Requirement list #1

Open yramachers opened 2 years ago

yramachers commented 2 years ago

Attempt a list of requirements. Add as code develops.

Bespoke electron transport (magnetic field, solve ODEs)
implement options for primary event generator: (a) tritium beta decay generator; (b) single, monoenergetic electron
Score Voltage(time) in (all) antenna, not trajectory points.
need 'test.gdml': set up pyg4ometry gdml creation using python.
check physics list for G4 11 - still working? Check also new single scatter physics list in G4 11 - equivalent?
ROOT output required

Geometry challenge:

N Antenna in cylindrical arrangement - mark with auxiliaries = easier than defining and asking antenna volumes in geometry. Auxiliary information on N angles since we can ask the G4Tubs for its inner radius.
Eventually need geometry from CAD drawings = no volume definition for individual antennas (G4TesselatedVolume), ergo, again, define rather with auxiliaries and assume cylindrical symmetry. May well require radius as additional information to angles.
Antenna information (number N and locations) need to reach output definition objects and scoring in tracking action.

Skeleton requirements implemented, compiles, and runs for test case. primary event generator, done + test electron at 90 degrees from origin. Required max/min step limitations and max time limit implementation. Scoring, done test.gdml, done Physics list check, compiles fine, content check - to be done. root output, done antenna with auxiliaries, done, but currently restricted to cylinder surface around origin, retrieval of radius done.

Physics wish list for new features: Missing radiation energy loss implementation, pure Lorentz force currently. Permit choice of magnetic field types, predefined, calculated and 3D map from file. More realistic geometries, add some optional GDML files beyond test.gdml. More flexible antenna placement. Allow more antenna types, aka response function implementations.

Acceleration energy loss: done Choice of B-field: done [uniform, analytic bath tub trap and output file from COMSOL - read as gziped CSV file.] Flexible primary particle generator added: the GPS. Run timing output for benchmarking: done

Realistic geometry and B-field map missing, all made-up preliminary at this stage, v.01-beta
