FREIA - Facility for Research Instrumentation and Accelerator Development
Uppsala University is constructing at its Ångström Laboratory a large scale facility, called FREIA, for research and development of new accelerators and instrumentation for accelerator based research. FREIA will be build-up in stages, starting with a radio-frequency (RF) development facility and a cryogenic facility. FREIA will be housed in a new 1000 m2 experiment hall next to house 7.
The cryogenic facility will produce and distribute liquid helium and liquid nitrogen for research at the university. In addition it will provide test cryostats for experiments. This facility is supported by a grant from the Knut and Alice Wallenberg stiftelsen. It is the key infrastructure required for developing the superconducting accelerating technology required for future free electron lasers and high intensity proton accelerators.
The RF facility is intended for research and development of RF power generation, distribution and control for superconducting and normal conducting accelerating cavities for future accelerators.
In a first project, Uppsala University, in collaboration with ESS AB, University will develop the technical systems to generate and control the 5 megawatt RF power that is needed for the 450 meter long linear proton accelerator to be by the European Spallation Source (ESS) in Lund to generate its neutron flux.
With support from ESS AB, FREIA will be used to develop and test a 352 MHz 350 kW peak power RF system. The system will be tested with ESS prototype spoke resonators.
FREIA is also planning to construct a 12 GHz klystron-based test stand for the development of CLIC type compact very high gradient accelerating structures.
