The design and preliminary testing of a metal strip and a dielectric sheet beam splitter was accomplished in this quarter. Fabrication of a beam splitter is a difficult task because of the necessity of preserving the resonator Q with the beam splitter installed. This problem is discussed. Several asymmetric gases for use in the totally resonant are still under investigation. Because of the corrosive and toxic properties of many of these gases, emphasis has been placed on a search for a gas with the proper energy levels that can be handled in a conventional vacuum system. A tabulation of gases under consideration, and their toxicity and handling problems, is given in the body of this report. Methylene chloride, methylene fluoride, and difluoroethylene appear to have the best handling characteristics. A possible scheme for pumping methylene chloride has been found. Further evaluation of the other gases has been started. Energy levels for methylene fluoride, difluoroethylene, formaldehyde, vinyl cyanide, benzonitrile and nitrosyl chloride are given in Appendix A. A nickel monel vacuum system was constructed to test the corrosive properties of these gases. The experimental effort is reviewed. Major emphasis was placed on high power tests for the two-level scheme and parallel plate interferometer and beam splitting tests for the totally resonant system.
