Time-of-flight scintillation spectrometer of charged particles with a subnanosecond time resolution

A time-of-flight spectrometer based on a fast plastic scintillator was developed to study the spectral and angular distribution of charged particles emitted from laser-produced plasmas. The measured time resolution of the spectrometer was ∼0.3 ns, which made it possible to observe the fine structure in the spectrum of protons originated from the back surface of the target in experiments on the SOKOL-P laser facility.
