Expansion of the exciting radiation range of the EhS-2401 electron spectrometer

A scheme is described of a modernized anode which is an X radiation source in the EhS-2401 electron spectrometer. The anode has two working surfaces, situated at the angle of 140 deg. Magnesium and zirconium emitting surfaces are welded to the working surfaces. A window with aluminium and beryllium filters is established between the anode and a sample under investigation. The anode design permits to generate X radiation with the energies of 151.4, 1253.6 and 2042.4 eV. 3 refs., 1 fig
