Description
JULE-PSI is a linear plasma device to investigate the response of neutron pre-damaged materials (including toxic materials such as beryllium) to steady – state plasma loads and transient heat loads provided by laser irradiation. JULE-PSI will be equipped with a target analysis and exchange chamber to characterize the material surface in-vacuo and will be located inside of a Hot Cell to allow for handling of activated target samples.
In this contribution, we will first review the scientific case for investigations of neutron damaged materials in view of plasma –surface interactions, discussion the impact of synergistic loading conditions onto the lifetime of plasma facing components and the influence of neutron damage on fuel retention.
Then, we will give a status report of the JULE-PSI project, describing the design of the plasma device and its components (plasma source, magnets, pumping system and vacuum vessel) as well as the set-up of the New Hot Cell in the High Temperature Material Laboratory of Forschungszentrum Juelich (HML), which has recently been evaluated by an external company. Currently, JULE-PSI is under construction outside of the controlled area and will be moved to HML early 2018 according to the present schedule.
