Design of system for Transient EPR spectroscopy

Ing. Antonín Sojka

Institute of Physical Engineering


Transient EPR Paramagnetic Resonance Spectroscopy (EPR) is an EPR method by which photo-excitatory paramagnetic features as molecular multiple states or radicals can be investigated. The method provides kinetic information in a time of a few nanoseconds about relaxation photo excited states. The aim of this work is to design a sample holder for transient EPR spectroscopy and the implementation of laser radiation on the sample. It will be focused on subsequent implementation of trEPR into the already existing system of Terahertz High Speed Scanning Electron Paramagnetic Resonance Spectrometer (THz-FRaScan EPR). The main part of the thesis will deal with the introduction of optical fiber into the existing EPR concept and the subsequent testing of the whole assembly.

Upgrade of ESR spectrometer for observation of reactions in photosensitive materials

For development of new photosensitive materials and optimization of their processing is necessary to understand dynamics of radical reactions during exposition. To observe these reactions by ESR spectrometer, the spectrometer must be upgraded, so sample can be exposed to UV light.

Implementation of a DSP algorithms in FPGA for ESR spectroscopy

FPGAs presents flexible option for a high-speed data processing. This can be useful in many specific experimental measurements.
