Anyone have a solid piece of pure tungsten (98% pure or better) they might

x-ray tubes use tungsten for the electrode/target. Nearly always round,
as the modern ones spin. I know that GE Medical Systems scraps out the
field returns, because a friend of mine runs the operation.

If the anode looks like something you'd be able to work with let me
know, I can see if they can sell the parts to individuals rather than
for scrap.
