Abstract
In this paper, we report an investigation on the
radiation damage effects induced by neutrons in large size crystal
scintillator: BGO, CeF_3, LYSO:Ce and PWO. The irradiations
were carried out by using fast neutrons from one ^(241)Am-Be
and two ^(252)Cf sources. The optical and scintillation properties
of these samples, including UV excitation and emission spectra,
longitudinal transmission, light output, decay kinetics and light
response uniformity, were measured before and after the irradiations.
The neutron induced photo-current was also measured,
and was used to estimate the readout noise under the neutron
flux expected by an electromagnetic calorimeter at a very severe
radiation environment. Because of its high light output and
excellent radiation resistance LYSO:Ce crystal is found to have
the smallest neutron induced readout noise as compared to other
large size crystals, indicating it is a good candidate material for
a future crystal calorimeter in a severe radiation environment.
