Title: Foil moderated radioactive preionization system for gas lasers

Technical Report ·
OSTI ID:5148547

radioactive preionization system is described. It has a thin metallic film or foil, either placed in front of, or deposited on the surface of radioactive sources, in order to isolate the radioactive source from laser discharge regions and to produce copious secondary emission electrons. The film or foil prevents bombardment of the radioactive source by discharge electrons and/or ions. In addition, the secondary emission electrons ejected from the metallic film or foil are more numerous than the radioactive decay particles which produce them and have lower energies. Hence, they are much more efficient preionization agents than the high energy particles emitted by the radioactive source.
