Detailed Description

-*- C++ -*-

Package: GeneratorInterface/GenFilters

Description: Event filter for generated particles reaching a certain cylinder surface (around z-axis).

Implementation: Assumes particles coming from outside of defined cylinder, but might work also otherwise. Uses SteppingHelixPropagator and IdealMagneticFieldRecord.
