Summary
The object of this research is to assess the applicability of the photon catalysis technique for effecting composition analysis of silicon samples. In particular, our technique is to be evaluated as a detector for the impurities Al, Cr, Fe, Mn, Ti, V, Mo, and Zr. During the first reporting period Al, Cr, Fe, and Mn were detected with the photon catalysis method. The best fluorescence lines to monitor were established and initial sensitivities to each of these elements by atomic absorption calibration were determined. In the course of these tests vapor pressure curves for these four pure substances were also mapped. During the second quarter Ti and Si were detected with the technique. The best lines to monitor were cataloged and vapor pressure curves were determined. Attempts to detect vanadium were unsuccessful due to the refractory nature of this element and the limited temperature range of the evaporator.
