A user interface is created to monitor and operate the heating, ventilation, and air conditioning system. The interface is networked to the system's programmable logic controller. The controller maintains automated control of the system. The user through the interface is able to see the status of the system and override or adjust the automatic control features. The interface is programmed to show digital readouts of system equipment as well as visual queues of system operational statuses. It also provides information for system design and component interaction. The interface is made easier to read by simple designs, color coordination, and graphics. Fermi National Accelerator Laboratory (Fermi lab) conducts high energy particle physics research. Part of this research involves collision experiments with protons, and anti-protons. These interactions are contained within one of two massive detectors along Fermilab's largest particle accelerator the Tevatron. The D-Zero Assembly Building houses one of these detectors. At this time detector systems are being upgraded for a second experiment run, titled Run II. Unlike the previous run, systems at D-Zero must be computer automated so operators do not have to continually monitor and adjust these systems during the run. Human intervention should only be necessary for system start …

This paper analyzes in detail some theoretical aspects in the modeling of a readout architecture for pixel detectors. In fact, these problems are common to the design of data acquisition systems and other processes containing buffers and where the input and output signals can be expressed by probability density functions. It is the purpose of this paper to point out that the same type of analysis can be extended to other systems with the benefit of saving time in long Montecarlo simulations and prototype design. The example case in which this paper is based on is the readout architecture of a column-based pixel detector amplifier and discriminator chip containing more than 3000 pixels of 50µ x 400µ. Several readout strategies are compared searching for an optimal design, which minimizes data loss and maximizes throughput. In particular, the probability of loosing pixel hits by overflowing the readout system is minimized studying the behavior of the stochastic Marcov process. Also, the communication channel bandwidths and local buffering are optimized.

The APS FEL consists of a series of undulators that must be carefully aligned for optimum gain and high spectral output. In order to get a better understanding of acceptable tolerance levels for undulator alignments and for the electron beam, the authors have performed computer calculations to simulate misalignments of one undulator (undulator number 2) with respect to adjacent undulators and to check the sensitivity to unmatched beam parameters ({alpha} and {beta}) at the entrance and to a noncentered incident beam x{sub o}, x{sub o}{prime}, y{sub o}, y{sub o}{prime}. They have not simulated horizontal misalignments because the undulators focus only in the vertical direction and horizontal alignments are therefore much more relaxed than vertical alignments. The exact placement and strength of the quadrupoles in the breaks need also to be addressed in follow up studies and are not presented here. Further, inherent undulator magnetic field errors have not been investigated here and will also be the subject for another study. Note, the tolerances listed in this note may be used for guidance only and will need to be updated when they have updated beam parameters.

This document shows compliance with DOE order 6430.1A of the 241-SY-101 RAPID Mitigation system. The purpose of this document is to record the design attributes of the RAPID Mitigation System which fulfill the pertinent requirements specified in DOE Order 6430.1A-General Design Criteria. Those pertinent Order requirements which are not met by the project at the time of the release of this document are recorded and noted as open items in Section 4.0-Conclusions.

Photodetectors are widely used in particle and nuclear physics research. Since the beginning of the modern era of photoelectric transducers in the late 1930�s, many types of devices have been developed and exploited for physics research. New performance requirements arising in physics experiments have often provided very interesting technological drivers for industry. New ideas for photo-detection are rapidly adapted by the physics community to enable more powerful experimental capabilities. This report gives a sampling of new developments in photodetection for physics research in the period since the first conference in this series, Beaune 96. Representative examples of advances in vacuum devices, solid-state devices and gaseous photodetectors are described including, where appropriate, an indication of areas where technological improvements are needed or expected.

Hanford Seismic Monitoring provides an uninterrupted collection of high-quality raw and processed seismic data from the Hanford Seismic Network (HSN) for the U.S. Department of Energy and its contractors. Hanford Seismic Monitoring also locates and identifies sources of seismic activity and monitors changes in the historical pattern of seismic activity at the Hanford Site.

The spectrum of heavy-quark hybrids is studied in the leading Born-Oppenheimer (LBO) approximation and using leading-order NRQCD simulations with an improved gluon action on anisotropic lattices. The masses of four hybrid states are obtained from our simulations for lattice spacings 0.1 fm and 0.2 fm and are compared to the LBO predictions obtained using previously-determined glue-excited static potentials. The consistency of results from the two approaches reveals a compelling physical picture for heavy-quark hybrid states.

BTeV is a dedicated beauty and charm experiment proposed for the Fer- milab Tevatron. The broad physics program envisaged for BTeV requires a trigger that is efficient for a wide variety of heavy-quark decays, includ- ing those to all-hadronic final states. To achieve this, we plan to trigger on evidence of detached vertices at the very first trigger level, taking ad- vantage of fast-readout pixel detectors to facilitate fast pattern recognition. Simulations show that 100-to-1 rejection of light-quark background events can be achieved at Level 1 using specialized trackfinding hardware, and that an additional factor of 10 to 100 in data reduction can be achieved using general-purpose-processor farms at Levels 2 and 3. This is adequate to allow data-taking at luminosities in excess of 2 x 10³² cm^-2s^-1.
