Bayesian Consideration of the Tomography Problem
Soft X-ray tomography has become a standard diagnostic equipment to investigate plasma profiles. Due to limitations in viewing-access and detector numbers the reconstruction of the two-dimensional emissivity p...

Magnetic phase transitions and correlation effects in two-particle spectroscopies
We discuss the manifestation of magnetic phase transitions of 3d-transition metal or 4f-rare earth materials in two-particle spectroscopies such as Auger-electron (AES) and appearance-potential spectroscopy (APS)...

Influence of surface roughness and chemisorption on magnetic hysteresis curves of a Ni(110) surface observed by spin-resolved inverse photoemission
Using the high spin asymmetry in inverse photoemission of the Ni d-band just above the Fermi level as an indicator of surface magnetization, we have measured hysteresis curves of the (110) surface of nickel. Near...

SIMS analysis of isolated graphite probes exposed to a tokamak plasma
Probes made of graphite were exposed to deuterium plasma of the tokamak discharges. The probes were highly polished and annealed in vacuum to about 900 ° C previously. They were kept isolated from the wall. Ea...

Electron Emission from Solid Surfaces
Electrons are emitted from solid surfaces as a result of heating, of ion, electron and photon bombardment from the plasma, and if a sufficiently high electric field is applied. Thermal electron emission only b...
