<p>All system checks OK</p>
<p>Target density 3.4e11</p>
<p><strong>11:50</strong></p>
<p>System checks OK.</p>
<p>No beam in the ring yet. Althoug some injection may be taking place at low intensities</p>
<p>Target density appears much more stable than before.</p>
<p>Density currently just above 1e11 at/cm2</p>
<p>Note maintanace is required to appc025 so anydesk is currently down.</p>

<p>Merger OK, Tape server OK</p>
<p>ADC data item statistics looks as before. OK</p>
<p>FEE temperatures look OK</p>
<p>System checks OK</p>
<p>Leakage current stable</p>
<p>Attachments 1-5 (also waveforms)</p>

<p>Merger OK, Tape server OK</p>
<p>ADC data item statistics DO NOT looks as before. NOT OK</p>

<p>Notice the statistics for aida01-aida04 (DDSD 0, top left) were counting extremely high in the previous check (attachment 6). Previous rate was 0-1 counts.</p>
<p>We tried ASIC check load three times but not effect on the rate.</p>
<p>We then tried 'shaking the detectors' by moving the left pneumatic in and out again.</p>
<p>Rates go back to normal levels (0-1 counts)</p>
