Considerable cause of additional bad chips of those ladders will be unstable FEM or optical fiber connection at SPIRO side.

Run-12 13.5 weeks of physics running
4 weeks of p+p 200GeV (mid of Feb ~ mid of Mar) 5 weeks of p+p 500GeV (mid of Mar ~ end of Apr) 2 ¼ week of Cu+ Au 200 GeV (under assumption) 2 ¼ week of U+U 193 GeV (under assumption) Our goal for 4-week 200GeV pp run |z| < 30cm : 10.5 pb-1 |z| < 10cm: pb-1 We got 88% We got 76%

LV current for all pixel ladders are always normal during run.
Data taking with PHENIX-DAQ and OPS software Occasionally, failed to get hit data from B0-L5-N, B0-L9 and sensor 2 of B1-L11-N. Few noise pixels could be seen. Test (with DAQ in standalone mode and OPS) had been done during APEX on Mar 7th. B0-L5-N B0-L9-N B0-L9-S B1-L11-N Sensor 3 Sensor 2 Sensor 1 Sensor 0 with DAQ big partition (Mar7th) X with DAQ standalone (Mar 7th) O with OPS Optical Intensity of Data Line (Mar 7th) (dBm) -12.28 -10.92 -10.58 -12.37 -12.47 -10.50 -13.37 LV current (A) 3.39 A 3.99A 3.83A 3.48A Final physics run on Mar 7th LV current for all pixel ladders are always normal during run. It means broken of bonding wire should not be happened and sending DAC values had been done successfully.

Physics Run on Mar 8th Plan
B0-L5-N B0-L9-N B0-L9-S B1-L11-N Sensor 3 Sensor 2 Sensor 1 Sensor 0 with DAQ big partition (Mar8th) O LV current (A) 3.42 A 4.01A 3.85A 3.50A First physics run on Mar 8th Hit data was back again. The reasons that bad ladders were recovered are unclear. Plan Replace FEM boards to which bad ladders connected with spare FEM boards. Check optical modules (blow with air blower) at access day (next Wed).
