<p>Dear All, <br>
<br>
we are still in production mode at 35 nA. Beam has been down most
of the owl shift, due to shunt module MXU6S03 and MXV4R04
replacement. The beam has not been reproducible afterwards (see <a
class="moz-txt-link-freetext"
href="https://logbooks.jlab.org/entry/3633996">https://logbooks.jlab.org/entry/3633996</a>).
At 5 am the crew chef requested the injection of tuned beam.
Tagger has been energized and all detectors have been turned off.
Beam was back by 7 am and it took another hour to restore beam
quality. Data taking has proceeded regularly afterwards, except
for another 1 hr beam down for some <a
href="https://logbooks.jlab.org/entry/3634065"> problems with
MXF4R01 mismatched </a> resulted in <a
href="https://logbooks.jlab.org/entry/3634057"> trim card
MQA4A10</a> being replaced.<br>
We have collected slightly less than 1 billions events in the last
day for a total of 2.5 billions RGK production events. <br>
<br>
The plan is to continue until Monday morning when beam will be
terminated for beam studies. <br>
<br>
All the best, <br>
Annalisa (RC) </p>
