Plastic scintillator performance parameters

The performance parameters of the plastic scintillator vary depending on the matrix, the scintillation substance, and the second solute, the difference in the wavelength and the difference in scores. Therefore, the varieties of plastic scintillators are various and the performance parameters vary greatly.
The emission spectrum of the plastic scintillator is consistent with the emission spectrum of the scintillator, and the emission spectrum of the scintillator
different. When a wave remover is used, the emission spectrum of the plastic scintillator is consistent with that of the wave shifter.
The light output of the plastic scintillator increases with the increase of the concentration of the scintillator substance, and reaches an extreme value when the mass concentration is 1% to 4%. As the concentration continues to increase, the light output decreases. Adding 0.01% to 0.02% of the mass of the agent can dramatically increase the light output.
Large quantities of heavy charged particles or electrons are radiated over a long period of time, causing the plastic scintillator to be damaged and the light output to be reduced.
The energy response of the line attenuation coefficient of the plastic scintillator is shown in the figure.
