提出了计算单晶和双晶热释电加速器中的电势和场强的方程的推导。单晶系统的此类表达式在文献中已得到充分证实，但推导很粗略。我们提供了单晶系统的严格推导，并扩展了这种物理理解，导出了双晶系统中势和场的表达式。通过有限元建模验证了表达式并与实验结果进行了比较。这有助于更好地了解热释电加速器。
Derivations for equations for calculating the potential and field strength in both single-crystal and two-crystal pyroelectric accelerators are presented. Such expressions for the single-crystal system are well established in the literature, but with cursory derivations. We provide a rigorous derivation of the single-crystal system and expand upon this physical understanding to derive expressions for the potential and field in a two-crystal system. The expressions are verified with finite element modeling and compared with experimental results. This allows for better understanding of pyroelectric accelerators.
