Název v původním jazyce

Automation of a Terahertz Frequency Rapid Scan ESR Spectrometer

Popis výsledku v původním jazyce

A high effort is currently invested in development of pulsed high frequency/field electron spin resonance (HFESR) spectrometers, which can satisfy a high spectral resolution and are suitable for spin-dynamics studies. However, their development has to overcome many challenges, mostly issued by generation, propagation and detection of terahertz waves. Our aim is to build a multifunctional broadband ESR spectrometer, based on a terahertz frequency rapid scan method (European Research Council Starting Grant THz-FRaScan-ESR), which maximum achievable magnetic field in cryostat chamber will be 16 T, and a frequency range of a terahertz source will between 80 and 1100 GHz. By the rapid sweep of terahertz wave frequency, the spectrometer will allow to acquire information about broadband ESR spectrum as well as relaxation time. A fast processing of acquired data is crucial, because a single scan can be done in a few microseconds and contain more than ten thousand points. For this reason, it is useful to do the most of a data preprocessing onboard by a field programmable gate array (FPGA). This will unburden a processor of operating computer, which can be used for other utilities as semi-automated evaluation of results or drawing of ESR spectrum
