  1. INFN Perugia INFN Firenze CERN M.Lenti • Separate pionsfrommuons <1% levelbetween 15 and 35 GeV/c • Tracktime at 100 ps level • Partecipate in the L0 trigger Mirrors RICH 17 m Beam Pipe • Neon asCherenkovradiator • mosaicofmirrors (17 m focallength) • twospotswith PM (1000 PM per spot) • beam pipe passingthrough PM lodging disk

  3. Milestones: • Design formirrorsupport: 30.06.2011 • Vessel installationready: 30.04.2012 • Mirror and PM installation complete: 2.12.2012

  4. Vessel (CERN): vacuumproof ! Gas system simplified: makevacuum, theninject pure Neon M.Lenti

  5. Vessel tender notsubmittedyet (CERN responsibility) M.Lenti

  6. Photomultipliers • 1944 PM available (quality test ongoing) • 2000 HV divider in preparation (custom made) PM mechanics in fabrication FE electronics in preparation M.Lenti

  13. Mirrors • Allmirrorsready (18 hex + 2 semi-hex), now at CERN • Quality test made in Italy in may 2011 • Coatingtobedone at CERN • Mirrorsupport system with a “dummy” mirror: • hung at the center • alignedwithmicrometricpiezo.motors V.Carassitiwillengeneerize the mirrorsupport system In the fall 2011 M.Lenti

  19. MirrorSupportPanel Goal: engeneer project by the end of 2011, then go for tender (INFN responsibility) M.Lenti

  20. Milestones RICH 2012 • Installazione dei PM e dell'elettronica di FE 31.08.2012 • Installazione degli specchi 31.08.2012 M.Lenti

  21. RICH Schedule V8.4 (baseline) Assumes Rich vessel in time for TR today Very short time window To get ready for the TR Temp. installation… M.Lenti

  22. RICH Schedule V8.42 (back-up) Non-conform with baseline planning today TR Outside beam periods M.Lenti In this scenario the RICH could only be used if there is a window to prolong the TR in 2013 !

  23. Conclusions • Lotof progress on manyitemsof RICH • Vessel production (CERN responsibility) delayed • Mirrorsupport system tobefinalized • The RICH is on the criticalpathforseptember 2012 technicalrun M.Lenti
