  1. Detector Development for Terascale Physics:Working group summarySee agenda + slides at:https://indico.triumf.ca/conferenceDisplay.py?confId=618+ 1 August plenary talks from Lyn Evans and Chris Adolphsen Opportunities for Innovation and Research TRIUMF Town Meeting 1-3 August 2007

  3. The Higgs: can’t live without it • A Higgs (or Higgs-like) particle is required in the SM • Not just a mathematical trick, but effects measurable processes • Eg: Contribution which grows like me2s cancels between Higgs diagram and others e+e- W+W- McPherson --Terascale Detector Development TRIUMF Town Meeting LEP EWWG, hep-ex/0312023

  4. Constraints on Higgs boson H0SM • MH (summer 2006) • c2 minimum: • 85 GeV • Direct Search LEP: • > 114 GeV @ 95% C.L. • Precision EW + LEP direct search limit • < 199 GeV @ 95% C.L. EW Fits: MH free Param. Data from LEP, SLD, Tevatron • Complete the SM: • FindH0SM? • Beyond the SM @ 1TeV • New symmetries, compositeness , ... • Strongly motivated to avoid MH fine-tuning McPherson --Terascale Detector Development TRIUMF Town Meeting

  5. Next projects • Requirements for light Higgs-like scalar very strong • Can only be discovered and studied with direct production • Indications for ~ TeV scale new physics compelling, but nature of new physics unknown • There is no substitute for pushing direct energy reach into the TeV regime • Can see this clearly by general constraints on new physics models which are dominated by high-energy collider results • Many more physics areas as well • Top Mass/BR, W/Z physics, Gauge couplings, QCD, heavy flavour physics, meson spectroscopy / exotics, tau physics, … • Two colliders of relevance to next TRIUMF 5YP • LHC: Large Hadron (p-p) Collider at CERN • ATLAS detector: major ongoing Canadian efforts • Major upgrades needed after ~ 3 years of full rate data-taking • ILC: International Linear (e+e-) Collider McPherson --Terascale Detector Development TRIUMF Town Meeting

  6. Terascale Detector WG • Discussed overall SLHC (ATLAS upgrade) and ILC detector plans • Overviews by Dean Karlen and Nigel Hessey (ATLAS upgrade coordinator) • Emphasis on Canadian (potential) contributions • Reviewed detector mechanical design needs, assessed commonalities • Reviewed detector electronics design needs, assessed commonalities • Did not discuss, eg, renewal of electronics group basic infrastructure, computing hardware renewal, accelerator contributions in detail • But this is still essential to our program and needs 5YP inclusion! McPherson --Terascale Detector Development TRIUMF Town Meeting

  7. Cdn ATLAS Upgrade Projects • Forward Calorimetry at high rates • Significant potential problems with (largely Cdn built) ATLAS calorimeters at SLHC • Boiling liquid argon? Ion mobility at high rates? … • Possible solution: • New high rate calorimeter “shielding” LAr FCAL • Hadronic Endcap (HEC) electronics • Cdn-built detector may have pre-amp radiation failure • R&D on new technologies now, ready for replacement • Tracking • Complete ATLAS tracker replacement needed after ~ 3 years of high rate data taking • Strong Canadian leadership in diamond pixel detectors • Strong Canadian interest in tracking front-end readout McPherson --Terascale Detector Development TRIUMF Town Meeting

  8. Cdn ILC Detector Projects • Time Projection Chamber • Strong Cdn leadership for ILC TPC, synergies with T2K • Endplate sections with readout (GEM/MicroMegas) • Calibration system, gas system • Overall system integration engineering • Readout electronics • DAQ • Hadronic calorimetry • Fine grain Scintillator + SiPM readout • Allows particle ID, matching to tracking detectors with overlap suppression • Best resolution from full energy-flow techniques McPherson --Terascale Detector Development TRIUMF Town Meeting

  9. Detector Mechanical Needs, 2010-2015 + 8.4 FTE/year designers McPherson --Terascale Detector Development TRIUMF Town Meeting

  10. Electronics Needs, 2010-2015 ~ +100 k$ equipment (probe station, faraday cage for low noise tests, …) McPherson --Terascale Detector Development TRIUMF Town Meeting

  11. Outline of whitepaper (how long??) • 3. Canada at the Terascale • refer to NSERC LRP – William • past and future contributions from Canada: • 3.1 LHC,sLHC • 3.1.1 accelerator Chris + Rob • 3.1.2 detector - Colin + Gerald + William   • 3.2 ILC • 3.2.1 accelerator  - Dean + Nigel • 3.2.2 detector - Dean, Madhu, Mauricio • 4. Roles for TRIUMF infrastructure • explain how TRIUMF and NSERC/Universities work together – William • 4.1 Detector development   - Chris + Dean + Alain • detector design, simulation, engineering, construction • list a set of projects, indicate commonalities, indicate TRIUMF FTEs required for the work, indicate any new infrastructure required • 4.2 Electronics development - Colin + Leonid  - as above • 1. Physics of the Terascale   - Rob • The big questions in physics and how they are answered by TeV scale colliders • draw from and refer to many recent documents on the subject • indicate synergies between hadron and electron experiments • 2. Experiments at the Terascale • 2.1 Accelerators • 2.1.1 LHC  - Chris + Rob  - brief overview • 2.1.2 sLHC - Chris + Rob • parameters, timescales • 2.1.3 ILC  - Dean • parameters, design, timescales • 2.2 Detectors • 2.2.1 ATLAS  - Colin + Gerald • brief overview • 2.2.2 ATLAS upgrades for sLHC - Colin + Gerald • main challenges, current concepts • 2.2.3 ILC  - Dean, Madhu, Mauricio • main challenges, current concepts McPherson --Terascale Detector Development TRIUMF Town Meeting

  12. Other notes • Assume all production people from NSERC • Here: just TRIUMF infrastructure for design, development • Did not discuss, eg, renewal of electronics group basic infrastructure, computing hardware renewal, accelerator contributions ( plenary) in detail • But this is still essential to our program and needs 5YP inclusion! • Recommend review of other infrastructure (eg, clean rooms) considering detector development needs • Also clarify mechanisms for allocation of personnel / time, especially for outside users • Also discussed central role of TRIUMF in Geant4 support • With ~ 3 FTE in this area, could be world leading contributor • Short term, with ~ 1.75 FTE, leader in ILC/SLHC simulation detector design • White-paper draft by end of August McPherson --Terascale Detector Development TRIUMF Town Meeting
