1 Collaboration K. Artoos, CTC 8th February 2011 Active Structures Laboratory Department of Mechanical Engineering and Robotics Université Libre de Bruxelles (ULB), Belgium Institut de Recherche sur les lois Fondamentales de l'Univers CEA (Commissariat à l'énergy atomique) Saclay, France Laboratories in Annecy (France) working on VIbration STAbilisation 1 Contact: Chr. Collette Promoter ASL: A. Preumont Contact: F. Ardellier Desages, M. Fontaine Contact: A. Jeremie Status: No collaboration signed yet with CERN Unilaterally funded by Brussels Capital Region Project Chr. Collette Unpaid associate Status: Contribution exceptionelle de la France au CERN (EDMS ) WP (in CTF 3 collaboration, no addendum for stabilisation) Status: EUCARD 2013 Contribution exceptionelle de la France au CERN (EDMS ) WP (in CTF 3 collaboration, no addendum for stabilisation)

2 Deliverables Studies of measurement methods independent from the feedback loops, in particular optical ones and application to the mock-up. ACCORD TECHNIQUE D’EXECUTION NO.4: du protocole de collaboration k1597/dg K. Artoos, CTC 8th February 2011 Status: SIOS tri axis interferometer purchased Tests ongoing on mock up (RFQ) for pole tip vibration measurements Tests at CERN foreseen in February on membrane and quadriped

3 Deliverables 3 K. Artoos, CTC 8th February 2011 EUCARD WP 9.3 LINAC & FF Stabilisation Sub task 1: CLIC quadrupole module Sub task 2: Final Focus Test stand 4/2009Milestone 1 : Calculs vibratoires de l’aimant du démonstrateur (rapport) 12/2009Milestone 2: Construction et qualification d’un démonstrateur simplifié (version LAPP) et du(es) prototype(s) de contrôle servant a ce démonstrateur (rapport) 3/2010Milestone 3 : Analyses vibratoires de l’ensemble du démonstrateur (rapport) 6/2010Milestone 4 : Développement de la méthodologie de contrôle et application au démonstrateur (plusieurs combinaisons) 10/2010Milestone 5 : Rebouclage des calculs vibratoires avec les mesures sur le démonstrateur (rapport) 3/2011Milestone 6 : Evaluation des performances (Rapport) 9.3.1Characterisation of noise/vibrations sources in an accelerator 9.3.5Commisioning of CLIC quadrupole module 9.3.6Quadrupole mock-up manufactured and ready for installation ACCORD TECHNIQUE D’EXECUTION NO.4: du protocole de collaboration k1597/dg

4 4 K. Artoos, CTC 8th February 2011 Development of stabilisation support FE model of MBQ type 4 Modal analysis Will participate with modal and water cooling vibration measurements in ISR Characterisation in accelerator environment Development seismometers, characterise Eentec chemical seismometer FF stabilisation

5 5 K. Artoos, CTC 8th February 2011 Objectives ASL Development of a control strategy for the stabilisation of a single module, with equipment compatible with the accelerator environment. Develop a scaled prototype of the model. Integration of the control strategy of a single module in a global strategy for a multi segmented system. Investigate alternative sensors to measure low frequency, small amplitude vibrations
