<p>Welcome to RC summary at September 18:</p><p>Unfortunately a lot of hours without beam in the last 24 hours. Beam was lost around noon yesterday due to a transformer failure in one of the RF cavaties. It took about 10h for repair and beam to come back.</p><p>We also had an issue with BMT occupancies in layer 4 Sector 1 before we lost beam but this problem has been fixed by Yuri and Rafo during the downtime.</p><p>We contiue with data production around 11:30pm. So far we collect about 360M triggered events with 1/2 plate OUT and negative target polarization.</p><p>Beam is currently down but should come back soon.</p><p>Plan for next 24H:</p><ul><li>increase statistics to about 400M events on this setting before changing 1/2 plate to IN</li><li>take production data with 1/2 IN and negative target polarization</li><li>keep an eye on HallC currents and check for bleedthrough</li></ul><p>We wil not have an RC meeting today.</p><p>Best,</p><p>Florian</p>
