Initially, it is necessary to give a general concept of the monochromaticity parameter itself, which is often associated with monoenergetics. The whole point is that the beam, after its formation by thermionic, auto- or other emission, has a heterogeneity in energy, which is why the particles in its various regions have different, albeit slightly distinguishable energies. With acceleration, their given spread or gradient increases, although it becomes smoother. For example, on accelerators of the 80s, an example of which is the SOKOL-2 accelerator, monoenergetics of up to 5 keV is achieved at 2 MeV of the total beam energy, while on modern accelerators, at an energy of 20 MeV, an accuracy of up to 1 keV is achieved in maximum accuracy.
