医用电子直线加速器是生物医学上一种用来对肿瘤进行放射治疗的粒子加速器装置,而沃特塞恩固态微波源是医用电子直线加速器里面的一个重要组成部分。

The High Energy Photon Source (HEPS) is also a type of linear accelerator. As a linear accelerator, it is a room-temperature linear accelerator approximately 49 metres long. It serves as the source of electrons and the first-stage accelerator, used to generate electrons and accelerate them to 500 megelectronvolts (MeV). It consists of equipment such as an electron gun at the end, a focusing unit, an acceleration structure, and a microwave power source.

A free-electron laser is a device that uses a free-electron beam to generate highly coherent radiation. It employs a fixed-frequency, high-power microwave source to accelerate electrons, enabling its widespread application in fields such as metallurgy, mineralogy, and biomedicine.
