The cheapest way to have generate a pulse of some x-rays is to use a low pressure discharge.
Such is source is of low brilliance and low photon flux but all you need is a capacitor, a vacuum chamber,
special formed electrode system and a thin exit window.

For the use under atmospheric pressure the charging voltage has to be some 10 keV.
For soft x-rays (useable only in vacuum) some keV would be sufficient.

The problem is your application :
depending on your sample the energy has to be adopted.
if you want some resolution (radiography) the source size should be smaller.
