Light yield and surface treatment of barium fluoride crystals *
نویسندگان
چکیده
We report on a study of the light yield and surface treatment of barium fluoride (BaF2) scintillation crystals. Using a bialkali photocathode the photoelectron (p.e.) yield of BaF, crystals was measured to be 130 p.e./MeV for the fast components and 700 p.e./MeV for the slow component. A somewhat hygroscopic nature for the BaF, is found. Teflon film was found to be the best wrapping material for the BaF, crystals. The radiation damage of the BaF, crystals can be fully annealed under 5OO’C for 3 hours.

Optical bleaching in situ for barium fluoride crystals
This report presents results of optical bleaching for barium fluoride crystals to be used to construct a precision electromagnetic calorimeter at future hadron colliders. A practical technique for in situ bleaching by illuminating crystals with light from a UV lamp through an optical fiber is established. The light attenuation length of current production BaF, crystals can be set to around 200 ...
متن کاملInvestigation of Different Stages of Aluminum Fluoride Crystal Growth
Crystallization of Aluminum fluoride at atmospheric pressure has been considered. Structure, size and shape of crystals formed during the crystallization process have been investigated. By applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. The...

متن کاملOn optical bleaching of barium fluoride crystals
Barium fluoride (Baf2) crystals were considered by the GEM Collaboration, to be used in constructing a precision electromagnetic calorimeter at the SSC [1] . The key issue of using this crystal at the SSC is its radiation resistance [2] . An Expert Panel was assigned by the SSC laboratory to review the radiation damage problem of BaFz. The Panel met in December 1991 and again in January 1992 fo...
