Abstract
Organic scintillators are often chosen as radiation detectors for their fast decay time and their low $Z$, while inorganic ones are used when high light yields are required. In this paper we show that a para-terphenyl based detector has a blend of properties of the two categories that can be optimal for energy and position measurements of low-energy charged particles. Using 0.1% diphenylbutadiene doped para-terphenyl samples we measured a light attenuation length $\lambda = 4.73 \pm 0.06~\hbox{mm}$, a quenching factor for $\alpha $ particles ${Q_\alpha } = (10.7 \pm 0.6)$, and a rejection power ranging between $3 - 11\% $ for 660 keV photons, with respect to electrons of the same energy, depending on the signal threshold. A simulation based on FLUKA properly reproduces the experimental data distributions.
