Paul Scherrer Institute (Switzerland)
The Paul Scherrer Institute (PSI) is a multi-disciplinary research centre for natural sciences and technology. In national and international collaboration with universities, other research institutes and industry, PSI is active in solid state physics, material science, particles physics, life sciences, nuclear and non-nuclear energy research, and energy related ecology.
The institute’s priorities comprise various areas of both basic and applied research, particular in fields which are relevant for sustainable development as well as for teaching and training, which are beyond the scope of a single university department. PSI develops and operates complex research installations, which call for especially high standards of know-how and experience, and is one of the world's leading user facilities for the national and international scientific community.
PSI operates a 590 MeV CW proton cyclotron with a beam current > 2 mA and the spallation neutron source SINQ receiving this beam. In 2006, the prototype liquid metal spallation target MEGAPIE using liquid lead-bismuth eutectic as target material replaced the standard solid lead SINQ-target, being the first MW-class liquid metal spallation target that was operated for a substantial period of time. Through the development, licensing, operation and dismantling of this target, PSI acquired world-wide unique knowledge in various areas related to the application of liquid metals in nuclear technology.
