Meeting 2015 08 07¶
General Considerations¶
Theoretical radius: ~ 38 [mm]
Radius = (M/c^2) * gamma * v/ B = 0.5109989 * 22.366272 *0.999 * 1000 / 299.7922458 ~ 38.0854 [mm]
The relative error in each dimension should be: RelativeError = RelativeTolerance * Radius
For G4 we assume temporarily that RelativeTolerance = Epsilon (maybe we should convert it from 3D to 1D for each axis)
For PD we know that RelativeError = DeltaQrel
All PD simulations with QSS3 method.
The simulation simulates until trackMaxLen = 100m or time_max = 333.9ns
epsilonMin = epsilonMax = 1e-3
stepMax = 20mm
