Abstract
A halogen mass flow rate detection system having an absorption cell through which a halogen entrained inert gas can be passed. An electromagnetic beam of preselected wavelength in the bound-continuum absorption region is passed through the cell while the halogen entrained inert gas is passed therethrough and also while only an inert gas is passed through the cell. By measuring the intensity of the beam passing through the absorption cell, molecular absorption can be utilized for determining the concentration and, therefore, the mass flow rate of the halogen passing through the absorption cell. By incorporating the halogen mass flow rate detection system in an iodine/oxygen chemical laser, for example, the mass flow rate of the iodine into the resonant cavity of the laser can be simply, accurately and reliably ascertained.
