1 Installation Status Remaining Issues RIKEN/RBRC Itaru Nakagawa

2 North IR this week Restore OASys cameras after scaffold disassembly, night shot. 50 ohms registers installation of calibration pulse, N.St-3,Oct-6&7,Gap-2 ADTX communication check St.2

3 Repair work Calibration Pulse (N.St-3,Oct-6&7,Gap-2) Consistent with other gaps ~ 600 -> OK!

4 North Arm Concerns LocationProblemEffectSolution St3, Oct8, Gap2 Deformed calibration pulse Time smearing test Negligible effect on gain St3, Oct6&7, Gap2 Large calibration pulse Timing different, ADC saturation Add 50 ohm registers  St3, Oct4&5 Deformed calibration pulse Time smearing test Negligible effect on gain St-3, Oct-1Noise > 5ResolutionHigher HV?

5 South IR this week Completed South power/GTM infrastructures Cathode cables, ADTX-FEE install Noise & Performance tests (HV on/off) Noise hunting after decap. Work OASys illuminator repair Inconsistent cathode cabling btwn octants Improved ground connections (Jimmy) Station-1 Scaffold Disassembly (carpenters)

6 Inconsistent Cabling Updated DB for Octant-6, station-3 [11/30/08 17:06]. North arm –station 3, octnat5, half octant 0, cathodes 0 and 2, strip#226~240  Updated DB, OK –station 1,octant0, half octant 0, gap 2, cathodes 0 and 2.  To be confirmed soon. South arm –station 3, octant 2, half octant 1, gap 1, cathode 0 and cathode 2 (counting from 0); –station 1, octant 0, half octant 0, gap 0, cathodes 0 and 2.  Consistent with Actual Cabling. OK
