In Machines 17 and JPL No. 1, experiments are being continued to better understand the limitations on growth speeds over 4 cm/minute, imposed by the details of the present cartridge design. Also, work is progressing on the uniform introduction of oxygen into high-speed growth systems and the resulting 10 cm wide ribbon. In the multiple furnace (3A), further progress in understanding the obstacles preventing the technical features demonstration has been made; this is reported in detail. In the characterization area, a principal result has been to verify the reproducibility of the behavior of oxygen enriched ribbon insofar as thermal processing during solar cell fabrication is concerned.
