“…We will not take into consideration special devices developed for astronomy or advanced projects, whose price is currently at least an order of magnitude higher than that of our CCDs. Thus we will make no specific references to the vast literature on X-ray CCDs [15][16][17][18][19][20][21], because our point of view is that of users interested in the optimal use of CCD detectors in the field of soft X-ray spectroscopy at the synchrotron radiation facilities. We are not going to discuss the physics and the technology of CCD devices per se.…”

“…CONCLUSIONS Due to its low cost and broad functional capabilities, the detector under development can be used efficiently in physical experiments that require recording of radia tion intensity distribution with high spatial and time resolution. Moreover, the detector can be adapted for fast recording of extremely weak images if the TC237 is (2) SR beam from an unperturbed orbit absorbed by a gap; (3,4) perturbed electron trajectory; (5) SR beam after perturbation; (6) X ray collimator; (7) collimated SR beam (duration ~1 ns); (8) studied sample with shock (detonation) wave (9) containing crystalline particles (10) (resulting in diffraction); (11) CCD sensor in the imaging spectrometer mode; (12) set of recorded events (from single hitting X ray photons); (13) scattering pattern of the white beam reduced to (14) scattering pattern of monochro matic radiation.…”

A detector for fast diagnostics of particle beams in storage rings using an optical component of synchrotron radiation (SR) is developed. The detector records a limited series of one dimensional or small two dimensional images at a rate of (1-10) × 10 6 frames/s. It can also be used for investigating fast processes in X ray SR beams. In particular, matched with a structured scintillation screen (with low deexcitation time), this detector provides a recording with an SR flash rate of shadowgraph images (for axially symmetric objects, initial data for tomograms) or a record of the distribution of small angle X ray scattering. It is also possible to apply this detector as a dispersion free image spectrometer; this would make it possible to perform pulsed X ray diffraction studies with "white" SR beams. In the single flash mode this would provide a record of the for mation and behavior of crystalline phases in shock and detonation waves with a time resolution of up to 1 ns.

“…Spectroscopy is utilized in various research fields such as physics, chemistry, agriculture, and medical science, and delivers valuable insights and knowledge. Spectroscopic data based on light, X-ray and electrons is often obtained using charge coupled device (CCD) detectors [1][2][3][4] , and their resolution is sometimes limited by the number of pixel arrays in the CCD detectors. In Raman spectroscopy, for example, peak positions are slightly shifted depending on the temperature, carrier concentration and strain in semiconductors and low-dimensional materials [5][6][7][8][9][10][11][12][13][14] .…”

The resolution of spectroscopy, which delivers valuable insights and knowledge in various research fields, has sometimes been limited by the number of multi-channel detectors employed. For example, in Raman spectroscopy using charge coupled device (CCD) detectors, the resolution is limited by the number of the CCD arrays and it is difficult to achieve spectroscopic data acquisition with high resolution over a wide range. Here we describe a methodology to increase the resolution as well as signal-to-noise (S/N) ratio by applying Bayesian super-resolution in the analysis of spectroscopic data. In our present method, first the hyperparameters for the Bayesian super-resolution are determined by a virtual experiment imitating actual experimental data, and the precision of the super-resolution reconstruction is confirmed by the calculation of errors from the ideal values. For validation of the super-resolution of spectroscopic data, we applied this method to the analysis of Raman spectra. From 200 Raman spectra of a reference Si substrate with a resolution of about 0.8 cm-1, super-resolution reconstruction with resolution of 0.01 cm-1 was successfully achieved with the promised precision. From the super-resolution spectrum, the Raman scattering peak of the reference Si substrate was estimated as 520.55 (+ 0.12, -0.09) cm-1, which is comparable to the precisely determined value from previous works. The present methodology can be applied to various kinds of spectroscopic analysis, leading to increased precision in the analysis of spectroscopic data and the ability to detect slight differences in spectral peak positions and shapes.
