During this quarter, construction of the four ratings required for the preproduction sample was continued. One of these ratings is now ready for testing. A program to improve the present yield levels was begun. Data obtained so far indicate that reduction of the aging temperature will not solve the problem of room temperature leakage current instability. Investigation of the effects of capacitance and voltage derating are under way. The final data from the reanodization studies indicate that variations in electrolytes and temperatures produce no significant quality improvements. Author
