Radiation resistance investigation of quartz glass KU-1

Abstract

Results of investigation of the quartz window radiation resistance to fusion reactor conditions are described. The tests of a few selected materials have shown that the best for a visible spectrum region is quartz KU-1 with a large hydroxyl (OH) content. In comparison with other tested types of quartz it has a lowest loss of the transparency, the lowest radioluminescence(RL) intensity and in comparison with other materials (sapphire, cerium glass and spinel) preserved its properties in the widest region of the optical spectrum after neutron, electron and gamma irradiation.
