Abstract Research at the Oslo Cyclotron Laboratory University of is focused on spectroscopy experiments for nuclear structure and astrophysics using Scintillator Array OSCAR. Light-ion beams from $$K=35$$ K=35 cyclotron are furthermore used studies in radia...

The concept of large-radius multistage coaxial cyclotrons having separated orbits is described , to generate proton beams of 120-2000 MeV energy at tens of GW pulsed and hundreds of MW in continuous beam power operation. Accelerated beam losses must be less than 0.1 W/m for the intercepted average beam power linear density. The concept is inherently configured to actively compensate the longitu...

Ion cyclotron resonance is one of the fundamental energy conversion processes through field-particle interaction in collisionless plasmas. However, key evidence for ion (i.e., coherence between electromagnetic fields and phase space density) resulting damping waves (ICWs) has not yet been directly observed. Investigating high-quality measurements plasmas by Magnetospheric Multiscale (MMS) satel...

This introductory paper contains personal perspectives about the importance of cyclotron resonance in forming our modern view of solids. The papers following this one will discuss the discovery, refinements, and some of the latest developments. Although I will touch on some of these subjects, I leave the details to the other authors and in the main focus on the conceptual impact of the work. I ...
