Lithium-containing radiator materials for neutron ionization chambers by Petr B. Baskov, Boris S. Salamakha, Yakov V. Glazyuk, Artur A. Namakshinas, Sergey A. Bondarenko, Ilya M. Mushin, Alexander S. Khudin

“…The paper presents the results of material testing for the purpose of obtaining radiator material – acomposite coating with neutron conversion material – for ionization chambers (IC) which contain the 6Li isotope and convert neutron radiation to a flux of high-energy charged particles through the 6Li(n, α)3H nuclear reaction. The proposed method for forming lithium-containing radiator material allows ensuring a high temperature resistance of up to 600 °C and a mechanical strength at the expense of adhesion to the IC electrode material (grade 321 steel). …”
