The Institute for Particle and Nuclear Physics (RMI) conducted basic research in experimental and theoretical physics including particle physics, nuclear physics, plasma physics, the physics of cold atoms, space physics, nuclear solid state physics, nuclear material science, and the biological applications of physics. The main fields of developments were: laser physics, nuclear analytics, fusion plasma diagnostics, space physics, fast data processing, spectroscopy, special instruments for electronics, and mechanics and information technology including software for various operating systems. It also improved and operated the EG-2R electrostatic accelerator, the NIK Heavy Ion Implanter facility, the MBE Molecular Beam Epitaxy device, the GRID computing system, and other high-power computer networks. It developed and operated the computer network of the KFKI Campus and served as the regional centre of the National Information and Infrastructure Development Program. RMI researchers developed and operated the computer network center.
