What mechanism is used for x-ray production in an accelerator unit?

The production of x-rays in an accelerator unit primarily involves a process where electrons are injected into a microwave system to be bunched and accelerated. This mechanism operates under the principles of particle acceleration and microwave technology.

In this context, electrons are introduced into a cavity where microwave radiation is applied. The microwave field creates oscillations that effectively 'bunch' the electrons together and propel them to high energies. As these high-energy electrons interact with a target material (often made of heavy metals like tungsten), they produce x-rays through a process called bremsstrahlung. This is essential for achieving the high-energy radiation used in various types of radiation therapy.

This method of x-ray production is particularly efficient in accelerator units because it allows for precise control over the energy output and the focus of the electron beam can be finely tuned. Such advancements in technology enhance the effectiveness of radiation treatment in medical applications.
