I have a surplus xray dental head that I would like to reuse.
It has four wires entering it.
What is in a head like this and how can one use it for xraying items?
Any links to sites that describe how this device is constructed would
be appreciated.
Thanks

Thanks for quick response...it is appreciated.
The only information on the head is ...
"XRM"
"an S.S.White subsidiary"
and just inside the head is the writing....
"1178G-1228"
The four wires (all different colors) are not HV wires (normal
insulation thickness) and they attach to what looks like either diodes
or pass through studs.
From the looks within the head, I suspect that it is filled with
oil...likely for heat transfer and perhaps dielectric insulation for
the HV within the head. I see a number of copper fittings which again
would indicate effort is being made to quickly transfer heat out from
the head.
I did not want to go further with disassembly until I did some
research on what is behind the next cover.
I *suspect* that there is a voltage multiplier contained within that
supplies the needed HV for the tube.
So...does four wires entering the head by the "diode/stud" connections
indicate a possible HV multiplier?

The head that I am working with looks like this one....

Certainly looks like there is more in there than the tube. At the very
least, the multiplier, but possibly the entire HV inverter.
You might try contacting an X-ray equipment supplier, though I bet
they will claim liability issues in providing any info.
