  1. Collimation Working Group #137 Collimator Alignment Controls Patrick Bestmann 20/02/2012

  2. 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

  3. Results All 3 collimators showed a rotation around the Z axis dx E S dy

  4. Controls in January 2012 List of collimators to be controlled Beam 1 ---------- TCLA.B5R3.B1 TCSG.B5R3.B1 TCSG.A5R3.B1 TCSG.4R3.B1 TCTH.4L2.B1 changed due to X2ZDC Modifications TCTH.4L8.B1 TCSG.D4L7.B1 Beam 2 ---------- TCSG.A6R7.B2
