  3. AOB/Questions

Notes:

ECAL Calorimeter:

  • Need to implement the small offsets that come from the survey.
  • Scoring plane is too far forward. 
  • Need a new detector to incorporate these changes: Modify current or create new detector?
    • Update the detector, currently at V1. 
    • Currently, the compact.xml does not reproduce the LCDD files that were created. This is for the 0.7 etc files.
  • We need to start doing some MC on the updated geometry.
  • Some work may be needed for the RF. Fit needs to be improved. This will require some software updates (evio->LCIO).

 

Hodoscope: 

  • Hodoscope geometry looks fine.
    • We will need to, eventually, compare the hodoscope outline against tracking.
  • Currently writing objects twice: CalHit and Generic Object.
    • The CalHit was missing  the position information: ix, iy, layer. 
  • Want to add a link between cluster object and hit objects.
  • Rafo is looking at the gains for different runs. There is luminosity dependence. Constants to DB.

 

Alignment:

  • Norman is continuing work on the SVT alignment. 
    • Local measurement is not persisted. 
    • Working on some infrastructure for getting the local position correctly.
  • Millipede ID indexing issue is fixed. - Already merged.
  • Dusting off the 2016/2016 procedures for getting the alignment parameters. Alexandra is working on procedures, scripts. Update at Collaboration Meeting.
