Enhanced small scale turbulence oscillations correlated to sawtooth relaxations in the textor tokamak
[Juel-2025]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2025, 19 p., Anh. (1985)
A periodic enhancement of the microturbulence level by sawtooth relaxations has been detected by CO$_{2}$ laser forward scattering in the TEXTOR tokamak. This feature is reproduced quantitatively by a heat transport code in which the anomalous electron transport coefficient is calculated self consistently following a theoretical model of the saturation of the dissipative trapped electron instability.

Untersuchungen zum Adsorptions- Desorptionsverhalten von CO auf der Pt(111)-Oberfläche mit der Molekularstrahlrelaxationsspektroskopie und der Streuung thermischer Heliumatome
[Juel-2022]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2022, VI, 117 p. (1985)
Adsorption and desorption of CO on a defect-free Pt(111) surface in the low coverage limit is studied with Molecular Beam Relaxation Spectroscopy (MBRS) and Thermal Energy Atom Scattering (TEAS). A new apparatus was built up for this purpose. [...]

Relativistische Theorie der Photoemission und Streuung langsamer Elektronen von ferromagnetischen Oberflächen
[Juel-2021]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2021, VIII, 157 p. (1985)
A relativistic multiple scattering theory (layer-KKR-formalism) for ferromagnets is formulated. Therefrom methods are derived to calculate bulk bandstructure andscattering and photoemission of low energy electrons from surfaces. [...]

Experimente zur lichtinduzierten Ca$^{2+}$-Freisetzung aus Diskmembranen von Rinderretinen
[Juel-2020]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2020, III, 107 p. (1985)
Light causes a transient permeability increase for Ca$^{2+}$ in bovine rod outer segment disc vesicles. The calcium release from these vesicles can be measured spectrophotometrically at 652 nm using the metallochromic indicator Arsenazo III. [...]

Untersuchung der Desorption und Permeation von $_{2}$ an Cu-beschichteten Pd Einkristallen
[Juel-2017]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2017, II, 71 p. (1985)
The velocity distribution of D$_{2}$ desorbing from the Pd(111) surface as a function of Cu coverage was investigated by time-of-flight measurements. Starting with the clean Pd surface, when a Maxwellian distribution corresponding to the surface temperature (T$_{s}$ = 360 K) is observed, the mean energy of D$_{2}$ increases with Cu coverage. [...]

Real time evaluation of electron and current density profile parameters on Textor
[Juel-2016]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2016, 14 p., Anh. (1985)
The shapes of electron and current density profiles are monitored in real-time mode in order to get rapid qualitative information on the development of a TEXTOR tokamak plasma. The profiles are described by form parameters which relate to the signals of a 9-channel FIR-polari/interferometer in simple mathematical formulae. [...]

[Juel-2015]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2015, 148 p. (1985)
Spin density functional theory and the KKR-Green's function method are used to calculate selfconsistently the electronic structure for magnetic 3d-impurities and magnetic 3d-impurity pairs in Cu, Ag and Pd. We calculate the local densities of states and the local moments for the magnetic impurities and for the ferro- andantiferromagnetic pair configurations. [...]

Biokinetik Tc99m-markierter RES-Kolloide im Menschen
[Juel-2014]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2014, 82 p. (1985)
The pictorial representation of the liver and spleen by scintigraphic methods is based on radioactive labeling of the RES cells of these organs by Tc-99m colloids, which are largely cleared from the blood by the RES cells following intravenous injection. Estimates of the radiation dose resulting from liver scans are based essentially on biokinetic data derived from animal studies. [...]

[Juel-2012]
Jülich : Kernforschungsanlage Jülich, Verlag, Berichte der Kernforschungsanlage Jülich, 2012, 112 p. (1985)
Helium has been introduced into 100 $\mu$m thick pure Cu specimens by implantation of $\alpha$-particles at T = 300 K. Post-implantation annealing of the specimens at high temperatures caused helium to precipitate into bubbles. [...]
