The complexity of this method lies in severe ill-posedness of the inverse problem of reconstruction the spectrum from the beam absorption. The task of our work is the operational control of the spectrum of a beam with the maximum energy up to 300 keV. The current collector package consists of 16 insulated identical aluminum foils with the 1 mm gap between. The thickness range of the foils is 10 to 25 microns, depending on the maximum electron energy. The charge of the foils after passing the beam is measured by the ADC. The assembly geometry was calculated by the Monte Carlo method to determine the accumulation of charges on foils when monoenergetic beams are transmitted in the range from 10 to 300 keV with step increment of 10 keV. The inverse problem was solved by Tikhonov regularization. It turned out that a high-accuracy fitting of the input data and the transformation kernel by statistical distributions is the primary factor, which allows to reduce the regularization parameter to almost zero. The validity of the technique applied is confirmed by the fact that the spectrum obtained at the maximum electron energy of the beam of 250 keV is in satisfactory agreement with the spectrum measured on a magnetic spectrometer.
