Highlights from the Tracking Sessions
12 talks in three sessions
Rough accounting:

Topics sampled for summary:
• Results from TPC Large Prototype
• SiD Tracker Performance (simulation)
• TPC Pixel Readout
• TPC Backgrounds
• Charge Division for Silicon Sensors
• “Alignment Aware” Si Sensors
Plus much more (apologies…)

Large TPC prototype
30 cm longitudinal driftImmersed in 1.25 T Bfield
Readout:
Double/triple GEMMicroMeGas
+Resistive PadsPixels (TimePix)

From MediPix to INGRID (Jan Timmermans, NIKHEF)
TimePix chip plus deposited grid plus stand-offs: INGRID readout system (gas-gain plus 50 m pixelated readout)
Working towards ~10cm x 10cm array
Full instrumentation of ILD TPC requires~1010 channels (same order as VXD)

SiD Tracker Performance (full-ish simulation)
Full GEANT simulation plus strategy-based pattern recognition (Richard Partridge)
Near-perfect efficiency over full range in pT , |cos|
Top pair events at Ecm = 500 GeV

SiD Tracker Performance (full-ish simulation)
Momentum resolution probed with single muons
Consistent with (pT) = 0.2% 2.810-5 pT at 90°

Charge Division for Silicon Sensors
• SCIPP built discrete resistive network (SiD “charge division” sensor not available• Benchmark PSpice simulation
Observations:• Longitudinal resolution independent of R; grows as C
• Noise dominated by network, not amplifier
• Achieve resolution of ~6% of sensor length
• Z ~ 6mm for 10cm sensor
