Detailed Description

Class for particle identification.

Author: M.Kozlov kozlo.nosp@m.v.m..nosp@m.your@.nosp@m.yand.nosp@m.ex.ru

Version: 1.0

The ERBeamDetPID identifies particle via selection ions from the limited area assigned by the time of flight between ToF plastics \(\Delta T\) and summary energy deposit in ToF \(\Delta E\). Then it calculates the Four-vector \((p_x, p_y, p_z, E)\) and initilise the projectile object determined by class ERBeamDetParticle.
In the first version of ERBeamDetPID class user should set mass of ion [MeV] for identification.
