Chance this happens as early as Friday 2/20 for Arc7. Better chance Arc7 slips to following week. RSEP8A could happen any evening this week, although we'd likely need to lock-up the BSY in addition to the NL and SL. Key here is it is unlikely there will be a day shift this week or next where we can do this, but plenty of afternoon / swing shifts beginning around 3pm that could be targeted.

Do you want to target a specific day this week for RSEP8A, or wait until Arc7 can also be done on the same afternoon?

Once the PTW is on-issue, this task is approved.

Rather, rad surveys of the NL and SL will occur beginning at 730am tomorrow (Tues 2/17) morning, followed by Restricted Access in each linac.
