Built-in command scoring

Implemented using MultiFunctionalDetector/PrimitiveScorer/SDFilter UIcommands operate scoring conditions A 3D voxel geometry is constructed in a Parallel world volume. Supports visualization of scored results

Testing codes

Test codes◦ Comparison of scored results

between scoring algorithms SensitiveDetector versus PrimitiveScorer

Confirmed for track length, energy deposit.

between scoring geometries Mass geometry versus Parallel geometry

Check on tracking/stepping

Statistical analysis

Current PrimitiveScorer accumulates only a quantity.◦ It should provide statistical error for the quantity.

With the contribution by Giovanni, ◦ New class “G4StaticDouble” will be introduced to

calculates the average and the RMS of the quantity in a event.

The modification for this updates is simple. Replace G4THitsMap<double*> to

G4THitsMap<G4StaticDouble*> Output format and documentation has to be modified.

Statistical information

Upgrades of Built-in command scoring◦ Visualization and file output are given in unit

specified by users.◦ Cylindrical volume with 3D structure, (i.e. z,phi,R)

is supported.◦ Scoring under magnetic field is working.◦ Statistical error will be provided.◦ The test codes for checking scoring results will be

prepared.
