How the hell it maintains high vacuum with bearings and shaft going through the glass? Or it is only magnetically copouled with outside without shaft protruding?Does it stop supplying power when one wants to start x-ray production? I would guess magnetic field from the motor would influence trajectory of electrons from the kathode, and make x-rays of lower quality (energy spread and poorer colimiation).

It's magnetically coupled. I don't know if the rotor power supply switches off during x-ray usage - that's a good question. Maybe. It would be no problem at all to switch it off because the anode will rotate very very long once it is turning. I tried it... 1 hour easily without even slowing down much.

How did you wire up the filaments and rotating anode. I'm an xray tech and have 4 tubes, complete with their stators, but I don't know how to wire. Been trying to look up diagrams, and I'm good with electrical work, just don't know the correct voltages. Trying to make it for display and don't want to burn the filaments out on my tubes, and getting them to spin would be awesome. Tried straight ac once but didn't work. Not sure how the (and what specific kind) of capacitor it needs to start. I know the filaments are ac also, but would a dimmer switch work or enough voltage from DC?
@RateReducer

Hi. I used a adjustable DC power supply on the filaments. I don't know the proper voltage or amperage of the filament so i just increased the voltage until the filament(s) light up. It does not matter if use DC or AC on the filaments... I used coils of old contactors as a improvised stator winding. One coil on AC and the other coil also on AC but with a capacitor in series. The cap generates a phase delay and so there is a rotary field created by the two coils. Your stator supply should be a 110V or 230V type. Try a cap in the 10µF range. When you have a variac - use it.

The larger the spot size the lower the resolution. It directly affects the resolution of any image you take, think of it like that, a small light source casts clear shadows while a larger one casts very diffuse shadows. But the smaller filament won't boil off as many electrons so you have to do longer exposures or generally use less dose.

My question was is the motor or the coil is which rotates the anode inside the xray tube is that coil or motor fixed inside the xray tube or they are separate part? As I came to know from a xray tube seller he tells both are separate part, there is no motor or coil inside the xray tube. Maybe the coil or motor can be inside the shield housing of the xray tube, but not inside the xray tube.

@@muhaiminchoudhury2866 looks like motor core is inside tube and exciting coils are outside. So either induction motor or perhaps permanent magnet rotor.
Well done. Thank you. Rotate anode to prevent hot spots?

The energy is turned into 99% heat and 1% x rays
What is the function of the filament?

It emits electrons
Cooolllll.
also,... is it safe to stand so close while it is operating?

thaumas ein it needs about 125kV to produce xrays... I only run the filaments and turn the anode.
I have a query -what safety measures are you taking while operating the X-ray tube

None because I don't run it. There is no high voltage applied.
Cool and for what the utility?
You didn’t even fire up the tube, you just turned on the heating filament

Yes, because it would not work outside of it's oil filled container. There would be a instant high voltage short circuit. I just explain how the tube works.

@@RateReducer Nice! I didn‘t want to seem rude. I just wanted to know how it looks when one pole is rotating. However ,my curiosity is in no way important compared to your safety and health. Please be careful with these things and have a nice day.
how many watts will it consume if you run it for 10 minutes?
Do you know the Type No./Manufacturer of the tube? Also, at which voltage did you drive the filaments? Asking cause I might have the same tube, here. Greetings

It's a Philips tube. 125kV. I think I used about 5V on the filament. MFK - Daniel ;)
how on earth were you not exposed to xrays?
