The symposium this year is an online event for international speakers and participants, a new start for Asia-Pacific EPR/ESR Society in the post-epidemic era. The main aims of APES 2022 are to bring together EPR/ESR spectroscopists and to promote and facilitate collaboration among the EPR/ESR community. APES 2022 is intended to stimulate discussions on the forefront of research in all aspects of EPR/ESR ranging from theoretical and experimental advances in CW/Pulsed EPR, high frequency, and high field EPR, ENDOR, PEDLOR/DEER, time-resolved EPR, FMR, MRI, ODMR to applications in medicine, biology, chemistry, materials science and nanotechnology. On November 6, Dr. Sergey Veber gave a presentation entitled "X-band EPR spectrometer based on MW bridge with 300 W solid-state amplifier and AWG unit". Abstract of the PresentationTechnical advances in modern EPR spectrometers set up the frontiers of EPR-related methodologies and approaches. Considering EPR spectrometers of conventional microwave bands, such as X- and Q-, high-power amplifiers, arbitrary wave generators, and fast digitizers are the essential units required for up-to-date pulse EPR techniques.Herein we describe an X-band EPR spectrometer constructed in the Magnetic Resonance Laboratory of Biomolecular Systems (NIOCH SB RAS) and featuring all the required equipment to perform state-of-art pulse EPR experiments. Among the general construction of the spectrometer, the scheme of the microwave bridge is considered in detail including a pulse-forming and pulse-monitoring unit, and a low-noise amplifier with a pulse protection circuit. A modular open-source software "Atomize" (https://github.com/Anatoly1010/Atomize) is used to control the spectrometer including AWG and fast digitizer cards featuring high-speed data streaming. A wideband dielectric EPR resonator was developed to fit the requirements for AWG experiments with chirp pulses. The spectrometer is designed to have a high dynamic range, low coherent noise and to capture the direct dimension efficiently. These capabilities were demonstrated with both rectangular and AWG pulse experiments.
