<p>A target change on Monday during the day shift will be fine.</p>
<p><br>
</p>
<p>I'll assume it will be either NH3 or ND3, depending on the
relative amount of data on the two. The RC should announce this
at the morning meeting and let RadCon know that we'll need their
support. Request a Controlled Access if there are others that
want to perform work in the hall. Will there be an accelerator
maintenance day later this week?</p>

You are right, the first 4 hours were wonderful (Run 17118
collected 100 M events in less than 4 hours) but now the beam
has been off since 9.15. So, we will run CH2 IN until tomorrow
around noon and then flip to OUT and run OUT configuration until
Monday morning. And yes, let's discuss about what target to
switch to on Monday and whether we should flip the solenoid
polarity. </div>

<div class=""><br class="">
</div>
<div class="">as far as I can tell, over the last 6 hours (since
beam finally came back) we have taken 120 M events
corresponding to 0.09 mC integrated charge. To get the desired
quota on CH2, we would need nearly 8x as much - so it looks to
me like tomorrow will be too early to switch targets. I would
propose we keep running with CH2 until Monday morning.
Meanwhile, we can use this thread to discuss what we should
do on Monday - what target to switch to, and whether to flip
the solenoid polarity.</div>

I am sorry to make a new email thread. But there is
good news. We got the beam, and it has been stable. In
4 hours, we collected ~100 M events (Run 17118). If
the beam keeps stable, We will have ~ 400 M events
(200 M HWP In + 200 M HWP Out) by tomorrow morning.
So, should we change the target tomorrow during the
day shift? What kind of target? Let's have a
discussion and decision here.</div>
