> bombarding lead with a beam of titanium-50 accelerated to 10% the speed of light

Please forgive the poor understanding, but isn't titanium non-magnetic? How does one accelerate titanium?

They are talking about titanium ions.

oh, right. Thank you for helping a bear with very little brain.

I've always wondered how this actually works. Do you have to vaporize it first? How do you actually get titanium to become free-floating (?) ions?

I believe it is vaporized then (partially) ionized by bombardment with electrons.
