Barcelona,7-8 Mayo 2009) R&D issues 19 Engineering low-mass vertex tracking system cooling pulsed power operation vibration due to Lorentz force in 5T More detailed tracking performance studies Effect of non-uniform B (6% Bz drop at the end) failure mode analysis Would probably require an engineering prototype in 5T magnet as the 2007 ILC Tracking R&D Review Committee pointed out. Would probably require an engineering prototype in 5T magnet as the 2007 ILC Tracking R&D Review Committee pointed out. Tracking algorithm requires 7 hits out of 10. So, one hit less will not degrade the performance very much. More study necessary for low pT tracks or those that have fewer than 10 "true" hits because of decays, secondary interactions, or V tracks. in-situ alignment via Frequency scanning interferometry and/or Infrared Transparent Silicon Sensors Hiro Aihara, TILC09

38 Forward Tracking at the next e+e- collider, presented by Alberto RUIZ JIMENO (Universidad de Cantabria) On behalf of Spanish Network for Future Linear Accelerators –A lot of activities in Spain on ILC detector and accelerators “ forward physics” oriented –Forward tracking is very important in many physics cases; –Pose great challenge: The material Hermetic coverage Significant background at smallest radii The unfavorable orientation of the magnetic field Abundant low momentum tracks – pattern recognition –For ILD, we are nowhere near the goal, and far from the performance of the central tracker Yulan Li: Vertex and Tracking Summary

39 A. Ruiz (Jornadas ILC. Barcelona,7-8 Mayo 2009) Forward Tracking at the next e+e- collider (cont.) R&D on Detectors, covering: –sensors: DEPFET pixels, 3D sensors, thinned microstrips, semitransparent microstrips. –FE electronics, development of DSM r/o chip. –mechanics: deformation and thermal analysis.

Barcelona,7-8 Mayo 2009) Silicon for Large Colliders Strong Spanish participation in DEPFET IFIC (since 2005)‏ USC, UB, URL, CNM (since 2008)‏ IFIC, IFCA (since 2005), UB, CNM, USC IFCA  EUDET member, several associates CALICE CIEMAT Madrid Forward Tracker Coordinated effort : - regular meetings - funding/projects - R&D interests - the forward tracker… Coordinated ILC detector- effort in Spain Barcelona U.

41 A. Ruiz (Jornadas ILC. Barcelona,7-8 Mayo 2009) Forward Tracking, Physics case: Conclusions e + e -  Z/  *  l + l - at the Z-pole has predominantly central final products. But ISR causes increasing fraction of forward-backward at larger center-of-mass energies 4, 6,and even 8-fermion abundantly produced with increasing center-of-mass energies. As e.g. t anti-t  W + bW - anti-b, rarely fully contained in the central detector Scalar electron production has a strong t-channel contribution, with final state electrons peaking in the forward-backward direction Final state fermions in di-boson production peaking in the forward- backward direction The same for Higgs boson production through vector-boson fusion Forward-backward region specially important for final states with electrons, but not only then Other channels not discussed here make a good case for forward tracking A. Ruiz, TILC09

42 A. Ruiz (Jornadas ILC. Barcelona,7-8 Mayo 2009) Tracking performance ILD: We are nowhere near the goal, and far from the performance of the central tracker (figure lines:  (1/p T )= 2.0×10 -5 ⊕ 1.0×10 -3 / (p T sin  (GeV -1 )‏,  r  = 5  m ⊕ 10  m/ (p T sin  ))!! Most of this is plain geometry: unfavorable orientation of the magnetic field (  (1/p T )), and large distance of the FTD1 to the interaction point (  r   TESLA ref for low polar angle :  (1/p T )= 1.8×10 -3 ⊕ 1.3×10 -2 / p T (GeV -1 )‏ A. Ruiz, TILC09

43 A. Ruiz (Jornadas ILC. Barcelona,7-8 Mayo 2009) Momentum resolution ILD momentum resolution Single muons in ILD00 Performance ~ stable down to 36 o Steep loss between 6-36 o worse forward performance is the result of a combination of (a) magnetic field orientation (inevitable within 4  detector geometry)‏ (b) loss of # of measurements in TPC 100 GeV 10 GeV 1 GeV ILD00 A. Ruiz, TILC09

44 A. Ruiz (Jornadas ILC. Barcelona,7-8 Mayo 2009) Momentum resolution Momentum resolution for electrons (remember t-channel!!)‏ Ongoing study (Jordi Duarte, IFCA): generate single-electron samples (private, but available for those interested)‏ compare tracker-only momentum resolution of single electrons with the LOI results for muons Understand tracker-parameter dependence  material! 10 GeV e - 10 GeV  - ILD00 full simulation A. Ruiz, TILC09

45 A. Ruiz (Jornadas ILC. Barcelona,7-8 Mayo 2009) 100 GeV 10 GeV 1 GeV ILD00 a=5,b=10 Impact parameter resolution Unprecedented precision (small pixels, 20x20  m 2 )‏ Strongly reduce the multiple Coulomb scattering term (material: 0.1 % X 0 / layer ~ 100 mm Si)‏ b a 100  m 10  m ILD vertexing performance central : a~1.7 mm forward: performance significantly worse than extrapolation of barrel formula with a=5,b=10 a (  m) b (  m.
