- UMIST linear system
The ULS (UMIST Linear System) is a gas target
divertor simulator located in the formerUMIST campus of theUniversity of Manchester . It enables physicists to study therecombination processes of a detached plasma in ahydrogen target chamber.Research on detached plasma and on its recombination modes is of primary importance in order to design an appropriate divertor region in a future
nuclear fusion power plant, where huge amounts ofenergy will be deposited by the fast moving particles generated in the mainreactor . The major goal of the ULS as for many other linear divertor simulators, is to reproduce the sametemperature anddensity conditions of the SOL (Scrape Off Layer ) of atokamak in a linear envirolment and therefore to make easier the study of its properties.In the past few years, ULS has been used with great insight to analize the molecular actived and the electron-ion recombination modes, and to determine the conditions for their activation. Diffusive processes have also been considered. However, research on these subjects is still ongoing and, at the present time, our understanding of the elementary processes involved in a
detached plasma is still far from being satisfactory.
