Paper Abstract

Neutrons from a pulsed Training Research Isotope Products General Atomics (TRIGA) research reactor are used to create nuclear reactions in a boron coating on the wall of an irradia-tiJn chamber that surrounds flowing oxygen. This generates high-energy ions that interact with the oxygen, producing the long-lived metastable, 02(1▵). Current experiments use 1 to 5 Torr of 02 in 100 to 200 Torr of Ar carrier gas. The 1.27-μm emission from 02(1▵) is monitored 8 meters from the excitation region and nearly 1 second after the reactor pulse (-10 msec wide). Results to date indicate 02;1M/02(3E) fractions obtained are well above the 17% required to invert iodine in a flowing transfer laser. The 02(1▵)-12 laser is of particular interest as a candidate driver for an inertial confinement fusion reactor. Since energy coupling between the pellet and driver occurs directly through neutrons, rela-tively high system efficiencies appear possible. Further, the long-lived 02(1▵) state provides the energy storage time (fractions of a second) needed between pellet implosions.
