| Outline of Final Research Achievements |
The goal of the present work was developing a digital electron spin resonance (EPR) spectrometer aiming at high sensitivity and low cost. We succeeded in acquiring magnetic resonance signal by continuous wave EPR method by fabricating an FPGA receiver board that can acquire high frequency signal of L-band without frequency conversion. In addition, we proposed a new digital automatic suppression control method of reflected wave, and verified it using the signal-processing algorithm implemented on the FPGA. As a result, we successfully developed a digital EPR spectrometer that can operate stably to acquire EPR signals from living animals.
