<p>RC summary September 20:</p><p>Doing Day shift we did some raster adjustment (https://logbooks.jlab.org/entry/4044155) but then lost beam around 3:30pm due to an RF issue at the accelerator. It took the whole swing shift for repair and we got production beam back around 2am.</p><p>We collected another 50M on NH3 with negative target polarization and 1/2 plate IN. Overall statistics for IN and negative taget polarization is about 450M triggered events.</p><p>We switched 1/2 plate to OUT and collected another 13M before beam was cut for maintenance. Overall statistics with OUT and negative taget polarization is about 420M triggered events. </p><p>Today is RF recovery during day shift and we expect beam back for swing</p><p>Plans:</p><ul><li>hall will be in restricted access</li><li>target change to ND3</li><li>detector maintenance (FTOF PMT, DCRB timing)</li><li>walkthrough</li><li>when beam back: harp scan to tagger dump, moller run, continue production (we might need!
  to adjust raster back to the values for ND3)</li></ul><p>We have an RC meeting today at 2pm (https://jlab-org.zoomgov.com/j/1608674253?pwd=SFZyYmZLWXJieGtpV2dEdVRiUEJnUT09&from=addon)</p><p>Best,</p><p>Florian</p><p> </p>
