Understanding the Detector Structure

[Swathiu]

To have a deeper understanding of the concepts like Hits, Events, Module Id, Volume Id, we need to completely understand the structure of the TML Detector model used to generate the simulation.

1. Complete structure of TML Detector model with diagram and proper labeling.
2. This is followed by understanding the concepts of Hits, Events, Module ID, Volume ID and why it is required for path tracking of particles?

3. General Properties of the particles used in LHC

Truth File:
tx, ty, tz true intersection point in global coordinates (in millimeters) between the particle trajectory and the sensitive surface.-- What does intersection between particle trajectory and sensitive surface mean?

• What is the channel identifier [ch0 and ch1] which determines how much charge a particle has deposited depends?

• What does it mean to have hit id but particle id is 0 but there is charge deposition?

• What is per hit weight?

• meaning of location of production vertices.

The present algorithms rely on linear dynamics- What is the meaning of this?
Scale poorly with detector occupancy - meaning?
