Design of a Non-Resonant General Purpose Sample Holder for Terahertz Electron Paramagnetic Resonance Spectroscopy
Martínek, Tomáš ; Sojka, Zbigniew (oponent) ; Neugebauer, Petr (vedoucí práce)
The aim of this diploma thesis is to design dedicated sample holders for a high-frequency electron paramagnetic resonance spectroscopy. The main task deals with the development of a user-friendly and fast locking system for connection between microwave waveguide and a sample holder. Two types of sample holders are designed one for loading multiple samples and one for single crystal rotation. Thanks to loading up to 6 samples the overall measurement time is estimated to be reduced more than twice. In the case of the single crystal rotator based on the precise piezoelectric rotator with resistive encoder a milliradian, precision is provided. Both sample holders are designed in such a way that the full automatization can be applied in the measurement.
