1. T1 hardware Detector Control System, OK several automates have been added, LV and HV sequences. FSM manages transition between Busy, ON and OFF states. Detector Safety System, OK Detector temperatures within expected range. Slow Control Loop, OK Main 40MHz LHC clock and Fast Command. DAQ system chain, OK added a firmware patch to the ORx mezzanine to increase the robustness of the system in the rare case the frame sent from the detector is corrupted. Trigger system, OK installed new fibers distribution patch panel. installed two new Trigger TOTFED boards with 3 ORxs each. deployed new Trigger TOTFED firmware FW OPTO Receiver FPGA, calculates the CSC hits multiplicity. FW Merger FPGA, calculates which sextant is fires based on majority voting (x out of 5 CSC planes) technique. Trigger chain under test, ready for next 90m  * run.
