Measurement of intense X-Ray spectra: Methods based on CXR and Ross filter

The interaction between X-ray radiation and the material of secondary targets is simulated using GEANT4 for two methods of measurements of intense X-ray spectra. In the first case, characteristic X-ray radiation (CXR) from the secondary target to the back hemisphere is detected; in the second case,...

Description
Summary:The interaction between X-ray radiation and the material of secondary targets is simulated using GEANT4 for two methods of measurements of intense X-ray spectra. In the first case, characteristic X-ray radiation (CXR) from the secondary target to the back hemisphere is detected; in the second case, primary radiation passing through pairs of foils (a Ross filter) is registered. Using Ross filters and the CXR technique, the primary spectra of X-ray radiation are recovered. Two methods for recovery primary radiation spectra are compared.
