ATOMKI operates the major particle accelerator in Hungary. The MGC-20 cyclotron has been delivering accelerated particle beams for both basic and applied research, medical and industrial applications as well since the end of 1985. The cyclotron can accelerate particle beams from proton to alpha with variable energies and in a broad intensity range. Using its sophisticated external beam transport system equipped with advanced beam diagnostics and instrumentation, it can be flexibly adapted to the diverse requirements of different research and application projects, making it a real multidisciplinary research tool.

The only Hungarian Electron Cyclotron Resonance (ECR) Ion Source (ECRIS) is operated at Atomki. As a member of the Atomki Particle Accelerator Centre, ECRIS provides plasma and ion beams as a stand-alone low-energy accelerator.

Main fields of activities:

• fundamental research (astrochemistry, atomic physics, plasma physics) and
• some applications (surface physics, medical implants).

• Proton     energy: 200 keV - 4 MeV,     current: up to 200 eµA,     brightness: 8-16 Amp(rad)^-2m^-2eV^-1
• Helium     energy: 200 keV - 6 MeV,     current: up to 40 eµA
• Other ions: e.g. B, C, O, S, Si, Cu etc.     energy: 200 keV ~ 10 MeV (depending on charge state),     current: up to 10-50 eµA (depending on ion species)
• Terminal voltage stability: ± 30 V / 4 hrs (slits stabilization)
• Terminal voltage ripple: 25 V_RMS
