AUTOMATIC FOIL ACTIVITY COUNTING FACILITY AND DATA-REDUCTION PROGRAM
A transistorized automatic counting and recording system was built for the determination of foil-activation data. Output data are on IBM-printed and punched cards which may be processed by a high-speed computer. The computer produces tabular and graphical output, as well as punched data cards which may be used for further processing such as curve fitting. The foil-activation data are taken from one to six chains operating in unison (normally samplechanger, detector, amplifier, analyzer, scaler, and readout chains). Circuitry and logic of the system were greatly simplified by the use of a one-second interval marker which initiates and terminates each step of the cycle in full seconds rather than frictionai seconds. The equipment includes provision for optional preset counting interval or preset count accumulition. There are sensing devices to record the kind of measurement made (whether foil activation or background count), plus manual switches which may also specify how individual measurements will be processed later by the computer, on a card-by-card ind scaler-by-scaler basis. Data are processed by an IBM-704 computer programmed to produce plotted traverses as weil as tabular data. From 25 to 100 foilactivation measurements per minute may be processed, depending on the number of entries per card and the use of preprocessing equipment. The data reduction includes many repetitive steps which the computer does very precisely and economically. (auth)
