The invention provides atomic oxygen simulation equipment based on a Hall principle, which comprises an oxygen supply system, an ion absorption electrode, a Hall ion source, an electron source, a power supply, a vacuum pumping unit, a test bed and a true air container, and is characterized in that the power supply is connected with the Hall ion source, and the ion source and the ion absorption electrode are arranged on an air path of the Hall ion source; the Hall ion source is introduced into the oxygen supply system, oxygen is ionized to generate oxygen ions, the oxygen ions are emitted under the action of an electric field and a magnetic field to be led out of the Hall ion source, and electrons are emitted through the electron source on a gas path to neutralize the oxygen ions to form atomic oxygen. Oxygen ions and electrons which are not neutralized are absorbed by the ion absorption electrode under the action of the deflection electric field, atomic oxygen is fed into the test bed to act on an atomic oxygen test sample, and the gas path of the Hall ion source, the ion absorption electrode of the ion source and the test bed run in the vacuum container. According to the atomic oxygen simulation equipment based on the Hall principle, the atomic oxygen proportion of a neutral atomic oxygen beam is high; the atomic oxygen flux is convenient to adjust; and the device is not provided with a microwave component and has no harm to the body of a tester.
