Status of Crystal Clear Collaboration activities on scintillators

Since about 10 years, the Crystal Clear Collaboration at CERN works on systematic investigations of new scintillating crystals and their application in science and industry. A large amount of new type scintillators had been characterised and optimised in terms of emission spectra, light yield, production yield and radiation hardness. As a result, one of those crystals, PbWO₄, was chosen to be the baseline solution for the CMS electromagnetic calorimeter at CERN and is actually produced in industrial scale with a quantity of about 1000 crystals per month. Another baseline of actual research interests in Crystal Clear is the construction of a PET-scanning prototype made of small, high light yield crystals for future medical applications. As a result of the different research activities on scintillating crystals, a website is currently under construction, which provides access to a large crystal database. Beside general and methodological informations on scintillating crystals, the database will contain a large amount of data gained so far about investigated crystals, including light yield, emission spectra, radiation hardness and mechanical properties. The actual status of this website is presented
