• Beam optics file, good starting point: H8A.10
• For beam optics scheme, please, refer to diagram posted on the wall of VELO control room (also available http://nahandbook.web.cern.ch/nahandbook/default/common/ZN2004.pdf )
• We are supposed to be at z= ~490 m
• Wire chambers MWPC03/04 are before us (404m)
• Wire chambers MWPC05/06 are right after us (509m)
• Scintillator Scint06 is the closest before us (should read about 1e6)
• Trim magnets can be used to lightly steer the beam: Horizontal => Trim7, Vertical => Trim8 (2mm per 50A up to maximum 250A)
• Bend magnets an be used to coarsely steer the beam H/V
• Beam de/focusing can be done with quadrupoles Quad14, Quad15, Quad16 (15 and 16 @ 0 blow up beam size)
• Make sure all collimators are widely open (unless you want muons or you actually want to collimate the beam...)
