Abstract : Progress on the program has been slower than desired during this reporting period. The major problem has been that of obtaining parts. Design progress has been satisfactory. The oscillator oven design is being modified because of marginal thermal control in the first prototype. A new design will increase the size by one-half inch in diameter and more insulation will be added. All interface circuit design has been completed. The logic design has been modified to simplify some of the functions. All other circuit design has been completed except the final evaluation of the power output stage of the distribution amplifiers and the -6-volt regulator for the oscillator and main system power supplies. In addition, thermal analyses have been made of the heat rise in each drawer. The heat rise in the oscillator drawer must be kept to a minimum in order to obtain stable, efficient operation in a 50C environment. (Author)
