The heating properties of LaB6 and CeB6 cathodes are investigated against the Back Bombardment (BB) effect in thermionic RF guns by using numerical calculations of the stopping range and the heat power deposited inside the cathode materials. Then, the change in the cathode temperature and the corresponding change in the current density during the 5.5 µs macropulse are determined by solving two differential equations. The simulation results show that the change in the current density during the macropulse for LaB6 was two times higher than that for CeB6; hence, the effect of the BB electrons in CeB6 is less than it is for LaB6

Here, we apply a recently developed technique to separate a composite thermoluminescence (TL) glow curve into its individual components and to evaluate the trap parameters of the individual TL glow peaks. These parameters include the order of kinetics b, the activation energy E (eV) and the frequency factor S (s−1) or the pre-exponential factor S″ (s−1). Recently, a general equation was developed to estimate the order of kinetics b. The characteristic point of this equation is that any set of three data points in a TL glow curve can yield b. Using this characteristic, an improved procedure was suggested to separate a composite glow curve, which includes several overlapping peaks, into its individual components and to obtain the trap parameters of the individual glow peaks. The method was applied here to analyze and determine the trap parameters of the TL glow curve of the promising TL dosimetric material, double potassium yttrium fluoride (K2YF5) doped with praseodymium ions (Pr3+), in response to γ-irradiation.
