Do X rays need to be created inside of a vacuume? Can they be made without a vacuum?

 

Do X rays need to be created inside of a vacuume? Can they be made without a vacuum?

They do not require a vacuum for their creation, but having a vacuum eliminates extraneous interactions that are not useful or interesting if the goal is to generate X-rays. The Wikipedia article, https://en.wikipedia.org/wiki/X-ray_generator
includes this quote:

A film of carbon nanotubes (as a cathode) that emits electrons at room temperature when exposed to an electrical field has been fashioned into an X-ray device. ​
