Linear Accelerators
The four basic components of an X-ray producing machine include:
- a source of electrons
- a vacuum within which the electrons are accelerated
- an energy source which cause the electrons to be accelerated
- a target made of a high atomic number, high melting point metal
In the linear accelerator, these components are specifically:
- an electron gun such as is found in the common TV
- a long (0.5-1.5 metre) hollow copper pipe with various tuning compartments.
- microwaves such as those used to warm dinner, but tuned to the frequency of the electron.
- a tungsten target.
Of course there are many more components and control systems associated with the machine than these but these are the basics.
