BeAST Magnetic Field

The repository contains an ASCII file with the field map, a C++ class to handle it and a GDML model

Open solenoid design (no field clamps)

Homogeneous (less than than 4% variation) 3T central field in the TPC volume

Fringe field is tuned in order and minimize charge particle bending in the forward gaseous RICH volume (less than 1mrad RMS for 10 GeV/c particles up to 25 degree polar angles)

Field map originally produced by a collection of Open Source tools (Elmer, Netgen, ROOT)
