Where we are Fall 2007: Call for LOIs was made by ILCSC Mar.2008: IDAG formed & 3 LOI groups known 2007 RDR 2008 2009 Mar.2009: 3 LOIs submitted Summer 2009: IDAG recommendation Oct 2009: Work plan of the validated groups Mar:2009: IDAG began monitoring the groups End 2010: Interim report to be produced 2010 Now 2011 2012 End 2012: Detailed Baseline Design Report 2010/11/15 S.Yamada SiD WS@Eugene 2
The Detailed Baseline Design DBD - The Nine Points 1.Demonstrate proof of principle on critical components. When there are options, at least one option for each subsystem will reach a level of maturity which verifies feasibility. 2.Define a feasible baseline design. While a baseline will be specified, options may also be considered. 3.Complete basic mechanical integration of the baseline design accounting for insensitive zones such as the beam holes, support structure, cables, gaps or inner detector material. 4.Develop a realistic simulation model of the baseline design, including the identified faults and limitations. 5.Develop a push-pull mechanism, working out the movement procedure, time scale, alignment and calibration schemes in cooperation with relevant groups. 6.Develop a realistic concept of integration with the accelerator including the IR design. 7.Simulate and analyze updated benchmark reactions with the realistic detector model. Include the impact of detector dead zones and updated background conditions. 8.Simulate and study some reactions at 1 TeV, including realistic higher-energy backgrounds, demonstrating the detector performance. 9.Develop an improved cost estimate.
Guidance for DBD Presenters A list of critical R&D that remains to be done in time for inclusion in the DBD at the end of 2012. Resources (personnel, financial, material) that you need to achieve completion of the critical R&D and any problems that you see their provision. A best-estimate of the timeline for the critical R&D. A re-statement of the baseline technology and the expected status of options. The status of the conceptual engineering. The status and expected evolution of the subsystem in the SiD simulation.
DBD Planning Thank you! to those who provided the reports, DBD related planning information at this meeting. It is clear that predicting where we will be in detector R&D, simulation, conceptual engineering in 2012 is not so easy this meeting has given us a first view. However, in order to make progress we need to fix certain deadlines: - Finalize detector optimization - Freeze global parameters - Complete final DBD simulation software - Complete testing of simulation, reconstruction - Begin event generation for benchmarks - Begin analyses of benchmarks
Detector Optimization MIT group engaged in systematic study of HCal variants based on simplified SiD geometries using slic + SiD PFA (R. Cowan report at next PFA mtg.). extending studies done for the LOI by Marcel Stanitzki using Mokka + MarlinReco (SiD-ish) primarily studying HCal depth and layout. Should we engage in a similar global exercise? Tracker layouts Detector aspect ratios Ecal design HCal absorber materials, layout, readout technologies. 6
SiD Optimizations ECal resolution could be improved with thicker Si ECal thickness ( cost) could be reduced ECal/Hcal separation is somewhat artificial Excellent high energy , e+/- response with analog HCal Octagonal Barrel geometry reduces number of phi cracks reduces amount of overlap in EM staves Is Tracker layout Optimal? Pixel Tracker option very attractive Proposal: Goal to complete optimizations by SiD Workshop in Summer 2011 7
Reconstruction for the DBD Need to solve tracking problems. Need to implement corrections for additional realism . Run on sample at 1 TeV cm to identify additional problems. Verify algorithm improvements carry over to sidloi3. Goal: Completion of reconstruction software end 2011

Tracking LOI demonstrated that an all-silicon tracker with ~10 hit measurements would give excellent performance at the ILC Substantial effort in developing a more realistic detector simulation is bearing fruit Forward tracking efficiency problem appears to have a kludge fix that is working Other issues: Charge asymmetry probably requires the Kalman filter fitter to be completed Large hit error in pixels may be due to noise setting being too large Duplicate tracks appear on occasion no easy solution Some events take a long time to complete no easy solution Misplaced hits too few strip / pixel readout bits?? Some of these issues require focused / concentrated effort difficult to achieve with present manpower situation Richard Partridge 11
Vertex + Tracking DBD Planning Re-instate the regular vertex+tracking meetings. Benefit from work deriving from CDR. Improvements for CDR drive timescale Any residual issues for DBD completion by end 2011.
HCal DBD Planning global issues - Depth inner radius fixed, outer radius? - N , number of layers optimization? By Summer 2011 - Cracks/stringers more studies - Projective/non-projective boundaries? - Module design (barrel, endcap) how many modules along barrel length? Module shape(s) in endcap? - Engineering layer design/deflections, module design integrity, support from coil - Services allowing space, dead material - Electronics - Power Several items affect completion of simulation end 2011
