1. Introduction. Currently, simultaneous detection of three types of radiation, i.e. gamma-rays, fast neutrons and slow neutrons, is possible via detectors that combine sensitivity to fast neutrons with neutron/gamma (n/ γ) discrimination capability and a high thermal neutron capture cross-section.All of these features can be provided by organic scintillators [1].
can be used for particle identification. For example, by utilizing a pulse shaping network that makes the timing of the output pulse dependent on decay time, the particle distribution is transformed into a time distribution that can be digitized directly. Example: n -γ discrimination P. Sperr, H. Spieler, M.R. Maier, NIM 116 (1974)55

The system can detect when the ambient light level drops below a certain threshold, triggering the lights to turn on. Similarly, it can sense when the ambient light level increases, signaling the lights to turn off. This means that the lights are only on when necessary, which promotes energy efficiency and reduces your power bill.
