HFT Integration: Task List

  • Make hits available for Sti tracking
    • Restore PXL sensitive volumes as one volume per ladder. This configuration seem to make more PXL hits available for tracking then the one with one sensitive volume per sensor - Jonathan
    • Restore IST sensitive volumes. Contingent on implementation of inactive volumes
    • Are we loosing PXL hits with smaller active material volumes?
    • Is the Z coordinate of the active volumes ignored?
  • Make sure Sti HFT geometries can be reproduced with corresponding BFC options
    • Need a better way to pass BFC options to Sti classes
  • Understand the effect of the beam pipe on tracks
    • Create option for no beam pipe (asked by Gene). This check is critical for the inner PXL layer which may overlap with the beam pipe.
    • Confirm that Sti tube volumes cannot be created off center.
  • Issues with TGeo to Sti geometry translation
    • Investigate X -> -X reflection - Dmitri
      • The problem seems to be pertinent to visualization stage only. I swapped X and Y in StiDetectorVolume.cxx and the final result shows correct positioning of the volumes
    • Fix incorrect Sti volume rotation due to ambiguity in normal vector direction - Dmitri
      • A cleaner definition of Sti planar volumes with normal and central vectors helped. See Sti/StiDetectorBuilder.cxx
  • Understand grouping of ROOT volumes in a single mother volume. This may help to ease the creation of mother volumes which can be passed to the material averaging routine StiVMCToolKit::LoopOverNodes
    • Utilize volume grouping for IST high-z cable material
    • Utilize volume grouping for long PXL boxes with cables (PSCL, PSCK)
  • PXL inactive material
    • Material between the layers. Currently, we have a problem: From Gene's study only first sector has material
    • Consider extra material in the pixel support tube (PSTM)
  • IST inactive material
    • Resolve issue with IST enclosed volumes - Yaping
    • Lots of cables in -230 < z < -50 region (ICXX volumes in IDSM)
    • Too many Sti volumes?

  • BFC option with existing name can be added to the list of options causing duplicate entries and confusion. Proposed solution: Overwrite the previous value and print a warning in the log
  • Revive the study with conversion photons to directly visualize the real detector materia - ?
    • Check against the currently implemented ROOT TGeo geometries
