Abstract : The pilot production phase of the program was completed. Sixty-nine barrier grid tubes passed complete specification testing and were placed in stock. The low beam current problem was resolved and the single beaded barrier grid gun is now a standard, reliable assembly. The major cause of reject tubes remains defective targets. Although the situation was somewhat improved during this quarter, some further work is still needed in this area, if tube yields above the current 35% to 40% are to be realized. (Author)
