  1. Collimation Working Group #127 Collimator Alignment Control IR 7 and 3 Patrick Bestmann 06/06/2011

  2. Overview

  3. Control of the Collimator alignment • The alignment of the collimators will be controlled using a dedicated survey train. • Strategy is the same as for the initial alignment (local smooting between quadrupoles) • Regular controlmeasurements • Control of the alignment after exchange of a collimator • The alignment deviations can be given to the collimator operation.

  5. Concept • Digital closerangephotogrammetry • Fast and non contactmeasurement of theactivatedcollimators • Wireoffsetmeasurementstodetecttrainpositionand link the different aquisitionvolumes. • Reliablereferenceoverlongdistances Collimators Quad Quad

  6. Survey train • The train is based on a combination of close range photogrammetry and streched wire measurements • All collimators in IR7 are equipped with additional photogrammetric targets (350) • 5 Overlapping wires are installed along the LSS7 as straight reference for the train

  7. Operation sequence • Installation in IR7 (uptream of MCBWV_4R7) • Startup and calibration check • Visual control of wires and weights • Start of Sequencer • Autonomous movements and aquisition • Online calculation and results in situ • Stability tests and aquisition ≈ 100 sec. • Operation Video

  8. Operation Video

  9. Benchmark Test • Real size mock-up in 927 • Two collimators and 5 reference magnets • Setup is measured with a Laser Tracker as reference coordinates for benchmark test • Fully independend measurements even with different targets. • Precision of reference measurements 0.15mm

  13. Test conclusion • System repeatability is below 0.1mm • Comparison to theory contains the uncertainty of the LTD measurements and the mechanical precision of the exchanged targets. • Precision is 0.2mm and already within specs but some optimisation margin can still be used

  14. TIM Security • Some security issues to adress • Some known issues from Tim 30*30 • TIM security rules with personell in place • Access restricted to team members • Airflow must be minimized (extraction point of sector 6-7 and 7-8) • Working on more advanced mobile control panel

  15. Status • Sensorsystems are running • All Subroutines are running • Calculation routines beeing finalized • Tunnelinstallation IR 7 completed • 5 overlapping wires • 10 pillars • 2x 111 m, 2x 85 m,1x 146 m • 350 Optical targets in place and measured • IR 3 in preparation

  16. To do list • Finalising Hardware configuration • Housing, wireing • Transfer from PC to PXI • More powerful and less consuming • Adding Mobile Control Panel • Tests for full system validation ongoing • Ready for winter stop 2011/2012 • Preparation for IR 3 Installation in long shutdown

  17. Planning • 09/11 Hardware finished Programm transferred to PXI • 10/11 Full validation in mock-up Including all possible configurations • 11/11 Documentation and Procedures (Installation, Calibration, Operation, RP, Safety) • 01/12 Installation and measurements in IR7 for 3 days (night shift) Manual measurements of LSS 7 Continious optimisation and developments with core team (C. Charrondiere, T. Feniet, P. Bestmann) and assignment of alternate specialists.
