Computerized glow curve deconvolution method is used to determine the number of peaks, the order of kinetics b, the activation energy $E_a$,frequency factor s and number of the trapped electrons n0 associated with the glow peaks in single crystal of $CaF_2$:Dy (TLD-200). Glow curve analysis indicate that the glow curve in the temperature region between room temperature and 250 $\circ$C can be best described as a superposition of six peaks. First five peaks are described by first-order kinetics and sixth peak general-order kinetic. The number of trapped electrons, activation energies and frequency factor for individual glow peaks are as follows: (Peak 1) $3x10^{13}$, 1.27 and $2.13x10^{17}$, (Peak 2) $6.3x10^{13}$, 1.01 and $9.2x10^{12}$, (Peak 3) $3.3x10^{14}$, 0.7 and $6.12x10^7$, (Peak 4) $2.4x10^14$, 1.14 and $3.28x10^12$, (Peak 5) $1.5x10^14$, 0.84 and $2.56x10^8$, (Peak 6) $2.4x10^{14}$, 0.98 and $1.76x10^9$.
