Synchronized Detection of X-Ray and Secondary Fluorescent Radiation of a Sample by Monophoton Sensors

The structure of a device designed to detect X-ray and optical photons ascending from a sample irradiated with synchrotron radiation or X-ray tube radiation and the principles of its operation are described. The operation of the device consists of determining the delay time of the specified optical photons relative to the X-ray photons. Block diagrams of the main components of the device, outlining the principles of their operation, are given: a monophoton X-ray sensor, a monophoton optical sensor, and a unit for determining the time delay. The areas of scientific and applied use of information obtained with the help of the considered device are indicated.
