摘要

考虑功能元件的物理性质及其设计，对具有感应加热热离子阴极的透射x射线管进行了物理拓扑模拟。建模是基于使用ComSol的真空电子学和电动力学的物理基础。计算了电磁场、电流、温度和热电子轨迹的分布。电子轨迹的分析使得优化TRT拓扑结构和设计成为可能。

THE PHYSICO-TOPOLOGICAL SIMULATION OF A TRANSMISSION X-RAY TUBE WITH INDUCTION HEATING OF THE CATHODE

Physico-topological simulation of a transmission X-ray tube (TRT) with inductionally heated thermionic cathode is presented, taking into account physical properties of functional elements and their design. Modeling is based on physical fundamentals for vacuum electronics and electrodynamics using ComSol. The distributions of electromagnetic fields, currents, temperature, and trajectories of thermoelectrons were calculated. The analysis of electron trajectories made it possible to optimize TRT topology and design.
