5. Problems Masked SDC wire IH was not fixed to SDC (upside) ASD card changed : 30 -> 109 Didn’t use “clean ground” OHVR7U, R8U, L12U was fixed with optical cement IHL2,R2 booster didn’t work Input line of TUL : 32ch cable -> 64ch cable (extra 32ch was dummy) Network sometime broke (caused Target control system trouble) PM AMP caused noise (IH trigger and TDC line) -> Changed channel BPM : Veto counter was broken, a trigger counter was moved Trouble on Radcon (“Delayed signal” used ?)
