The injection into a separated sector cyclotron (SSC) aimed at the production of a high power 800MeV/amu molecular H2+ beam for ADS-Reactor applications * is being designed. This work includes the definition of the parameters of the injection line, as well as beam dynamics simulations of the line and first accelerated turns using the OPERA magnetic field maps of the cyclotron sector. Both schemes of radial and vertical injection are assessed. Various optics codes are employed for that as MADX, Zgoubi. The paper details and discusses various aspects of that design study and its outcomes.

A future electron ion collider "QCD test facility" is designed in the present Relativistic Heavy Ion Collider (RHIC) tunnel. Electron acceleration and de-acceleration is preformed with energy recovery linac with multiple passes. We report on a combination of a multi-pass linac with the Non-Scaling Fixed Field Alternating Gradient (NS-FFAG) arcs. A single NS-FFAG arc allow electrons to pass through the same structure with an energy range between 1.425 and 10 GeV. The NS-FFAG is placed in the existing RHIC tunnel. The 200 MeV injector bring the polarized electrons to the 1.225 GeV GeV superconducting linac. After one pass through the linac 1.425 GeV electrons enter NS-FFAG arc and after 7 passes reach the energy of 10 GeV. After collisions the beam is brought back by the NS-FFAG and decelerated to the initial energy and directed to the dump.
