hmm so basically,

 

if the accelerator is lighter than the

mass of the particles being accelerated,

it may benefit from the propulsion.

 

and the mechanism of this may not

require as much material volume

as would a particle collider.

 

the particles need not be guided,

but singular way out in propulsion.

 

but. those particles are limited

by quantity so if to be recycling this.

 

guided by electromagnetism.

to be re-inserted into the accelerator.

 

 

sci-fi.

 

but who knows.
