  1. Developing Imaging Calorimeters for a SiD-Flavor Lepton Collider Jacob Smith Linear Collider Physics School Ambleside ,England 2009

  2. Resistive Plate Chamber Gas Electron Multiplier LCPS 2009, Jacob Smith

  3. ILC HCAL Requirements • Finely segmented readout on the order of 1 cm2 laterally and longitudinally  50 x 106 • Simple, cheap readout  front-end located on detector and highly multiplexing • Technology able to operate in high magnetic fields • Manageable (radius,cost) coil  thin active medium • Active element and electronics perform reliably over lifetime of experiment 10-20 yrs • Estimated 5000m2 active area  cost effective medium LCPS 2009, Jacob Smith

  7. RPC 1 m3 Test Beam z Incident Beam 24 40+ total layers 400 k channels Each 64 pads 1 m y x ~30 cm LCPS 2009, Jacob Smith

  8. Synergy of Analysis: 1m3 CALICE daq c++ c++ Quick event building Final event building CALICE binary binary data ASCII data binary data lcio lccd c++ marlin Event display Conditions data Fortran analysis C++ analysis Analysis ASCII data Test beam Run decision Test beam Run decision ‘Offline analysis’ ‘Online analysis’ Educational purposes only, Previouselypresentat at CALICE TB Metting June 09

  9. Future Plans • 1m3 and 3m3 simulations • GEANT4/Mokka(?) 1. Construction of 1m3 RPC • Write event builder, incorporate with CALICE sw • Cosmic Ray Test Stand (as layers/parts come) 2. Test Beam (shifts) 3. Data Analysis (offline analysis) • Write Papers (5+) • Calibration (muons, pions, multiplicity, efficiency), electron response, hadronic shower response (shower shape, response, longitudinal development) 5. Get PhD! LCPS 2009, Jacob Smith
