<p>Run 40 continues.</p>
<p>Beam intensity looks OK. Oscillates between just below 2.5e7 and just below 3e7. (attachment 1)</p>
<p>Target density 4.3e11, YR09 pressure 1.54e-10 mbar.</p>
<p>Rates in monitoring code show beam on target.</p>
<p>FEE temperatures all OK - plot over time (attachment 2)</p>
<p>System check OK</p>
<p>Leakage current OK -trending down (attachment 3)</p>
<p>Tape server and merger OK. Merger stats (attachment 4)</p>
<p>ADC data items looks OK, spectrum browser rates OK</p>
<p>Spectrum browser stat (attachment 7 LOG scale) - looks like some HEC were firing previously. Spec browser histograms zero'd to monitor</p>
<p>pn + nn waveforms (attachments 5+6)</p>
<p>Monitoring code energy histograms (attachment 8)</p>
<p>02:40</p>
<p>X2go screen size has decreased further -> cannot see target density but can view beam intensity. Will use ML vac plot to help gauge beam on target</p>
<p>Beam intensity has decreased over the last hour but has now stabilised and is now ~2e7 at injection. Pressure in YR09 has decreased slightly accordingly from ML online but not significantly (still >1e-10 mbar)</p>
<p>Monitoring code rate plots indicate beam on target</p>
<p>All daq checks OK</p>
<p>Will continue to monitor beam intensity</p>
<p>04:14</p>
<p>Ring intensity has increased and appears stable back at 2.5e7.</p>
<p>Target density has slightly decreased to 3e11, ring pressure YR09 stable at 1.5e-10 mbar. I am reluctant to try and move the nozzle while my x2go screen is not 100%.</p>
<p>FEE temps OK</p>
<p>System checks OK</p>
<p>Merger and tape server OK</p>
<p>Rates in all FEEs look OK</p>
<p>Spectrum browser stats (attchment 9) no HEC firing</p>
<p>Monitoring code rates look OK -> beam on target (attachment 10)</p>
<p>05:14</p>
<p>Beam intensity looks OK, Target density 3.11e11. Ring pressure YR09 2e-10 mbar.</p>
<p>All checks OK</p>
<p>Monitoring code rate looks OK -> beam on target</p>
<p>06:20</p>
<p>Beam intensity OK, Target density 3.1e11. Pressure YR09 1.9e-10 mbar.</p>
<p>FEE temps OK</p>
<p>System checks OK</p>
<p>Statistics and rates of all FEEs OK</p>
<p>Merger and Tape server OK</p>
<p>Monitoring code rates look OK -> beam on target</p>
<p>Merger statistics (attachment 11)</p>
<p>7:15</p>
<p>Beam intensity 2E7, target density getting bad 2eE11. WIll fix it from the lab.</p>
<p>FEE temps OK</p>
<p>System checks OK</p>
<p>Merger OK</p>
<p>Stats OK</p> |
