EXPERIMENTAL AND THEORETICAL RESEARCH IN GRAVITA TION PHYSICS.
Abstract
Research has continued on the generator of dynamical gravitational fields, in the vicinity of 1657 cycles per second. The generator con sists of an aluminum cylinder, 8 inches in diameter, 60 inches long, suspended in a vacuum chamber. A vacuum tube oscillator drives piezo electric crystals secured to the cylinder, and the cylinder is excited in its lowest compres sional mode. A principal objective of our research was accomplished. The cylinder was successfully driven at strain amplitudes as high as 5 x 1/10,000. It can be reliably driven at strain amplitudes of 2 x 1/10,000. We observed that temperature drift of the cylinder resulted in a drift of its resonant frequency. A dis cussion is given ff the calculation, measurement, and control of the temperature. This control is essential in order to guarantee that the resonant frequency of the generator will be within the pass band of detection apparatus which measures the dynamirvature tensor. A summary is given of theoretical research directed towards the quantization of General Relaivvity, follow ing up the work of Dirac on the constraints and Hamiltonian formulation. (Author)
