[BTeam] Proposed Fall Schedule in light of CC1 issue

[Arne Freyberger]

Colleagues,
In discussion with Cryo the following adjustments to the Fall schedule 
are proposed.   The highlights are:

 1. CC1 repair complete and South linac at 2K by Fri. Nov. 6th
     1. This assumes an easy fix.
 2. CEBAF 12GeV Spin-up
     1. Start date remains Nov. 9th
     2. Beam operations will have a short break while the South linac RF
        system is optimized.
     3. CEBAF Plan still maintains almost a week of contingency (147h)
 3. CEBAF Beam operations over Thanksgiving.
     1. CEBAF will be placed in Hot Stand By mode Wednesday evening to
        Friday morning
     2. Beam Operations resume Black Friday and continue through to Dec.
        21st
         1. Original plan had beam off Wed morning and resuming the
            evening of Tues Dec 01
 4. LERF Restart will take place during the break in CEBAF Operations
    for South linac RF optimization
     1. LERF restart is from  Nov 14th to Nov 22
     2. LERF Restart plan has been stripped of contingency
     3. Opportunistic LERF operations prior to Nov. 14th are being explored.

The image below is a whiteboard interpretation of the new schedule.   
The schedule can also be viewed at:

This is a fresh plan, comments and discussion are welcome.   Email 
updates will be made when significant changes and upon the arrival of 
new information.  Please forward to anyone who would benefit from this 
information.
