Ha. Klose et al., ON THE MEASUREMENT OF DEGRADATION AND RECOVERY OF SCINTILLATING PLASTIC FIBERS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 135(1-4), 1998, pp. 555-559
Scintillating plastic fibres find an increasing number of applications
in different fields ranging from elementary particle detection to rad
iobiology. One of the yet open questions is the long time stability of
these fibres, For this sake, experiments have been performed under 2
MeV electron and under 70 MeV proton irradiation, in a way so that the
counteracting effects of radiation-induced degradation and thermal de
fect annealing at room temperature are well separated in time scale. T
hus, it became possible to determine them both, and, furthermore, to e
stablish predictions for the fibre efficiency under any operational co
ndition. The fibre degradation scales with the accumulated electronic
energy density. (C) 1998 Elsevier Science B.V.
