Large area silicon sheet by EFG. Third quarterly progress report, April 1, 1976--June 30, 1976

The ''wide'' ribbon machine, JPL No. 1, is satisfactorily nearing completion. Heat sinks to accelerate growth rates were tested. Although horizontal gradients can be tailored with the heat sinks, no growth rate improvement was realized. The electrical effects of linear boundaries have been studied. Thin ribbon growth as an immediate task is reconsidered.
