Conclusions Investigations of the phton current in neutron ionization chambers have shown that the main contribution stems from positive ions. Investigations made with the mass spectrometric technique to determine the composition of those ions have led to the conclusion that a significant portion of the ions emitted from a surface which had been heated for 5 h are hydrocarbon ions. This is a consequence of the ionization of the molecules of the material of which the residue of the binder is composed. Prolonged heating (25 h) makes it possible to eliminate hydrocarbon lines from the mass spectrum. However, the spectrum still comprises lines resulting from the current of the K+ ions which determine the lower limit of the phonon current in neutron chambers.
