“…For accurate calculation of flux with taking into account the focusing element and absorption in the beryllium windows, we used Shadow software. [ 3 ] According to the simulation results the photon flux on the sample for a window of 400 × 400 µm, in confirmation of the obtained values from the ionization chambers increased ≈3–4 times and amounted to

“…The number of photons formed by the synchrotron radiation source (radiation flux per 1 mrad in the orbit plane, integrated in the direction perpendicular to this plane) is determined by the following formula. [ 3 ]

N (λ) = 2.46 \cdot 10^{16} \cdot E \cdot I \cdot η (λ / λ_{c}) \cdot Δ λ / λ photons {normals}^{- 1}

where

η (λ / λ_{c})

is the universal spectral function, I is the current in the storage ring and

Δ λ / λ

is the spectral interval for monochromator crystals. The number of photons on the “Belok” beamline for 400 × 400 µm window was

N false(λ false) ≅ 1.7 \cdot 10^{11}

Introduction of "Belok/XSA" beamline-modernization is presented here with commissioning of a modern synchrotron beamline with unique capabilities for the structural analysis of single and polycrystalline samples. The beamline is designed to perform important tasks in modern crystallography, such as solving and refining the atomic structure using the single-and polycrystal method, studying the real (defective) structure, and analyzing the distribution of electron density in crystals, it is also possible to study rapidly occurring processes, for example, temperature phase transitions. Due to the speed of data accumulation and a registration over a large solid angle, the method allows to study large numbers of samples. This beamline has become extremely demanded in the chemical, biological, material science, and archaeological community in Russia.
