Spatial Resolution of Images and Effective Focus Size of Bremsstrahlung of an Improved Compact Betatron SEA-2 with Electron Energy of 2.5 MeV
Abstract
Abstract Experimental results on determining the spatial resolution and contrast sensitivity of radiography using Bremsstrahlung from an improved compact SEA-2 betatron with a maximum Bremsstrahlung energy of 2.5 MeV are presented. The measurements were performed using an AGFA NDT D4 Pb VacuPac X-ray film and a Duplex IQI image quality indicator (model EN 462-5). The results obtained with magnification coefficients K = 2.3 and 3.3 of the Duplex IQI indicator images show resolutions of 0.16 and 0.2 mm of pairs of thin wires of the indicator. The effective horizontal size of the radiation focus (approximately 0.3 mm), as well as the vertical size of the radiation focus (approximately 2 mm), which is perpendicular to the plane of the electron orbit, is estimated.
