Data from B0-L5-N, B0-L9 and chip8-11 of B1-L11-N are unstable.
Considerable cause of additional bad chips of those ladders will be
unstable FEM or
optical fiber connection at SPIRO side.

3. 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%

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.

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.

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).
