1. CLIC CDR in relation to SiD Lucie Linssen SiD discussion at IWLC CERN October 18 th 2010 1 LL, SiD meeting at IWLC, 18/10/2010

2. Special CLIC requirements Lucie Linssen SiD workshop, Argonne June 6 th 2010 2LL, SiD meeting at IWLC, 18/10/2010 Slide presented in Argonne June 2010

3. Some requests to SiD for the CLIC CDR preparation We want to continue working in a good relationship with SiD ! The support we request from SiD for the CLIC CDR will be mostly in the domain of: Support/consultation on software tools and simulations Editing support: –main editor Harry Weerts, (Marcel Stanitzki) –chapter editors: NN, Marcel Demarteau, Tim Nelson, Andy White, Marco Oriunno, Jan Strube, Marty Breidenbach Some help with the cost All other help is most welcome ! CDR Authorship The CLIC CDR will be based on vast amounts of work, previously carried out by members of SiD. All SiD members will be given the opportunity to sign the CLIC CDR. 3LL, SiD meeting at IWLC, 18/10/2010 Slide presented in Argonne June 2010

4. Support/consultation on software tools and simulations: Generator level –We would like to participate in the current effort of exchange of information between ILD and SiD, and in the attempt to automatize some of the procedure Grid production –Support and exchange of information (we will use DIRAC tool) –Help with issue of duplicate “ILC VO” ? CLIC_SiD CDR baseline –Based in sidloi3 SiD tracking tools –Continued consultation/help with adaptation of tracking tools Particle flow –Continued help interfacing PandoraPFA_new to the SiD software –Support during the debugging/checking/adaptation phase Physics analysis –Support and help for analyses that resemble prior SiD work 4LL, SiD meeting at IWLC, 18/10/2010 Slide presented in Argonne June 2010

5. 5LL, SiD meeting at IWLC, 18/10/2010 CLIC “editing” status Status of CDR preparation following dedicated meetings for each of the chapters

6. Event generation and grid production Since June: Participation of CLIC (Stephane Poss, Marco Battaglia) in “ILC common Monte Carlo data subgroup” (Tim, Akiya, Mikael B.)=> advice and streamlining of tools and methods Thorough assessment of gg=> hadrn background generation by Tim Barklow and Daniel Schulte Grid production using Whizard (ILCDIRAC, Stephane Poss) Very good progress. Thank you very much ! Continued collaboration will be highly appreciated Link to USA version of “ILC VO” still missing. 6LL, SiD meeting at IWLC, 18/10/2010

7. SiD tracking Since June: Visit of Christian Grefe to SLAC => with help of Rich Partridge and Norman Graf a number of tracking issues were solved. On the CLIC side, Christian Grefe and Blai Pie Valls use/assess SiD tracking for the CDR. Tracking issues related to muon ID (PFO, Pandora adaptations) => follow tracking in flipping B-field. => Currently there are still SiD tracking issues on “critical path” for the CDR. LCFI optimisation (b’s from light Higgs decay) at high energy currently ongoing by Tomas Lastovicka (Prague). Continued help from SiD tracking experts strongly needed. Planned visit of Norman Graf and Jeremy McCormick to CERN, first week of November (for outstanding tracking and PFA issues). 7LL, SiD meeting at IWLC, 18/10/2010

8. Pandora PFA and SiD Since June: Essentials of Pandora framework in SLiC seem to work. Thanks to work of Norman Graf et al. in collaboration with Cambridge team. Performance assessment, calibration and debugging: –Currently part-time involvement of: Marcel Stanitzki, Jan Strube, Peter Speckmayer, Christian Grefe, Angela Lucaci-Timoce Pandora PFA use of SiD detector is currently restricted to analog scintillator-based HCAL option Full check-out and optimisation of Pandora PFA in SiD is on the critical path for the CDR. Additional resources are required. (Jet energy calibration, energy resolution, particle ID), etc. 8LL, SiD meeting at IWLC, 18/10/2010

9. ~6.2m 9LL, SiD meeting at IWLC, 18/10/2010 CLIC_SiD simulation geometry (1) Changes to the ILC detectors: 20 mrad crossing angle Vertex Detector to 25-30 mm inner radius, due to Beam-Beam Background HCAL barrel with 7.5 Λ i with 1 cm tungsten plates HCAL endcap with 7.5 Λ i with 2 cm steel plates Forward (FCAL) region adaptations, including QD0 support and stabilisation z=0 ~7.0m “CLIC_SiD”

10. CLIC_SiD simulation geometry (2) 10LL, SiD meeting at IWLC, 18/10/2010

11. CLIC_SiD simulation geometry (3) Input from SiD management required to guide choice on: HCAL technology option for simulation model CLIC_SiD –Crucial to have working software very soon (including PFA performance) for the model chosen Vertex detector layout choice –See IWLC talk of Dominik Dannheim –Layout choice, # material, pixels size, analog/digital readout 11LL, SiD meeting at IWLC, 18/10/2010

12. Timeline simulation/reconstruction tools readiness for CLIC CDR 12LL, SiD meeting at IWLC, 18/10/2010 … extracted from latest minutes of CDR Benchmark working group Deadline=now for defining geometry and for readiness of simulation/reconstruction

13. CLIC CDR benchmark studies There is an imbalance between channels assessed for CLIC_ILD and CLIC_SiD 13LL, SiD meeting at IWLC, 18/10/2010

14. CERN LCD group and ILC DBD The CERN LCD group plans to participate in ILC DBD efforts (SiD and ILD) after the CLIC CDR –Fair sharing of efforts between ILD and SiD –Preference for common issues SiD/ILD/CLIC –The more similar the software frameworks get, the better for all of us. We currently see participation in the domains of: –Adaptations of ILD and SiD for the 1 TeV case –Benchmark studies –DBD editing CERN LCD resource level for dedicated DBD work still to be defined CERN LCD is currently preparing a hardware R&D program (tungsten HCAL, CLIC vertex detector technology, solenoid R&D, QD0 stability tests, power pulsing –Opportunities for collaboration with ILC in these areas 14LL, SiD meeting at IWLC, 18/10/2010
