Determination of X-ray tubes radiation beam characteristics with semiconduictor pixel detectors

Popis výsledku v původním jazyce

X-ray tubes belong among the most important sources of ionizing radiation and are used in various applications and methods, i.e. investigation of materials, diagnostics in medicine, irradiations, etc. The exact properties of X-ray sources or their X-ray beams need to be known also when Monte Carlo simulations of experimental setups are considered with the aim of optimization or calibration of X-ray systems. These properties are X-ray spectra, beam profiles, divergence and homogeneity of beams. Properties of low power X-ray tubes with the maximum voltage up to 50 kV were investigated in this study. These devices included a small laboratory X-ray tube with collimated X-ray beam and microfocus X-ray tube with polycapillary focusing optics. Beam shape features were reconstructed from a silicon pixel detector response. The pixel detector was inserted into X-ray beams at different distances from X-ray sources. Beam 2D profiles were obtained and since the pixel detector worked in a single event detection mode, approximate energy of individual photons could be measured besides the position of their detection. In this way, detailed information about the beam properties was obtained.
