A successful high shock test on the first model completed its testing program. Upon its completion, nine units were assembled for a complete specification checkout. Theoretical and experimental studies were conducted to determine the characteristics of four taut bands. Three of these bands were selected on the basis of these studies for the nine units. Theoretical studies of terminal resistance compensation indicated that a deviation of nearly 1 can be achieved. Two forms of shielding -- a nickel mesh and conducting glass -- will be tested for shielding effectiveness against electromagnetic interference. The testing program for the nine units began at the close of the quarter.
