CEB (BPC, IB, BS, NI, WI, PR, SR, SDB1) and MC SAT control systems have been recovered. BPC, IB and MC have been restored on the afternoon of last Friday to allow INJ subsystem recovery. The rest of CEB tower control systems have been restored today. Tomorrow we will proceed with the recovery of NE and WE SAT control systems.
Yesterday we recovered NE tower and the top stage of WE. Unfortunately Sc_WE crate was not able to transmit data to the DAQ. Investingating the issue we identify the problem: data transmission stopped as soon as the p6 DSP connected to the mirror (serial #44226) was inserted in the crate. This morning the board FPGA was reprogrammed and tested and the board has been re-inserted. WE control system seems now to be back to standard operational condition. The full suspension recovery should be now complete. We will have the final confirmation at next lock.
