A theory of pulse-periodic radiative high-pressure cesium discharge

The gasdynamics of pulse-periodic discharge in high-pressure cesium vapor has been self-consistently modeled for the first time. The discharge is an effective light source with a continuous spectrum and a luminous efficacy of eta(V) = 74 lm /W. Under conditions where the optical thickness of plasma in most part of the spectrum is close to unity, the main mechanisms of energy transfer in the discharge volume are nonlocal radiative heat exchange and radiative heat conduction.
