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 MGC-20 cyclotron of ATOMKI has been the major particle accelerator facility in Hungary since it started operation in 1985. It is a variable energy compact machine which can accelerate particle beams from proton to alpha. For about two decades it was the only cyclotron type accelerator in the country and was used for various research and application programs. In recent years several new dedicated PET-isotope (Positron Emission Tomography) cyclotrons were put into operation in Hungary with comparable proton and deuteron final beam energies. Although these new machines are superior in beam intensity and economics of operation, the MGC-20 cyclotron is still the most flexible accelerator facility for research and non-routine application tasks. Its sophisticated external beam transport system with advanced beam diagnostics and instrumentation, combined with the broad range of variable beam parameters makes it a unique tool for numerous programs.
