Agenda:

  1. Ecal implementation for SLIC and lcsim -- Jeremy.  (powerpoint ppx or pdf ) 
  2. HPS Software Intensive, draft schedule -- Maurik.   (pdf )

Notes of the discussions during the meeting:

  1. The time profile of an event will be important. How will we handle energy from previous time windows leaking into the current one?
    1. The time profile of the ECal response will go into the analysis end, not the simulation.
    2. Some tools already exist to overlay background. There tools can also deal with the timing issue.
    3. This is something we will need to do, but it is not critical right now.
  2. Will the coordinate choice for the simulation and analysis change from "collider" geometry (magnetic field along z, so z is pointing up) to "lab scattering" geometry (z is along the beam, y is pointing up)?
    1. Some thought has already gone into this. It can be done while leaving the tracking code untouched, by rotations before and after the tracking code (these would be fast rotation, since they are over 90 degrees).
    2. Probably will be done at the next junction where the coordinate system plays a large role.
  3. What are the best plots for comparing/validating the two simulations, SLIC and GEMC?
    1. Maurik will dig up some of the plots used to understand the GEMC simulation, or create new similar ones. 
    2. It will be very useful to look at the energy deposition of single photons (and then single electrons) in the ECal.
