[Hallb] Possible early start-up of Hall B for RG-L

[Daniel Carman]

Folks,

At this morning’s MCC meeting it was announced that the progress on preparing the machine to start beam delivery
for physics is advancing and beam delivery will start soon. However, there are a number of issues that may prevent
delivery of beam to Hall D until early next week. If that is the case, there is a chance beam delivery to Hall B at
1-pass could begin on Saturday morning (Mar. 29).

We need folks to be available to take shifts if MCC plans to delivery beam to us. We will (perhaps) learn more at
today’s 1:30 p.m. MCC scheduling meeting. Until then I want to get standby shifts set up for Mar. 29 (day, swing),
Mar. 30 (owl, day, swing), and Mar. 31 (owl) - shift experts + shift workers.

Obviously the initial focus will be on beam tuning to the Tagger and then to the Faraday cup. This will likely be
an extended process so we will need our beamline experts available whenever beam delivery commences.

I will send out email later in the day with an update on the plans from MCC for beam delivery. So please let me
know your availability to serve from Saturday day through Monday owl if necessary.

Regards,
Daniel
RG-L PDL
