Talk:Relativistic electron beam

I canged the tempus in the use of REBs in PEARL as the text referenced to seem to propose such a facility rather then descibing an existing one. That text does mention the existance of free electron lasers (FELs), so I added a link to that article (they seem intriguing and exotic ;). I also added a link to Relativistic particle.
