<br>
If possible, I would like to have a short alignment run with<br>
the torus turned off, but with the solenoid on.<br>
<br>
This would reduce our background from very low momentum electrons<br>
and should be complementary to the data we have already<br>
acquired (run 2467). In that data, we can use the target position<br>
as a constraint, but as I said we have a large contamination of<br>
very low-momentum tracks.<br>
<br>
An hour should give us good statistics.<br>
Because of a doctor's appointment, I may not be able to be<br>
at today's meeting, but please discuss this.<br>
<br>
regards, Mac<br>

Dear All,<br>
<br>
Steve (PD) gave us an update this morning at the MCC meeting. If you read somewhere in the logbook that the beam might be back in four hours around noon — it won’t happen. The best case scenario would be sometime during the swing shift when we could expect beam to back. The network issue is nearly resolved. However, there are a lot of remaining items the accelerator team needs to address before they can deliver beam.<br>
<br>
This gives us an opportunity for Hall Access if anyone needs it. Please let PDL and me know if you do need it.<br>
<br>
Additionally, if anyone needs special runs that do not need beam, such as cosmic runs, LED runs, calibration runs, please let me and the shift leader know.<br>
<br>
Realistically, we have about two days of data taking left if all goes well. Therefore, we must have a meeting today at 3pm to discuss the remaining plans.<br>
<br>
Let’s meet at 3pm in the counting house then. Meeting link is below<br>
