Double-Mirror MPEP
Schematic of the double mirror collection system, which is featured with increasing magnetic fields on both ends of the device. The resonant particles with higher perpendicular energy are reflected by both mirrors and are trapped inside the separation region. The non-resonant particles travel directly through the device to the dump collector.
