4New Institutes are Welcome ! Recent DevelopmentsCASTOR approved by CMS-MB as CMS baseline detector onOne calorimeter will be built by end of (224 channels)FEA calculations completedPrototype construction & assembly study completedSkeleton construction studies completedFull length octant prototype constructed and beam-tested in August, 2007EDR to be completed by end of October 2007CASTOR sim-digi software in HCAL CMSSW-1_7 release10. Resources approaching required level for completion. Missing ~ 150 k€New Institutes are Welcome !Currently working on:- test beam data analysis,- electronics, construction- software ( implementation in simulation of digi & reco…)- physics simulations, …..

19Summary New Institutes are welcome ! Forward Physics spans a broad range of pp and HI high energy physics topics, from fundamental properties of QCD to new physics phenomena.Large cross sections ensure early publications on various topics.Discovery potential:- Beyond Standard Model (BSM): Large amount of missing transverse energy (MET)- Higgs: Vector-Boson-Fusion (VBF): Two jets at forward/backward rapidities (pp→jj H X). Lower background than the dominant gluon-gluon fusion channel (see David’s talk).- Exotics in HI Interactions: “Strangelets”, Disoriented-Chiral-Condensates (DCC)CASTOR calorimeter project is progressing fast:- Lots of data taken in test beam; Analysis under way.Engineering design review scheduled for the 31st October. Document in final stage.Construction of calorimeter to start in November 2007.Aim & need to be in beam line as soon as LHC starts, to take advantage of low lumi runs. New Institutes are welcome !
