Fig. 1From: RF deflecting cavity for fast radioactive ion beamsTop: Stages of beam purification. I – Fragments have different velocities. II – Due to the velocity difference, the distance between fragments increases, and they interact with a different electric field of the RF fragment separator. III – tail particles are deflected and stopped by a slit. IV – the beam is purified from the fragments. Bottom: RF fragment separator concept [15]Back to article page
