    The LLNL Nuclear Chemistry Counting Facility (NCCF) is being converted to a modern production facility. A computer network has been designed and built to implement this conversion. The outermost node of the computer network is a dedicated EPROM-based controller. Tne controller handles the details of driving the attached nuclear instrumentation, providing a standard interface to the remainder of the network. This paper addresses the design and the implementation of the dedicated instrunientation controller. View full abstract»

    A data acquisition and experiment control system for experiments at the Biology Small-Angle X-ray Scattering Station at the National Synchrotron Light Source has been developed based on a multiprocessor, functionally distributed architecture. The system controls an x-ray monochromator and spectrometer and acquires data from any one of three position-sensitive x-ray detectors. The average data rate from the position-sensitive detector is ~ 106 events/sec. Data is stored in a one megaword histogramming memory. The experiments at this Station require that x-ray diffraction patterns be correlated with timed stimuli at the sample. Therefore, depending on which detector is in use, up to 103 time-correlated diffraction patterns may be held in the system memory simultaneously. The operation of the system is functionally distributed over four processors communicating via a multiport memory. View full abstract»

  • Analog Signal Processing for the Time Projection Chamber

    The Time Projection Chamber (TPC) is a large gas filled cylindrical detector designed to provide 3-D images of tracks radiating from the center of the detector where e+ e- collisions occur. Ionization along the tracks is drifted in an electric field to the end planes which are equipped with a large array of proportional wires and position pads (17,000 channels). The wire signals are used to derive radial data while the pad signals provide the azmuthal information. The axial dimension is determined using the drift time of the ionization. Preamplifiers mounted in the ends of the chamber feed the signals to remote amplifiers whose outputs drive Charge Coupled Devices (CCD). The CCDs are normally clocked at 10 MHz and hold a 45.5 ¿s history (445 CCD buckets) of analog drift information from the TPC. During readout the clock is changed to 20 KHz and 17,000 CCD outputs are digitized (9 bits) in parallel. The non-zero data is then transferred to buffer memories associated with the digitizers. This paper emphasizes the analog signal processing part of the system. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1815 KB)  

    A microcomputer-based system which executes code in read-only memory (ROM) and is written in the high-level programming language Pascal was developed for the Nuclear Test Program at the Lawrence Livermore National Laboratory. This system is a part of a network of LSI-11 microcomputers which control, monitor, and acquire data from digital measurement devices. The Pascal language itself is a powerful and flexible tool for software engineers in the development of well-structured software that can be easily maintained. This paper describes a technique for developing code in the OMSI Pascal-1 language Which will execute successfully in ROM. View full abstract»

    A study Group of the ESONE Cmmittee has prepared proposals for extensions to the CAMAC Dataway. These extensions allow modules and controllers to exploit microprocessor technology by providing a greatly extended addressing range, logical addressing and handshake timing in a manner that is compatible with existing CAMAC equipment. This paper describes the specifications that have been prepared by the COMPEX Study Group and relates the potential application areas to those of "standard" CAMAC. View full abstract»

    An efficient method of interprocessor communication between a Digital Equipment Corporation LSI-11 minicomputer and an Intel 8085 microprocessor has been developed for a multiprocessor environment. In this method, which optimizes the handling of transactions between the two processors, an LSI-11 minicomputer interrupts the execution of the 8085 microcomputer under hardware control to place data directly in 8085 memory. Details of hardware implementation and interprocessor communication blocks are presented. View full abstract»

    At the same time as the FSDG (Fast System Design Group) started its work in the USA, the ESONE Committee set up the ASSG (Advanced System Study Group) in Europe. The ASSG followed closely the work of the FSDG. The ASSG meets about three times a year to coordinate the development effort in European laboratories. Active work has started now throughout Europe, especially at CERN where a number of system modules are under development. Further, a one crate pilot system for use in a physics experiment is near completion. The status of this work will be summarized View full abstract»

  • The FASTBUS Segment Interconnect

    The FASTBUS Segment Interconnect provides a communication path between two otherwise independent, asynchronous bus segments. In particular, the segment interconnect links a backplace (crate) segment to a cable segment. All standard FASTBUS address and data transactions can be passed through the SI, or any number of SI's and segments in a path. Thus systems of arbitrary connection complexity can be formed, allowing simultaneous independent processing, yet still permitting devices associated with one segment to be accessed from others. The model S1 segment interconnect being built at the University of Illinois supports these and other important features. View full abstract»

    A detector is being constructed at Fermilab to investigate antiproton - proton collisions at up to 2 TeV center of mass energies. The detector will have approximately 75,000 channels of electronics with an expected occupancy of about 10% for typical events. The ultimate raw event rate is expected to be 50 KHz, with events being written to magnetic tape at a rate of 5 Hz. We are designing a FASTBUS based data acquisition system incorporating multiple processors running concurrently to do the necessary data compaction and filtering. Numerous local intelligences allow the system to be broken into independent subsystems for checkout and calibration. View full abstract»
