Abstract
A method and system for producing a neutral beam of spin polarized Hydrogen isotopes by photodissociating compound molecules are provided. Each compound molecule comprises a Hydrogen isotope and a second element. A molecular beam is generated by passing the compound molecules through a nozzle. The molecular beam is introduced into a photodissociation chamber. The molecular beam is photodissociated into spin polarized Hydrogen isotopes and second elements by intersecting the molecular beam with a circularly polarized photolysis laser beam. The spin polarized Hydrogen isotopes are guided, accelerated, and neutralized.
