On the possibility of control the maximum energy of fast neutrons by the pulse height spectra of the 10B‑detector
The possibility of controlling the maximum energy in the neutron flux from the source by analyzing the pulse height spectra from the <sup>10</sup>B detector is investigated. Ionization losses of <sup>4</sup>He and <sup>7</sup>Li nuclei in two detector gaps are simulated. The founded unambiguous experimental dependence of the maximum position and the shape of these spectra on $E_{n}^{{max}}$ and the simulation which is in agreement with it can be used to monitoring $E_{n}^{{max}}$.
