Communications | - POWER OUTAGE ON THE WHOLE CERN SITE SINCE 8AM - NO ESTIMATION ON POWER AND BEAM. After contacting the control room we decide to stop shifts until the power is back, and we meet at 8PM at T9 to check again with CR; if no changes happen we will meet again tomorrow at 8AM. |
Online&DAQ Report | - The external trigger signal delivered to the CU had a wrong TTL polarity, resulting in the CU being triggered on the falling edge of the trigger occuring 800ns later than the rising edge; this was corrected and the external trigger signal was aligned with trigger requests from TKR and CAL. New test of DAQ sync will have to be performed to verify if we can work at higher rate (200 evts/spill was the max stable rate tested so far) |

Communications | - Magnet failure: MNP17 colling system failure at 1AM stopped data taking for several hours but no damage on hardware. Physics restarted after 2 hours w/o silicon tagger for CAL calibrations. Magnet repaired in the morning | |
