Removal of nitrogen oxide in spatially isolated chamber by pulsed intense relativistic electron beam

Nitrogen oxide (NO/sub x/) in a chamber spatially isolated from beam source has been removed by a pulsed, intense, relativistic electron beam (PIREB). The chamber is filled up with dry-air-balanced NO/sub x/, and is irradiated by the PIREB (2 MeV, 2.2 kA, 85 ns) passing through 1.6-m-long atmosphere. The NO/sub x/ concentration decreases from 88 to 25 ppm by ten shots of PIREB.
