Diagnostics is proposed and developed for measuring the efficiency of stripping a beam of negative ions in a gas stripper of tandem type charged particle accelerator. The coefficient of ion-electron emission during the bombardment of copper by 1 MeV protons was measured. A bending magnet with a horizontal channel was installed which made it possible to place the Faraday cup and absorb a flux of neutrals formed in a stripper as a result of incomplete stripping of negative ions. Diagnostics of the efficiency of a gas stripper was implemented, using the measurement of the electron current emitted from the surface of the Faraday cup when it is bombarded with a directed flux of neutrals and the proton beam current with a DC non-destructive current transformer.
