Subject:
<p> OK - summary of events during this shift.</p> <p> </p> <p>1.TDCs. We have been sorting offline, and we have now established that between run 66 and run 79, the TDC mode was incorrectly set (not in common stop mode) after a DAQ crash causing broad loci in the E vs T spectra and times of the wrong sign. This was corrected from Run 81 onwards. </p> <p>2. The offline sort is behaving very badly and many of the sorts run since yesterday to now are wrong. Make sure you (a) sort on a different machine than the DAQ and (b) make sure that the sort is killed each time you start a new sort and (c) make sure that it is sorting the righrt run number.</p> <p>3. We have changed the trigger to a coincidence (S2-1 plus S2-2) OR S2-2 on its own OR PD.</p> <p>4. We have increased the beam rate to about 120 epA and we stay on this. Trigger rate should be about 7K with 4K live time.</p> <p>5. We will not change energy until early morning tomorrow, at the earliest. we will make a decision during the next two shifts based on what we see in the sort.</p> <p>Mike</p>
