  1. MACHINE DETECTOR INTERFACE WORKING GROUP STATUS Presented by Lau Gatignon PRESENT STATUS • An action plan was defined and agreed.Involves many other working groups! • A first design exists for QD0A short prototype is being prepared • A detector layout exists for CLIC-SiDA layout for CLIC-ILD is well under wayThis includes QD0 integrationAlmost weekly dedicated meetings • We are working with L* = 3.8 or 6 m • This is compatible with push-pull • A layout exists for the spent beam line, which is being refined. Background studies ongoing.An agreement has been found with EN/STI for the dump • The stage has now been set for dedicatedstabilisation studies for the final doublet • Work and discussions are ongoing concerningvacuum, backgrounds, IP feedback, vibrations,…

  2. MILESTONES AND DELIVERABLES FOR “2010” • Complete QD0 integration studies, also for CLIC-ILD. Include IP feedback, luminosityinstrumentation, stabilisation and prealignment equipment. Push-pull to be included. • Construction of short QD0 prototype, measurements on field quality, vibrations, mechanical stability, etcetera • QD0 stabilisation feasibility studies based on latest QD0 and detector design.Better understanding of interplay with various feedback and feed-forward systems.Hope to get more vibration and ground motion measurements (e.g. correlated) • Refine vacuum requirements and work towards technical solutions • Continued studies of backgrounds in collaboration with spent beam group (n, g), LCD, Collimation and other WG • Evaluate impact on MDI and spent beam of different crossing angle at 500 GeV • Start studies on radiation and shielding issues • Provide relevant input to CES working group • Try to collect information on cost wherever possible • Complete the MDI chapter for the CDR • Formalised collaboration with ILC-MDI/BDS Note: the items in red are the most urgent ones

  3. Have now to concentrate on the CDR! • Three volumes: 1. General introduction 2. Accelerator part (800 pages) 3. Detector part (150 pages) • Volume 2 to be ready in first draft for the October CLIC-ILC workshop in Geneva We will receive detailed chapter/section layout around Easter Writing in May / June / July • Volume 3 to be ready by March 2011 • Volume 2 will concentrate more on near-beam topics and post-collision lineVolume 3 will put more emphasis on backgrounds, physics, etceteraBut both volumes must be self-contained. • Next meeting on 23rd of April (normal style + discussion of Volume 2 layout)Dedicated meeting on 7th of May with presentations of status of the different topicsfor the CDR. A write-up for reference could be useful for a number of topics.
