Eric Rassmussen sent me an e-mail in the 2001 season telling us we couldn't use dilithium (element 119) on our robot, since it would be too difficult to acquire for most teams.
Trying to control a matter-antimatter reaction with magnetic fields only, without dilithium, would be pointless even if the team could produce suitable anti particles from small parts material.
They could, however, produce a bit of positron radiation from normal matter that displays radioactivity through positron decay. Perhaps they planned to isolate such an isotope from small parts stock metal.
