<p>07:20</p> <p>Started a background run while the cave is open.</p> <p>All ASIC settings remain unchanged, we just have no beam.</p> <p>We see obvious difference in the rate plots for DSSD2 from the monitoring code. Attachment 1 - beam on, Attachment 2- beam off.</p> <p>Data rate ~1.6 MB.sec</p> <p>Checks OK.</p> <p>10:30</p> <p>Lost DSSD4 again. Writing a lot of junk to disk.</p> <p>Switched to MEC channels. Still writing lots of data. Stopped the run.</p> <p>Required ASIC check load on aida13,14,15,16 in order to bring rates back down.</p> <p>Slowly re-biasing detector. At 35V</p> <p>Moved detectors fully out for safety. Left potentiometer = 18.86 mm and right potentiometer = 19.8 mm. No effect on leakage currents.</p> <p>Past 40V we large increases in leakage current. Only went up to 10uA and didn't trip. Set to 40V, current back down to normal levels.</p> <p> </p> <p>Note we have turned the target compressor off to heat up before cooling later to try and get higher densities. This follows a drop in E1 yesterday reducing the target density.</p> <p>10:45</p> <p>Started new background run - Run 69.</p> <p>DSSD4 set to MEC.</p> <p>Thresholds still as in previous runs (120, 80, 80 keV).</p>
