Hi friends,
Can anyone help me regarding Xray tubes power supply design.
Pls tell me why high voltage pwr supply is required for x ray tubes.
What the specifications required for the design of this power supply.
Artlav, Thank u very much for your reply.
I need some more info on this, why that much of voltage is required?? With low voltages why it is not possible to produce X-rays? Is there any other tubes which can produce X-rays with low voltages??
I need of high voltage power supply design also?
Please help me in this regard.
Supply voltage is directly related to x-ray energy and penetration ability. Below 10 to 15 kV, there isn't much effect. https://en.wikipedia.org/wiki/X-ray
The way to produce X-ray is by acceleration electrons. Electron have a negative electric charge. So by applying a very high tension on 2 plates the electron will travel from one plate to the other. The reason why you need high voltage is because you need to accelerate them really fast because usually you have a small distance.
We all know F=m*a. If you want a big "a" with a "m" constant, you need a big "F".

What kind of photon energy do you want, eV, from
decelerating the electron? That's what you've got to
put in so you can decelerate it later. N eV divided by
1 electron, well, there's your math.

If you want to try , find a very old Color TV; on the first models there was no anode voltage regulator and so was quite easy to increase the voltage and go above 30 KV, starting the emission of X-RAY.
A few hundred kV on a giant stack of capacitor pucks,
in a big ol' tank of SF6, makes a nice little burst that
hardly hurts anything. At least, anything that didn't
deserve it.
