<p><strong>Accelerator and experiment status</strong>:</p><ul><li>The accelerator is down due to CHL1 transformer issues. The estimates for the replacement of the CHL1 transformers, the restoration of CEBAF, and the continuation of the physics run have been changed in the last two days. </li><li>The new transformers have arrived on Saturday and need to be connected, installed, and enclosed. The first transformer will be switched on today and tested under load. The test of the new transformer should be finished by Thursday, March 15, and then the still running CHL1 transformer will be replaced. The goal is to complete the work on the transformers by Saturday, March 17, and to pump down CHL1 on Sunday, March 18. Wednesday, March 21, is the current estimate for beam restoration and Wednesday, March 28, is the current estimate for accelerator operation at full energy. </li><li>Before declaring physics run, the accelerator division would like to improve high-current running and beam optics. They plan to work with Hall A and C on beam tests, perhaps starting by Saturday, March 24. We will be able to take data during the beam tests but should not expect stable operation during that time. </li><li>Hall C is in restricted access. </li></ul><p><strong>Run coordination</strong>: Vladimir Berdnikov has taken over as run coordinator. I thank you all for your help and support in my first (rather uneventful) term as run coordinator. </p><p><strong>Shifts</strong>: Hall C shifts have been cancelled until (and including) the owl shift on Monday, March 19. The shift crews have been noticed and the shift schedule has been updated accordingly: </p><p><strong>Hall C Daily RC meeting</strong>: There will be no meeting today. The next meeting is planned for Friday.</p> </div>
