The spectral and kinetic parameters of electron-pulse-initiated transient absorption of oxygen-doped Ca,F2 crystals were studied using pulsed spectrometry with a nanosecond time resolution. It is shown that the formation of a MA - color centers in CaF2-0.01M%CaO crystals occurs by thermally activated diffusion of the vacancies. Activation energy of MA + color centers formation process of 0.4 eV is established.
