CALICE overview

CALICE overview

• International RD 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.

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.

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.

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.

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 RD would need to continue. MAPS could
  reduce cost of ECAL significantly.
