Abstract
The problem of creation of the most effective high intensity x-ray radiation sources for a digital diagnostics in medicine and other fields remains actual till now. In the work, experimental results on design of digital radiographic set-up based on the betatron MB-6 bremsstrahlung source are presented. Betatron has the following parameters: electron energy is 6 MeV, beam current is 100 nA, frequency is 50 Hz, dose rate on bunch axis is 35mG/minute at distance 1m, thickness of tantalum target is 0,6 mm. The set of 640 gallium arsenide detectors with size 0,2×0,2×2 mm3 with sensitivity in photon energy range up to 200 keV was used. The digital images of investigated object have been received by scanning technique. The result obtained show that use of thin betatron target allows to avoid a self-absorption of bremsstrahlung photons with energy < 200 keV in a target. It will lead to increase in the detector sensitivity and reduce an exposition time to achieve high level image quality and pattern contrast.
