The passage around this formula

Electrons circulating in a storage ring undergo enormous proper acceleration — for an ultra-relativistic beam of Lorentz factor $\gamma$ on a ring of radius r , the proper centripetal acceleration is a $\approx$ $\gamma^2$ $c^2$ /r . For beam parameters typical of a large electron-positron collider, with $\gamma$ of order 2 $\times$ 10^5…
