<pre wrap="">The beam will be down tomorrow and Hall B will be open. The accelerator plan is to
change the energy per pass to 1.1 GeV and change Hall B from 3-pass to 5-pass
beam. Hall B will be installing the HPS beam test together with the clas12 silicon
strips.
The beam will go down at 6:30 am and going to restricted access by about 7 am.
They anticipate being open till late in the evening and lock up before midnight.
Hall D major tasks for tomorrow are
1. Remove the downstream readout board first thing in the morning. During the day,
replace the electronic board with the extra "optimized" board in F117. At the same
time check on the attachment of the cooling tube to the cooling plate and repair. After
complete testing of the readout assembly, return to Hall B and reinstall on the mini-
Bcal.
2. Place radiation badges on/near the mini-Bcal to monitor radiation dose. Take
photos of monitors on location for reference.</pre>
