Yuris ILC 20 mrad dump lines
IR1 20 mrad
Andreis 20 mrad ILC FF (x 4)
NLC BSY dump lines

Andreis ff126 modifications applied to latest
NLC coll/FF system
bending in energy collimation system reduced for
zero net coll/FF bend reduces max ? (was 0.213 m)

• Includes
• spoilers
• absorbers
• muon shields
• photon masks
• PCs
• stoppers
• instrumentation
• feedback

Plans

• add energy spectrometers (55 m)
• add polarimeters (50 m)
• Push-Pull or longitudinal IR separation?
• 2 mrad coll/FF/extraction design
• incorporate Brett Parkers design for fast
  extraction / tune-up into NLC dump line
• adjustments for PPS (people in one IR with beam
  in the other IR)
