<p><strong><span style="font-family: Helvetica; font-size: 12px;">Update on day and swing shift of December 13 and owl shift of December 14</span></strong><br style="font-family: Helvetica; font-size: 12px;"><br style="font-family: Helvetica; font-size: 12px;"><span style="font-family: Helvetica; font-size: 12px;"><strong>CEBAF status</strong>:</span><span style="font-family: Helvetica; font-size: 12px;"> </span></p><ul><li><span style="font-family: Helvetica; font-size: 12px;">Received 6.9 hours of beam during the day shift (https://logbooks.jlab.org/entry/3638519). 1.6 hours of beam time was lost to the ILMAD00 trips and the work on it. </span></li><li><span style="font-family: Helvetica; font-size: 12px;">Received 7.8 hours of beam during the swing shift (https://logbooks.jlab.org/entry/3638631). </span></li><li><span style="font-family: Helvetica; font-size: 12px;">Received 7.6 hours of beam during the owl shift (https://logbooks.jlab.org/entry/3638707).

The experiments aims for the first precision measurements of L/T separated kaon electroproduction cross sections above the resonance region. Details on the Kaon LT experiment can be found on: https://redmine.jlab.org/projects/kltexp/wiki</li><li>During the swing shift, we lost about one hour of beam time due to all HMS magnets and HB in SHMS interlocking (https://logbooks.jlab.org/entry/3638577). </li><li>On Monday, December 17, we will change during a control access the SHMS angle to angle of 6.00 degree. </li></ul></div><p><span style="font-family: Helvetica; font-size: 12px;"><strong>Data taking</st

The run conditions allows us to take data for beam currents of 13uA, 17uA, 21uA. &nbs
