[Sbs] Beam schedule update

[Mark Jones]

 Hello all,
      I got news from Doug and accelerator at the 1:30 meeting about the start up date for  beam.
The start of the accelerator 2K cooldown is unclear, since it is taking longer than originally
expected to get the cryo OSP’s reviewed.
 At this time, it is unclear when the 2K cool down will start as it requires
a number of approvals and complex/risky tasks are being reviewed very carefully.
Maybe in 2 weeks. And once 2K cool down starts, it is two more weeks before the machine
gets to 2K and then approximately one month to get beam to physics.
Thus, we are now looking at something close to a two-month delay
which puts beam start for all halls some time in Sept.

So we will keep an eye on these 2K milestones.

In terms of shift schedule, once the 2K is achieved and we are about one month
out we will have a better idea of the beam start date.


The schedule will be shifted to accommodate for this shift in the beginning
so beam will run to sometime in May 2024.


Cheers,
           Mark
