Results of impurity composition investigation of large-area atomic hydrogen beam formed by a low-pressure arc
discharge source with self-heated cathode were cited. The study was performed on 18 metallic elements. Method, based
on measurement of sheet concentration of metal atoms on Si sample surface before and after exposition in atomic
hydrogen flow was used for determination of composition of impurities in atomic hydrogen beam. Measurement of sheet
concentration of metal atoms was realized by ToF SIMS method. The method sensitivity was 108 at. cm-2. Principal
reason of parasitic metal particles occurrence in the beam and the methods for reduction of metal impurity concentration
in ΑH beam was investigated.
