Development of the CARS method for measurement of pressure and temperature gradients in centrifuges

These experiments evaluated the feasibility of applying the CARS technique to the measurement of UF/sub 6/ concentrations and pressure gradients in a gas centrifuge. The resultant CARS signals were properly related to system parameters as suggested by theory. The results have been used to guide design of an apparatus for making CARS measurements in a UF/sub 6/ gas centrifuge. Ease of measurement is expected for pressures as low as 0.1 torr. Temperature gradients can be measured by this technique with changes in the data acquisition method. 16 references, 8 figures, 2 tables.
