Gas cell for fundamental spectroscopic measurements over 200-5000 nm, 280-2000 K, and 0.0001-30 bar
Abstract
We have developed a sapphire-based optical cell that can maintain uniform gas samples at temperaturesup to 2000 K. In a prototype cell operating at 1723 K and 0.02 bar, we have recorded high resolution H2Oabsorption spectra spanning 1280 ~ 1365 nm. Until now, it has not been possible to obtain such referencespectra: shock tube studies cannot access such low pressures, and the short test times are crippling. Wepropose to upgrade the prototype to a cell facility that can host measurements of fundamental spectraover the 220 ~ 5000 nm range for numerous gas species such as H2O, OH, CO2, CO, and NO, over 280 ~2000 K and 0.0001 ~ 30 bar. Spectra will then be recorded in the cell, and used to update spectroscopicdatabases such as HITRAN/HITEMP
