=== Weekend ===

==== Report of work ====

 * Pump down for central area was postponed for 2 weeks.
 * Type B: BS still has some trouble, it was decided to open chamber again.
 * Type Bp: OSEMs were fixed, and it looks OK. Beam position on QPD was off. PRM needs more tuning and measurement. It will be done in the next week.
 * Y end temperature became low by 3 degree.
 * IOO: Found touching AOM driver and fork, and it was making a big group loop. Once it was released the noise became much smaller.



==== Work plan ====
 * Yend pump down start today.
