If the acceleration is given by the centripetal acc, a = v^2 /r

then if synchrotrons have a bigger radius, does the acceleration then decrease?

or can v^2 not be kept constant?

I dont understand how bigger radius helps in the synchrotron, if anyone could kindly explain :s sorry...

thanks

Basically, when a charged particle is accelerated it emits radiation, which is inversely proportional to the radius of the circle, so the bigger the synchratron is, the less energy is lost due to radiation.

The synchrotron supplies energy using an electrical field, and keeps the particles going around in a circle using a magnetic field. Having a larger radius means that they just need a stronger magnetic force, and this doesn't place a limit on how much they can speed up the particles with an electrical field.
