Abstract

Testing techniques for detection of platinum micro-inclusions in the laser glass have been developed. Over 70 KGSS 0180 glass samples totaling ~ 400 cm³ have been tested. It has been shown that platinum-induced damage was absent only in 25% of glass melts out of the entire tested amount. An averaged concentration of inclusions was N_pt ~ 5 liter^-1. Concentration of micro-inclusions in the last KGSS 0180 batch is ~ 1÷2 liter^-1. To automate and reduce testing time for the entire blank volume of the active disc element (4-6 liters) an automated system for mapping Pt-inclusions during irradiation has been developed. The efficiency of the proposed QC methods has been demonstrated experimentally.
