This system manages the fiducial volume and provides essential transformations and utilities for efficient event reconstruction and analysis. It supports wire-based readout systems and accounts for dead regions while offering flexibility for future extensions.
Components
1. Boundary Definition Variables
Define the limits of the fiducial volume in 3D space.
Example: (xmin, xmax), (ymin, ymax), (zmin, zmax) for Cartesian boundaries.
2. Coordinate Transformation: Wire-Channel to 3D Space Points
Converts wire-based readout (wire, channel) information into corresponding 3D spatial coordinates.
Uses predefined geometry mappings between wire planes and the detector volume.
May involve:
Plane-specific offsets and rotations
Mapping function: (wire, channel) <-> (x, y, z)
3. Dead Region (Channel) Management System
Identifies and manages channels that are non-operational or problematic.
Stores dead channels/regions in a look-up table or mask.
Ensures these regions are excluded from reconstruction algorithms.
4. Transformation System: Reconstructed Position to True Position
Provides transformations between reconstructed positions and true physical positions.
Requires knowledge of T0 timing for each cluster to account for drift corrections.
Example correction model:
true_position <-> reconstructed_position given T0
Basic Utility Functions
1. Check if a Point is Within the Fiducial Volume
2. Check if a Point is Within a Dead Region
3. Adjust Cluster Point Location with T0 Timing and Correction Function
