The tracker design includes a compact silicon tracker with 5 layers in the central region and five disks per end. The tracker is expected to provide excellent ... WebNeutrons in the energy range 0.5–10 keV are called intermediate neutrons. These neutrons may also be called resonance or epithermal neutrons. Fast neutrons are those in the energy range 10 keV to 10 MeV. In this energy range, neutrons interact with matter through elastic collisions (i.e., billiard-ball–type collisions).
