dc.description.abstract Presented herein are the parts application analysis results as performed on the Lunar Mass Spectrometer. Parts application analysis worksheets are presented in Appendix A for BxA and in Appendix B for UTD. The A Revision herein has been updated to include the Lock Out Switching Circuit (page 190). The B Revision applies to the Flight Model only and is different in that the Flight Model has the Multimode Emission Control Ion Source Voltage (Assembly #151-550) while the Qual Model has the Fixed Mode Emission Control Ion Source Voltage (Assembly #151-700). Both Emission Control Assemblies are electrically interchangeable.
