The total report describes three experimental activities in thermal layer experimental development. Volume III contains descriptions of design and experimental work directed toward the use of a flux redirector for a large solar furnace. Successful completion of this design allows testing of soils at above 300 calsq cm sec. An investigation was made of the feasibility of extending the solar furnace source soil blow-off tests reported in Volume I to higher flux levels. Previous work had identified the CNRS solar furnace at Odeillo-Font Romeu, France, as the unique radiant energy source. Accomplishment of the tests would require Design of an optical configuration to direct the solar furnace flux onto horizontal soil samples necessitating a 90 deg redirection Construction of the critical optical and mechanical components and testing in the actual solar furnace environment Design and construct an instrumentation package to measure irradiation and sample response Preparation and characterization of samples and Conducting soil exposure tests and analyzing test data.
