The present disclosure relates to a particle and energy detection system. More particularly, the present disclosure relates to coherent particle generation/detection devices configured to detect a plurality of particles (or energy quanta) which are caused to be combined by superposition upon impacting the detector and imparting a portion of their kinetic energy to the detection process. Additionally, a low power particle generating system that uses a particle generator device configured to generate a plurality of excitation signals which are caused to be focused and impinge upon a separating mechanism is provided so as to direct the particle beam to optimize the system's detection capability.
