[Rgc] [EXTERNAL] Re: Anneal tomorrow, not today?

[Christopher Keith]

I got the impression at yesterday’s meeting, you preferred to wait until the weekend.  Brock and Maxwell are willing to come in Saturday afternoon.  We can always continue beam on negative polarization until you have the statistics you want before swapping to the next target, say on Tuesday instead of Monday.

However, we really need more data for the opposite target polarization. Is there a reason why the target group would prefer to delay the anneal/polarization reversal to tomorrow? Otherwise, I would tend to stick with the plan of switching today. (After all, we don’t know how bad things might be over the weekend… :-(
