A CRT or cathode ray tube is a very small particle accelorator. It is used in old TV sets that used a "tube" and older computer monitors.
The projection TV sets used a larger and higher powered one. I remember my brother-in-law trying to get rid of his old malfunctioning projection TV set and tearing it apart with a hammer and crowbar to make it fit in a dumpster. They had three cathod ray devices one green, one blue, and one red. Eacn one had 'warning radiation hazard' on them and the only protection the TV viewer had was this wooden posterboard material and no metals or lead at all.
It is said that using these CRTs in a way with an aluminim scoop as a cyclotron you can turn some basic metals and materials into a weapons grade material for use in a dirty bomb or possible turn it into something in the lanthaium series, which could make an atomic bomb or something.
It is said that the Manhattan Project was low buget like $500 Milion or something to refine the urianium or plutinium or whatever they had into weapons grade, and that at that time the tech was ahead of its time, but it is used in ordandary stuff and 1970's technology and can easily be converted.
That the real reason to go to digital TV sets was to get rid of all of the CRTs that could have been used to make weaponized materials. LCD and Plasma screens work on a different principle.
I'd imagine someone of Crawford's genuis would take a CRT and turn it into a man portable particle accelorator gun and start zapping some terrorists or something.
