Overall ring length about 6Km,Collision frequency about 120Hz*10000bunch_trains=1.200MHzBunch train stays in the rings for 8.3msec, then is extracted, compressed and focused. After the collision the bunch is reinjected in its ring

Why not make a fresh beam if storage time is greater than 1 damping time
