1. ,C. Kiesling, 10th BPAC Meeting, KEK, Japan, Feb. 7-9, 2016 1 VXD Commissioning Organizational Matters (in response to the BPAC October report) Overall PXD/SVD coordination strengthened:  2 nd DESY Test (PXD / SVD common beam test) bi-weekly (Seevogh) meetings between PXD and SVD established common subsystems: CO2 (MARCO) + Slow Control + Interlock DAQ crew (KEK) integral part of project  BEAST 2 project VXD-Commissioning leaders nominated: C. Marinas & K. Nakamura (deputy) Commissioning crew established (already active in the DESY Test) PXD / SVD ladders as in DESY test CO2 (IBBelle) and installation as in phase 3

2. ,C. Kiesling, 10th BPAC Meeting, KEK, Japan, Feb. 7-9, 2016 2 Major Steps during Installation & Commissioning: 1.Preparation of the Beam Pipe[beam pipe “ready”] 2.PXD halves on Beam Pipe (+ electrical test ) 3.SVD halves on Heavy Metal (+ electrical test) 4.Common electrical test, CO2 cooling[VXD “assembled”] 5.Common Cosmic Ray Test 6.Installation of Cables from the Docks to the outside 7.Installation of the VXD into Belle[VXD “in place”] 8.Connection of all cables and services to the docks 9.Close warm dry volume / flush with N2 10.Turn on CO2 Cooling 11.Turn on power 12.Cosmic Ray Test[VXD “ready”] Milestones for the VXD Commissioning detailed list of steps in the backup
