A prototype in-situ instrument for real time depositon diagnostics is being built and tested. It uses Fourier Transform infrared spectroscopy (FT-IR) to determine: substrate temperature, phase changes, film thickness, water contamination, trends in oxygen content, grain size, and both ambient gas concentration and temperature. In addition to its use for high temperature superconductor depositon, the instrument has application in other deposition and coating processes and annealing reactors. It can be used to improve process quality control, lower production costs, and aid the research in new materials.
