Cell for absorption and fluorescence spectroscopy of high-pressure and high-temperature sodium vapor

Abstract

We have constructed a 23-cm-long cell for spectroscopy of high-pressure sodium (and sodium–mercury) vapors at high temperatures. This cell operates in contrast to a heat pipe, without buffer gas. Sodium pressures up to 100 Torr (and mercury pressures up to 3000 Torr) have been obtained at temperatures up to 1500 K.
