Woodley, ILC@SLAC Beam Delivery Group3 bending in energy collimation system reduced for zero net coll/FF bend; reduces max η (was 0.213 m) Andrei’s “ff126” modifications applied to latest NLC coll/FF system Includes: spoilers absorbers muon shields photon masks PCs stoppers instrumentation feedback

5. December 15, 2004M. Woodley, ILC@SLAC Beam Delivery Group5 Plans add energy spectrometers (~55 m) add polarimeters (~50 m) “Push-Pull” or longitudinal IR separation? 2 mrad coll/FF/extraction design incorporate Brett Parker’s design for fast extraction / tune-up into NLC dump line adjustments for PPS (people in one IR with beam in the other IR)
