Microwave spectrometer for Rydberg state atoms: Last improvements

Abstract

The results of essential improvement of the microwave spectrometer for investigation of spectra of Rydberg state atoms are presented. The spectrometer was equipped by a new time domain (waveform) acquisition system, which allowed us to apply time selection of useful signal. Such solution significantly improved signal-to-noise ratio of recorded spectra. The result of test measurement of a microwave transition between Rydberg states of magnesium atom is presented.
