  • Average radiation length of 4.83% X0 in region 2<η<5
  • Light tight TT box made of 400μm thick (Kevlar + graphite paper + epoxy)
  • Kapton (thickness = 100μm) surrounding the beam pipe to replace the current jackets
  • Smaller beam pipe hole @ 28mm (to check the maximum coverage gain)
  • New TT detector hierarchy and addressing (more readout sectors to address)
  • Sensors are placed at front & back of module alternatively to provide sufficient overlaps
  • Sensors with semi-circular cuts surrounding the beam pipe for maximum inner acceptance
  • Sensor positions are optimized to have overlap (minimal) & full coverage
  • Finer pitch in the bending direction of the cental region

Notes for Developers

Please make the reviewer aware of the code location and also provide them with an explanation of how the code works and fits into the LHCb software framework.
