Cyclotron collimator time step
Summary
Cyclotron collimator needs that each particle has own time step
Steps to reproduce
Collimator in BANDRF cyclotron without acceleration: particulas_1000_xUyUzU_pxpypz.dat BField_0T_const.dat trackingColl.in
What is the current bug behavior?
In ParallelCyclotronTracker time step is not an attribute not null for each particle, so the simulations breaks in CollimatorPhysics::copyFromBunch, because stepWidth=0
What is the expected correct behavior?
dt[i] should be equal to general timestep
