Resolutions are studied with the mono-energetic showers.
- Energy resolution: stability of energy(-related) deposition in ECAL
- Intrinsic resolution proportional to
$1/\sqrt{E}$
- Requires enough length of passive material (e.g. tungsten)
- Leakage contribution
- Energy-independent contribution
- Intrinsic resolution proportional to
- Position resolution: Based on position reconstruction from
- Position-related energy resolution:
