Abstract : With the prototype broadband microwave spectrometer, covering in a continuous manner the frequency range between 8.2 and 40 kmc (0.75 to 3.66 cm wavelength), constructed earlier under this contract, as a starting point, salient modifications have recently been made which increase the sensitivity and stability of the existing system. Frequency stabilization of the microwave oscillator, capability of direct frequency measurement to electronic counter accuracy, power leveling and phase-sensitive detection have been incorporated. A design for a broadband spectrometer operating in the range between 50 and 75 kmc (0.4 to 0.6 cm), and extension of this capability to the harmonic range (0.2 to 0.3 cm) has been completed; frequency stabilization of these systems is accomplished by injection phase-locking from the stable 8.2 to 40 kmc referred to above.
