I et samarbeid mellom Universitetet i Oslo (UiO) og det internasjonale forskningsanlegget European Spallation Source (ESS) i Sverige har det blitt utviklet en risikostyringsmetode for å sikre at partikkelakseleratoren og targetsystemet i ESS oppfyller kravene til både maskinbeskyttelse og tilgjengelighet. Arbeided vil bli presentert 3. november i form av en doktorgradsdisputas ved UiO. Arbeidet er et av de første samarbeidene mellom UiO og ESS, og markerer et nytt skritt for norsk akseleratorforskning.
For the past three years, a collaboration between UiO and ESS has developed a unique risk management method for the purposes of protecting complex systems and machines, such as research facilities and particle accelerators. The outcome culminates in a PhD thesis that is presented on November 3rd at UiO.
The thesis combines its findings into a so-called machine protection system of systems, where all of the relevant equipment in the facility is used to achieve the level of protection and reliability necessary for a research facility – in this specific case for the European collaboration ESS, which is built in Lund, Sweden. The method implements a set of additional functions into the research facility, which have the purpose of identifying problematic situations and take automatic actions when necessary.
The ability of particle accelerators to enable the study of tiny objects, such as the structures of atoms and molecules, makes them critical in the science of today and the future. In order to allow modern scientists to carry out their desired experiments, these particle accelerators need to be increasingly more powerful. But the power alone does not achieve the results – one also has to ensure that the scientific facilities reach a high reliability, so that experiments can run as planned. Modern equipment yields a high reliability in itself, but it is also important to have the proper risk management process in place to handle the many problems that can occur in such a facility. With the development of technology, also the methods used to implement and analyze this technology have to keep up. The method presented in this UiO thesis shows that it is possible to establish such a method in parallel with the design of the scientific facility. It is also a useful tool for future research facilities that need to consider reliability and scientific output.
