Collimation Working Group #137
Collimator Alignment Controls
Patrick Bestmann 20/02/2012
Controls in March 2011
• Some collimators have been identified to need re-alignment.Showing an angular misalignment >1.9mrad • TCLA.A7R7.B1• TCTH.4L2.B1 • TCSG.A5L3.B2
• Reasons identified as:• conflict with adjacent vacuum chamber• Installation protection added on the support• IR extremities, dead end extrapolation
