[en] The purpose of this paper is to describe the architecture and performance of the Event Handler, a fast, programmable data acquisition interface which is linked to and through CAMAC. The special features of this interface make it a powerful tool in implementing data acquisition systems for experiments in nuclear physics

[en] An insert for a nuclear fuel pin which comprises a strip. The strip carries notches, which enable a coding arrangement to be carried on the strip. The notches may be of differing sizes and the coding on the strip includes identification and identification checking data. Each notch on the strip may give rise to a signal pulse which is counted by a detector to avoid errors. (author)

[en] The project reported deals with one of the aspects of power plant control and management. In order to perform optimal distribution of power and load switching, one has to solve a specific optimization problem. In order to solve this problem one needs to collect current and power expenditure data from a large number of channels and have them processed. This particular procedure is defined as data acquisition and it constitutes the main topic of this project. A microprocessor-based data acquisition system for power management is investigated and developed. The current and power data of about 100 analog channels are sampled and collected in real-time. These data are subsequently processed to calculate the power factor (cos phi) for each channel and the maximum demand. The data is processed by an AMD 9511 Arithmetic Processing Unit and the whole system is controlled by an Intel 8080A CPU. All this information is then transfered to a universal computer through a synchronized communication channel. The optimization computations would be performed by the high level computer. Different ways of performing the search of data over a large number of channels have been investigated. A particular solution to overcome the gain and offset drift of the A/D converter, using software, has been proposed. The 8080A supervises the collection and routing of data in real time, while the 9511 performs calculation, using these data. (Author)

[en] Major components and primary functions of the process control system for the K/sub 1C/-HSST irradiation experiments at the Oak Ridge Research (ORR) are described. Information relative to methodology for integrating unique features of the Digital Equipment Corporation's RSX-11M Operating System with analog-to-digital and digital-to-analog hardware is presented. In particular, data flow among various real-time applications programs relative to system hardware is presented. General features of the temperature control algorithm are presented, and results that illustrate the spatial temperature distribution in the capsule achieved by the control system are included

[en] The aim of this work is to develop a system which allows visualising the operational parameters of the RA-0 nuclear reactor. These parameters are stored in a postgresSQL database by an Electronic Data Acquisition System. The development process must accomplish the following two objectives: 1) Let the researchers of the RA-0 and ARN analyze the data. 2) Allow to use the data provided by this system for teaching purposes (specifically nuclear physics). The application has been developed with flexible features in order to allow being implemented in all nuclear reactor of Argentina. To achieve this, is necessary replicate the IT RA-0 environment in the desired nuclear reactor. In the final job are specified the requirements of the RAXConsult, the development and testing procedures and the development methodology for the entire building application process. Also, are listed the improvements with the system implementation and the future of this project. (author)
