<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
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
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
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
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)
