Advisor: Shaul Hannany. 1 computer file (PDF); vi, 43 pages, appendices A1-A3.We investigated the behavior of an Ebert-Fastie spectrometer using reflected ruled diffraction gratings in the 150-410 GHz band for calibration of the E and B EXperiment (EBEX). This behavior is modeled with the simulation software PCgrate. Comparisons show that the experimental and simulated results had significant differences.en-USEbert-FastieEBEXThesis or Dissertation
