<p>Sat 6/11 - Sun 6/12:<br />
* Beam tuning during Day shift, finally got reasonably good beam (see harp scans) and orbit locks.<br />
* Raster calibration during Swing: Not able to find calibration wires with beam. Instead use the edges where rates go up dramatically and assume they are at +/- 10 mm in x and y.<br />
* Took some rastered data with calibration target - see separate entries <a href="https://logbooks.jlab.org/entry/4001606">https://logbooks.jlab.org/entry/4001606</a>, <a href="https://logbooks.jlab.org/entry/4001616">https://logbooks.jlab.org/entry/4001616</a>.<br />
* Owl shift took data on empty (calibration) target without raster. First 15 nA with standard setup and DAQ (goal: find beam offset from CLAS12 nominal beamline using phi-dependence of z-vertex for exit and entrance foils), then 1 nA with zero torus and solenoid field for alignment.<br />
* Switched target to 12C for next 24 hours.</p>
<p>There WILL be a RC meeting today at 2:00 p.m. at the usual Zoom coordinates - see <a href="https://clasweb.jlab.org/wiki/index.php/RGC_RC">https://clasweb.jlab.org/wiki/index.php/RGC_RC</a> .</p>
