The invention discloses a large-
irradiation-area
atomic oxygen beam
simulation system. The
system comprises a water-cooled
electromagnetic field system, a
microwave generation and
transmission system, a
molybdenum neutralization plate, a
water cooling system, a vacuum system and a target base mechanism, wherein the water-cooled
electromagnetic field system can generate a strong
magnetic mirror field which can reach 1,200 gausses; the frequency of the
microwave generation and
transmission system is 2.45GHz and the power of the
microwave generation and
transmission system can reach 1,000W; the microwave generation and transmission system can excite working
oxygen to ionize in the strong
magnetic mirror field to generate and restrain high-density
oxygen plasma; major axis length and
minor axis length of the
molybdenum neutralization plate are 200mm and 140mm respectively; the
molybdenum neutralization plate is used for accelerating, collecting and reflecting positive ions in the
plasma to form a directional
atomic oxygen beam of which the sectional area
diameter is more than 150mm; the
water cooling system can guarantee that an
atomic oxygen source can uninterruptedly and stably workfor 100 hours; the vacuum system is used for guaranteeing a vacuum condition for normal work of atomic
oxygen; and the target table mechanism is used for placing a
test sample in an atomic oxygen beam region. The system guarantees that a device can continuously and stably run in a high atomic oxygen beam state through measures in aspects of cooling, sealing,
material selection and the like. By using the system, the atomic oxygen
environmental adaptation testing efficiency of an
aerospace material can be greatly improved, the test period is shortened, the test cost is reduced, the technical
bottleneck of component-level atomic oxygen test can be broken through, and a
simulation means is provided for more effectively verifying reliability of
spacecraft design.
