SEI CPS Timing Distribution System - BSC1, BSC2, and BSC3 
Implemented the new timing distribution system for the CPS's units (BSC's only) in the LVEA. Changes include using BSC2 CPS_1 unit as master. The timing signal is feed to a STS-2 Distribution chassis and distributed to all other CPS units. The STS-2 Distribution Chassis was placed in SUS-R6 floor rack.

Attached is a spectra of ITMX ST2 GS13 took after the timing system was changed (in blue), and compared with the reference from Seb's alog 9537 from last week (in yellow). Clearly, the combs do not appear any more.
