>36.5 - 827</p>
<p>64.36 - 3900</p>
<p>74.03 - 10040</p>
<p> </p>
<p>Based on Rutherford rate ratio, estimated we are 40-50 mm away from interaction point, i.e. beam roughly 1-2 cm on outer half of ring which may be consistent with BPM measurement in YR08</p>
<p><br />
Decided to use 74.03 mm for data collection.</p>
<p>Started data acquisition on R59 at 17:27</p>
<p>Beam 3E7 at injection, 600 second storage, 3 second between cycles</p>
<p>Target pressure 1.3E12 based on 8.21E18 x S1=1.6E-8</p> |
