Development of a control system for pulsed-electron spin resonance spectrometers.
A pulse control and data acquisition system with high time resolution of 300 ps and data-averaging rate of 100 kHz for a pulsed-ESR spectrometer was constructed. The system consists of two sets of 3.34 GHz data timing generator and a dual-channel analog-to-digital converter with 1 GHz samples, both of which are commercially available. We developed a scheme and software to control these equipments with high efficiency in pulsing design, data acquisition, and accurate synchronization of the devices. The system was developed at Ku band (17.5 GHz) and demonstrated some examples of electron spin echo and double quantum measurements.
