  Presently in Europe the first generation of particle-therapy accelerators is on the way from construction into operation. Each layout typically consists of two ion sources, a single injection line, a main synchrotron and beam transfer lines to several treatment rooms, one of them equipped with or foreseen for an ion gantry. The paper presents some possible enhancements for the next facility generation still based on existing layouts and design studies. The focus lies on an improved injection line and gantry concepts. A simplified injection line using a different configuration of ion sources and low-energy beam-transport line is described. It is based on combination of particle species with identical charge-to-mass ratio. Optimized gantry constructions are shown with mechanical designs driven by ion-optical demands, especially by the accuracy of the beam position at the isocentre. The enhancements presented in the paper may influence upgrades of existing centres or may be implemented in the design of newly developed next generation of particle- therapy accelerators.
