Optimization of periodic temperature variation of a lithium tantalate single crystal in a pyroelectric accelerator for stable X-ray generation

Analysis of the X-ray spectra and curves of periodic temperature variation of a lithium tantalate single crystal shows that the shift in temperature oscillations is a negative factor that leads to unstable operation of the pyroelectric accelerator. However, there is a range of permissible displacements at which the generation of particles remains stable. Thus, it is necessary to monitor the implementation of the law of temperature change for the effective operation of the pyroelectric accelerator. The influence of the residual gas pressure and the amplitude of temperature oscillations on the discussed effect is also analyzed.
