Isotope Brayton ground demonstration testing and flight qualification. Volume 1. Technical program

Description: A program is proposed for the ground demonstration, development, and flight qualification of a radioisotope nuclear heated dynamic power system for use on space missions beginning in the 1980's. This type of electrical power system is based upon and combines two aerospace technologies currently under intense development; namely, the MHW isotope heat source and the closed Brayton cycle gas turbine. This power system represents the next generation of reliable, efficient economic electrical power … more

Chemical analysis of TATB. Progress report, October--December 1974

Description: Progress during October through December 1974 in research on chemical explosives is reported. The kinetics of the base hydrolysis of TATB has been studied as a function of hydroxide concentration and temperature. The initial rate of hydrolysis expressed as k(OH/sup -/) was determined by extrapolation to zero time. The values of the hydrolysis constant k determined at three temperatures were 3.24 x 10/sup -6/hr/sup -1/ (50 C), 2.22 x 10/sup -5/ hr/sup -1/ (75 C) and 2.05 x 10/sup -4/ hr/sup -1/ … more

Study of Photoproduction of Vector Mesons on Deuterium by 5. 5 GeV Linearly Polarized Photons

Description: The experimental results of a deuterium bubble chamber photoproduction study of half a million pictures at 5.5 GeV are presented. This experiment has been performed using a monoenergetic and linearly polarized photon beam facility at SLAC. At 5.5 GeV the beam polarization is greater than 90%, and the average FWHM of the beam energy spectrum is 0.6 GeV. The reaction ..gamma..d ..-->.. ..pi../sup +/..pi../sup -/d has been studied in detail. A clear sample of ..gamma..d ..-->.. rho/sup 0/d c… more

Staging with spatial filters

Description: It is known that small scale beam instabilities limit the focusable energy that can be achieved from a terawatt laser chain. Spatial filters are currently being used on CYCLOPS to ameliorate this problem. Realizing the full advantage of such a filter, however, may require certain staging modifications. A staging methodology is discussed that should be applicable to the CYCLOPS, 381, and SHIVA systems. Experiments are in progress on CYCLOPS that will address directly the utility of the proposed … more
