Antimatter and Relativity

If you were to take an antimatter reactor and set it going somwere at relatavistic speed, (preferably orbiting a fixed point, difficult though this would be) and design it to coherently radiate (as in a laser) power. Do you get relativistically increased output?

I think you would get a decreased output instead of an increased one. Since time will appear to be goin slower aboard the source than the target the laser would have a lower relative output per unit time, a lower intensity.

damm. forget it then. I was thinking of completely the wrong thing. Now I think about that fully rested the mass increase is matched by the time dialation. Conservation of Enegy slaps me in the face once again.

As demonstrated by one of the earliest proofs of time dilation - subatomic particles in colliders living longer than they should. They were travelling so fast in the detector that their half life (to them) was right, but to an external observer was as much longer as time dilation said it should be.

Heres a question, when an object is moving, is its total energy more then then just its potential annihilative energy, or is that annihilative energy transfered into mass and increases the effects of the particle?

For instance, would a relativistic antimatter beam do more damage then a non relativistic particle beam, or would the effects be equal because the energy of any relativistic mass is almost equally to the energy equivalent??
