FIELD: electricity.
SUBSTANCE: layer of material, for example platinum, is deposited on the surface of the electrode fissionable coating of the fission ionization chamber (FIC), with the electrons release operation larger than the electrons release operation from the coating material, containing the elements, that are divided by interaction with neutrons, at that the thickness of this layer is insufficient for the total restriction (fission fragments) for chemical yield into the interelectrode space and is sufficient to reduce the thermal emission of electrons at temperature above 500°C.
EFFECT: provision of the possibility to control the thermal neutron flux density in the output electrical signals at all operation modes of the reactor plant, including the modes under which the ionization chambers should be operated at temperature more than 500 degrees.
