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.

Methods 15, 697–699 (2018)]. A key figure of single-molecule EPR is that it can resolve heterogeneous molecular information, which is averaged in conventional EPR measurement. However, the current single-molecule measurements are insufficient to do so, due to the poor spectral resolution. Here, I will introduce an easy way to substantially improve the spectral resolution, i.e., removing the magnetic field. The zero-field EPR has been well-studied for decades [Chem. Rev. 83, 49–82 (1983)]. It has narrower spectra with the tradeoff of much poorer sensitivity. Difference from conventional inductive detection, the signal of NV-EPR comes from the statistical fluctuation rather than the thermal polarization of spins, which does not depend on the magnetic field. Therefore, the NV center is an ideal sensor for zero-field EPR detection. I will show that the NV-EPR has the advantage in not only spatial resolution but also spectral resolution.Biography of Dr. Fei KongDr. Fei Kong was born in Hefei, China. In 2012 he obtained a B.Sc. degree at the University of Science and Technology of China (USTC) and later undertook experimental research there on control and simulation using nitrogen-vacancy centers in diamond with Prof. Dr. Jiangfeng Du and Prof. Dr. Fazhan Shi. He received a Ph.D. degree based on this work in 2018. After 3 years of postdoctoral research on t...

Images are ubiquitous in our lives and are a fundamental and indispensable medium for the dissemination of information. Imaging is a direct means of acquiring images and can be classified according to the different imaging wavelengths as visible, radar, infrared, and terahertz imaging. With the further development of information technology, new demands are being placed on spatial resolution, signal-to-noise ratio, multispectral imaging performance, and the imaging environment.  Single-pixel Imaging Technology   With the increase in computer arithmetic power and the development of compressed perception theory, scientists have proposed a single-pixel imaging technique based on a computational imaging approach. This is a new imaging method that uses a single-pixel detector without spatial resolution and a spatial light modulator to obtain images by reconstruction. Compared with the traditional array detector imaging method, single-pixel imaging has the advantages of high sensitivity and interference resistance and has obvious advantages in the fields of very weak light imaging, non-local imaging, special band detection without large surface array detectors, etc. It has very broad application prospects in many fields such as nuclear magnetic resonance, aerospace remote sensing, and terahertz imaging.   Advantages of Single-pixel Imaging  Image Credits: High throughput dual-wavelength temperature distribution imaging via compressive imaging.Opt. Comm. 410, 287-291 (2018)   Single Pixel Photon Imaging Teaching Instrument   Although computational imaging, represented by single-pixel photon imaging, is promising, there is still a lack of experimental teaching content at the undergraduate level. In order to improve the relevant curriculum and help students develop their scientific research skills, CIQTEK, in collaboration with Professor Qing Zhao's team from the Technology Research Centre of Beijing University of Technology, has created a single-pixel photon imaging teaching instrument.   The product is a teaching instrument based on the theory of compressed perception and photon counting imaging technology, using digital micromirror devices to accomplish rapid imaging of random spatial light-modulated target objects. The product takes advantage of the sparse signal characteristics of the compressed sensing technique to go beyond the traditional Shannon sampling theorem and can restore images with high spatial resolution and high signal-to-noise ratio in very low light conditions with fewer measurements.   CIQTEK Launched Single Pixel Photon Imaging Teaching Instrument   The single-pixel photon imaging teaching instrument has a wealth of hardware modules to support students' hands-on adjustment and construction, facilitating students' understanding of spatial light modulation techniques and equipment usage, understanding the principle of compressed perception and imaging methods, and knowing the characteri...
