This is important for the description of energy recovery linacs (ERLs) where bunches are recirculated at a decelerating... | physics-01.zip/physics_0405106.pdf |

The control system for all the ID's follows an uniform concept to allow a rapid installation schedule, while at the same time allowing for a variety in operational requirements. The components of the control system include the... | physics-01.zip/physics_0111208.pdf |

In the MuCF reaction process, muonic helium ions ($\mu$He$^+$) are created. By re-accelerating and stripping $\mu$He$^+$ ions, a low emittance negative muon beam is generated. | physics-01.zip/2211.02252.pdf |
