UN 36_00060 = CMM Procurement Leitz Reference Model 45129 CMM manufactured by Brown & Sharpe in Wetzlar (Germany) is on order. It should be shipped after in-situ special tuning currently scheduled for the week of March 6 th. It is then expected to arrive at SLAC end of April. CMM weight capacity is 3000 kg. CMM measuring range is 0. 9 x 1. 5 x 4. 5 meters. CMM resolution is 0. 1 microns or 0. 000004 inches. CMM spatial accuracy is a formula based on the length L (in mm): Original: 2. 0 microns + L/350 Special calibration for undulator segment: 1. 5 microns + L/500.

Tunnel Alignment Sequence: Establish survey network in empty UH. Mark bolt-hole floor positions for pedestals. Align pedestals. Survey girder components. Final alignment & integration of monitoring systems. Items to work on: Finalize penetrations & other access. Analyze mechanical requirements for cam movers. Make a local controller for cam movers. Allow schedule for repeated surveys due to tunnel movements. February 8, 2006 Undulator Alignment Plan 8 C. Le. Cocq lecocq@slac. stanford. edu
