From beam overlap tests ~ 75% of the beam is destroyed in this time.</p> <p>Beam halo appears slightly reduced. This may be due to reduced intensity and reduced injection rate (20 s vs 5s previously)</p> <p> </p> <p><strong>18:00</strong></p> <pre> FEE64 temperatures OK ADC data item stats OK per FEE64 Rate spectra OK Beam intensity 1.17e+7 particles Target density ~5.25E11 atoms/cm2</pre> <p> </p> <p><strong>20:28</strong></p> <pre> FEE64 temperatures OK ADC data item stats OK per FEE64 Rate spectra OK Beam intensity 1.08e+7 particles Target density ~3.84E11 atoms/cm2</pre> <p> </p> <p><strong>23:58</strong></p> <p>Temps OK.

Write to disk OK.</p> <p>Waveforms attached.</p> <p>Beam keeps going away due to "solenoid" issues.</p> <p>On-line analysis screenshots attached.</p> <p>Without beam, we see a clear noise spike in all detectors every 50-200 seconds randomly. This is *not* correlated with beam injection or dump.</p> <p>Checkloaded - no effect. Beam back - no changes.</p>
