The assessment of the stress state of scintillating crystals is an important issue for producers
as well as users of such materials, because residual stress may arise during growth process …

A reliable and noninvasive measurement method for the inspection of naturally birefringent
transparent media is presented in this paper. It allows us to achieve a spatially resolved …

The tetragonal PbWO_4 (PWO) is one of the most important scintillating crystals, being used
both in the Compact Muon Solenoid (CMS) experiment at the European Organization for …

An exact knowledge of the mechanical and optical properties of crystals allows not only for
theoretical advances, but it is also a useful tool to asses crystal quality in the technological …

The great interest in scintillating crystals, is related to their applications in the high energy
physics, biomedicine and security. For this reason a complete characterization and …

In conventional conoscopic interference patterns of optically anisotropic materials the
isochromatic interference fringes are inherently masked by the dark isogyres. We prove that …

Conoscopic analysis of interference fringes is one of the most useful tools for investigating
the mechanical properties of a crystal. These fringes are generated by a surface of constant …

The mass production of new generations of high quality and very performant scintillating
crystals requires sophisticated measurement systems and inspection tools in order to have …

Among scintillators, the PWO is one of the most widely used, for instance in CMS calorimeter
at CERN and PANDA project. Crystallographic structure and chemical composition as well …
