Presentation Transcript

  1. CALICE overview • International R&D project on calorimetry for the ILC investigating a number of technologies. • European and national funding with 41 institutes and over 200 members. • ECAL: tungsten with readout via scintillator tiles, diode pads, MAPS • HCAL: steel with analogue readout via scintillator tiles (AHCAL), and digital readout via RPCs or GEMs. • Tail-catcher: iron with scintillator strips.

  2. CALICE-UK • Birmingham, Cambridge, Imperial, Manchester, RAL, Royal Holloway, UCL. • Second round of STFC funding Apr 2006 – Mar 2009 of about £3.0M (5RAs, equipment, travel etc.). • Five workpackages • WP1 test beam studies of prototypes • WP2 DAQ • WP3 monolithic active pixel sensors • WP4 mechanical and thermal studies • WP5 physics and simulation studies • Post Mar 2009 there is likely to be continuing interest in all these areas, requiring further funding.

  3. Towards detector EDRs • UK is leading DAQ development; we aim to provide DAQ for next calorimeter prototypes leading up to EDRs. • Work is becoming more generic, possibly with detector-wide application; LCFI? • Combined test beam running with vertex detector, tracker and calorimeters? • Funding continues via EUDET until Dec 2009 to demonstrate readout of a slice of ECAL. EUDET planning a new application for further four years of funding; DAQ could be part of this.

  4. Towards detector EDRs • Physics studies and detector optimization will continue beyond Mar 2009. • Key issue is jet energy resolution, dominated by “confusion” term, particle flow algorithm approach is essential; UK leading area and an emphasis in our physics studies. • b-jet identification essential in many channels and now being applied in CALICE WP5; requires close collaboration.

  5. Towards detector EDRs • Mechanical studies need to move on towards whole detector issues; clear area for collaboration. • If MAPS is demonstrated as a viable option by Mar 2009 R&D would need to continue. MAPS could reduce cost of ECAL significantly.
