Originální abstrakt

A quasi-optic system is a common part of High Frequency Electron Paramagnetic Resonance (HFEPR) spectrometers. A main purpose for its use is to achieve low losses of a microwave signal1 in a wide range of frequencies, which is beneficial for a pulsed and a multi-frequency2 operation. However, a gaussian beam of microwaves has to be at some point transmitted into a probe-tube that is attached into superconducting magnet. A good coupling between the quasi-optic system and the probe-tube is therefore necessary. Usually, it is done by a tiresome manual adjustment of quasi-optic system into just right position, each time when a new sample is loaded, or the probe-tube is exchanged. To simplify this procedure, an automated alignment system was embedded into a newly constructed HFEPR spectrometer. It consists of five high precision servo drive mechanisms to allow three -dimensional position adjustment along an elevation adjustment of a whole quasi-optical table. The positioning system is controlled by a computer software that will do the tiresome adjustment procedure instead of operator
