Determination of the Electron Energy Distribution Function of a Low Temperature Plasma from Optical Emission Spectroscopy

The experimental determination of the electron energy distribution of a low pressure glow discharge in neon from emission spectroscopic data has been demonstrated. The method extends an approach by Fischer and Dose. The spectral data were obtained with a simple overview spectrometer and analyzed using a strict probabilistic, Bayesian data analysis. It is this Integrated Data Analysis (IDA) approach, which allows the significant extraction of non-thermal properties of the electron energy distribution function (EEDF). The results bear potential as a non-invasive alternative to probe measurements. This allows the investigation of spatially inhomogeneous plasmas (gradient length smaller than typical probe sheath dimensions) and plasmas with reactive constituents. The diagnostic of reactive plasmas is an important practical application, needed e.g. for the monitoring and control of process plasmas. Moreover, the experimental validation of probe theories for magnetized plasmas as a long-standing topic in plasma diagnostics could be addressed by the spectroscopic method. pdf

Analysis of the data quality of the H1 Fast Track Trigger
In order to take most advantage from the HERA II luminosity upgrade, the trigger system of the H1 detector is being improved. Besides other measures this includes the implementation of a new fast track trigger (FTT) that uses information of the central drift chambers of H1. The aim of this work was to help during the commissioning of the FTT and to provide some tools for the analysis of the monitoring data of the FTT system. A graphical display for the FTT front end was written. Tools measuring the hit finding efficiency with various methods were implemented. The drift information of the FTT hits were calibrated taking into account a T0 offset determined per wire, the chamber alignment and variations of the drift velocity and Lorentz angle. The effective wire lengths and z shifts needed for the determination of the z coordinate by charge division are measured in a second calibration procedure. H1 thesis 390, pdf
