Study on Space Radiation Effect and Ground Simulation Method of Light Flint Glass

The space radiation effect of flint glass(QF)is studied by using ⁶⁰Co gamma radiation facility.The performances of QF glass's sample changed with dose at two dose rate situation are obtained.The ground simulation test methods of the flint glass are discussed.The maximum exposure dosed is 100Mrad.The variation of sample properties with dose is discussed.An exponential function is proposed to describe the absorption increase when the total dose rises.The annealing experiments of QF glass at room temperature,343 K and 373 K were carried out,and the annealing rules of QF glass were summarized.The influence of annealing was applied to control the test time of optical glass after irradiation.
