Abstract : A temperature regulator for lead sulfide infrared detectors was designed and built. The detector itself was used as the temperature sensing device in the control system. Cold nitrogen gas was used to cool the detector to a temperature below the operating point. A heat exchanger, mounted between the cold source and the detector, warmed the detector to its operating temperature. This regulator and detector were used to study the energy transfer process which takes place between vibrationally excited nitrogen and carbon monoxide at low pressures. The rate constant for the transfer process was determined for the carbon monoxide overtone region between 2.3 and 2.5 microns. (Author)
