physics question plz help?

Question

can anyone compare the xray production in the xray tube VS a linear accelerator?

Answer 1

I'm not sure what the question is, as just about all X-ray tubes contain linear accelerators.

Linear accelerators can be used for purposes other than generating X-rays, so in that sense they are a larger category.

X-rays can also be created by synchrotrons, where the electrons move around a closed loop:

This production technique is significantly different in two important ways:

1. It is much more efficient, so higher powers are much easier to achieve.

2. It allows for much better control over the frequency or wavelength of the X-rays
