“…On the other side, some drawbacks in using these crystal are found in the fact that their photon emission is only almost 10% with respect to the light emission of NaI(Tl) crystals and that, normally, after the production process they contain some Ra impurities, that are at the origin of a typical "background", constituted mainly by a group of alpha-particles (with energies ranging from 4.9 to 7.8 MeV), and in minor extent by -rays and electrons [4], [10]. An enhancement in the application of to medium energy physics arrived with the possibility to detect at the same time light charged particle (isotopically separated) and heavy ions (charge separation only), by just putting at the surface of the crystal a typical fast plastic scintillator (NE102A) [11], [12] exploiting the advantages of the phoswich technique [13], [14] and of the high time resolution [1]. The Argos forward wall, constituted by about 60 of such phoswiches, has already been successfully used for studying nuclear reaction mechanisms in experiments at intermediate energies [15], [16].…”

“…The basic material of a plastic scintillator is a plastic that contains some form of aromatic hydrocarbon such as polyvinyltoluene (PVT) or polystyrene (Bondansky & Eccles 1957). Generally, a plastic scintillator is produced by doping *Author for correspondence (hidehito@nirs.go.jp).…”
