Crystals are used as a homogeneous calorimetric medium in many high-energy physics experiments. For some experiments, performance has to be ensured in very difficult operating conditions, like a high radiation environment, very large particle fluxes, high collision rates, placing constraints on response and readout time. An overview is presented of recent achievements in the field, with particular attention given to the performance of Lead Tungstate (PWO) crystals exposed to high particle fluxes.

The Panda experiment is a key experiment at FAIR -European Facility for Antiproton and Ion Research, which is in the development stage in Darmstadt (Germany). The physical program of the experiment is focused on the search for exotic particles, research on hadron spectroscopy, the structure of nucleons, nuclear-matter effects, hypernuclei, and in other areas. New experimental forms of matter predicted by theory -glueballs and hybrids -are of great interest. They have not yet been observed. The PANDA facility will be assembled in the storage ring of the HESR antiproton beam. Antiprotons with energy from 1.5 to 15 GeV will be accumulated in the ring. Up to 2·10 7 interactions/sec are expected on the internal hydrogen (cluster or corpuscular) target. In addition to the high luminosity of the experiment (2·10 32 cm -2 ·sec -1 ), the beam will be monochromatic. Because of stochastic and electronic cooling, pulsed stretching of the beam is expected to be at the level 10 -4 -10 -5 , which makes it possible to measure the mass of the particles with record high resolution 100 keV. Domestic institutes are participating in the development of the PANDA facility.The objective of the program of the PANDA experiment (Antiproton Annihilation at Darmstadt) is to search for new extreme forms of matter, such as the theoretically predicted exotic hadrons -glue balls and hybrids. Glue balls consist of gluons -the carriers of the strong interactions, while hybrids are a mixture of quarks and gluons.Aside from this problem, the program of the experiment includes research in hadron and nuclear physics. In particular, this is the study of narrow states of charmonium above the threshold of DD-meson pair production. Another important direction is the study of hypernulcei, including binary, and charm-nuclei, where a strange (one or two) or charmed particle "is implanted" into a nucleus instead of an ordinary nucleon. The search for new forms of matter in an interaction of anti-

We employed two independent methods to study possible damage to the scintillation mechanism in lead tungstate crystals due to irradiation by a 34 GeV pion beam. First, 10 crystals were irradiated simultaneously over 30 hours by a narrow beam, so that only a small region of each crystal was affected. We studied the effect of the irradiation on the light output non-uniformity. If a localized degradation was observed, it would indicate damage to the scintillation mechanism. Secondly, we detected light output using two phototubes attached to sides of a crystal. Since these phototubes detect scintillation light only from a small localized region, the effect of transmission loss should be minimal. We did not see any statistically significant evidence for scintillation mechanism damage with either method. The effect is consistent with zero, and the upper limit is 0.5% at 95% C.L.
