[Rgc] [EXTERNAL] Target Change Tomorrow (Sunday)?

[Sebastian Kuhn]

Hi Zulkaida,

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.

More tomorrow - Sebastian

Dear All,

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.


Best Regards,

Zulkaida Akbar
