In this talk I will give an overview of my work on ultra-thin magnetic films (<1 nm) and hope to convey my excitement of the incredibly rich physics playground it offers. For instance; the recent observation that relativistic effects, initially considered useless/undetectable, have huge (unexpected) impact on magnetic nanotechnology.
There is strong cosmological and astrophysical evidence that more than 85% of the matter in the Universe is composed of non-luminous --dark-- matter, which is fundamentally different from ordinary matter. Of the many candidate particles, Weakly Interacting Massive Particles (WIMPs), arising in extensions to the Standard Model, are particularly well-motivated. One method to detect WIMPs is to measure the nuclear recoils produced in their rare elastic collisions with ordinary matter.
For DEMO liquid metal plasma facing components are considered due to their resilience to erosion through flowed replacement, potential for cooling beyond conduction and inherent immunity to many of the issues of neutron loading compared to solid materials. The development curve of liquid metals is behind that of e.g. tungsten however and tokamak-based research is currently somewhat limited in scope. Therefore investigation in linear plasma devices can provide faster progress under controlled and well-diagnosed conditions in assessing many of the issues surrounding the use of liquid metals.
abstract will soon follow
Main processes of plasma-wall interaction and impurity transport in fusion devices and their impact on the availability of the devices are discussed. According modelling tools, in particular the three-dimensional Monte-Carlo code ERO, are introduced.
