THE MEASUREMENT AND CHARACTERIZATION OF PRIMORDIAL GRAVITATIONAL WAVES (PGWS) FROM THE EPIC OF INFLATION IS ONE OF THE MAJOR GOALS IN COSMOLOGY. THESE PGWS LEAVE A SIGNATURE ON THE POLARIZATION OF THE COSMIC MICROWAVE BACKGROUND (CMB) CALLED THE PRIMORDIAL "B-MODES." FULLY CHARACTERIZING THIS SIGNATURE WILL REQUIRE SUBSTANTIAL TECHNOLOGICAL DEVELOPMENT TO ACHIEVE SENSITIVITIES COMPARABLE TO ONE BILLIONTH THE SIZE OF THE UNPOLARIZED SIGNAL. I WILL DEVELOP SEVERAL TECHNOLOGIES THAT WILL BE REQUIRED FOR THE POSSIBLE SPACE MISSION OUTLINED IN THE NASA EPOCH OF INFLATION TECHNOLOGY PUSH THROUGH MY WORK ON THE COSMOLOGY LARGE ANGULAR SCALE SURVEYOR (CLASS). CLASS IS A GROUND BASED TELESCOPE ARRAY THAT WILL MEASURE THE POLARIZATION OF THE CMB TO UNPRECEDENTED ACCURACY. THE INSTRUMENTATION THAT I WILL DEVELOP AND TEST ON CLASS WILL RAISE THE TECHNOLOGY READINESS LEVEL OF SEVERAL INSTRUMENTS RELEVANT TO THE EPOCH OF INFLATION TECHNOLOGY PUSH. CLASS USES EXTREMELY SENSITIVE ANTENNA-COUPLED TRANSITION EDGE SENSORS AND A RAPID FRONT-END POLARIZATION MODULATOR TO MAKE A MULTIFREQUENCY MEASUREMENT OF THE POLARIZED CMB ON THE LARGEST ANGULAR SCALES. BY MEASURING THE PEAKS IN THE PRIMORDIAL B-MODE POWER SPECTRUM CLASS WILL CHARACTERIZE THE PGW SIGNATURE WITH GREAT ACCURACY. THE CHARACTERIZATION OF PGWS FROM THE EPOCH OF INFLATION WOULD HAVE TRANSFORMATIVE EFFECTS ON THE FIELD OF COSMOLOGY. THE TECHNOLOGICAL ADVANCES MADE THROUGH THE DEVELOPMENT OF CLASS WILL ACHIEVE THIS MEASUREMENT WHILE SIMULTANEOUSLY RAISING THE TECHNOLOGY READINESS LEVEL FOR FUTURE MISSIONS.
