Inverse problems of high-current electronics

During electron beam impinge on taget a powerful continuous bremsstrahlung (B) is generated. The study of spectral composition of B is of great importance when investigating dynamics in diodes of high-current electron accelerators. Using absorbers and semiconductor detectors B absorption curves are obtained. It is shown that the problem of B spectral power determination is reduced to the Fredholm integral equation of the first type, and the problem of function reconstruction of electron beam energy distribution - to integral equation of convolution type. To obtain absorption curves the method of absorbers was used. For numerical solution of the Fredholm equation of the first type the iterative method was used. The reconstruction of energy distribution function of electron beam was realized using the developed method of inverse linear superposition. B spectra in the absolute units with a high time resolution are measured. Electron beam energy distribution functions are reconstructed
