Assessment study of superconducting fault-current limiters operating at 77K

Description: The possible impact of nitrogen-cooled superconductors on the design and cost of superconducting fault-current limiters is assessed by considering the technical specifications such devices must meet and by comparing material properties of 77-K and 4-K superconductors. The main advantage of operating superconductors at 77 K is that the refrigeration operating cost is reduced by a factor of up to 25, and the refrigeration capital cost is reduced by a factor of up to 10. The heat capacity of 77 K … more

Network load of X terminals at CDF

Description: As an aid to planning future usage of X terminals, the authors measured the network bandwidth used by X terminals on a single Ethernet in a typical application environment at Fermilab. The objectives were twofold. The first objective was to identify the impact of adding one more X terminal onto the CDF Ethernet . The second objective was to determine the maximum number of X terminals allowable on the CDF network. The findings reveal that an X terminal in this environment used, on average, 431 +… more

Induced cycle structures of the hyperoctahedral group

Description: The hyperoctahedral group B{sub n} is treated as the automorphism group of the n-dimensional hypercube, denoted Q{sub n}, which is nowadays understood to be a graph on 2{sup n} vertices. It is well-known that B{sub n} can be represented by the group of signed permutations. In other words, any signed permutation induces a permutation on the vertices of Q{sub n} which preserves adjacencies. Moreover, signed permutations also a permutation group on the edge of Q{sub n}, denoted H{sub n}. We study … more

Very high energy gamma ray astrophysics

Description: The second reflector (project GRANITE) is on schedule. At present (January 1992) it and the 10 m reflector are obtaining stereoscopic views of gamma-ray air showers from the Crab Nebula which verify the expected performance of the twin reflector telescopes. With the additional improvements of the upgrade (a pending DOE proposal) the twin reflectors should reach a limiting intensity of 1% that of the Crab. The astonishing early results from the EGRET detector aboard the Compton Gamma Ray Observa… more

Experimental investigation of steep-front short duration (SFSD) surge effects on power systems components

Description: Results are reported from experiments in which steep-front, short- duration (SFSD) voltage impulses were imposed on various electrical distribution components. These pulses were generated by switching a section of charged, high voltage coaxial cable across the component under study. Components included underground distribution cable, terminators, insulators and arresters. SFSD voltage needed to flashover 15 kV polyethylene cable with a single pulse is approximately 625 kV peak. Strength of poly… more

HEMP-induced transients in electric power substations

Description: A nuclear detonation in or above the earth's atmosphere produces an intense electromagnetic pulse (EMP). A large portion of the EMP electromagnetic energy is within the RF spectrum. A detonation at high altitudes above 40 km produces an EMP called high-altitude EMP (HEMP). HEMP is a steep-front short duration transient with a rise time on the order of a few nanoseconds which decays to near zero in less than a microsecond. A single high-altitude burst can subject much of the continental United S… more

High performance parallel local memory computing at Fermilab

Description: Both experimental and theoretical approaches to high energy physics (HEP) at Fermilab are computer technology limited: no one can identify a requirement on computing or data capacity that is independent of cost or other realities. Fermilab has been forced, therefore, to turn significant attention and resources to finding extremely cost effective solutions to its computing using whatever technology is available, and in the process has become a pioneer in goal-driven computer science, integrating… more

The network observer: A user's manual and programmer's guide for the und xb code

Description: A computer program that will yield graphic displays of a variety of statistics simultaneously for 13 emeters has been created. It runs on the SUN computer and uses Dunigan's xtraffic.c code and the xmx code written at Brown University to multiplex these graphs to users at remote sites. By operating in this manner the remote user gets the information without having to query the emeter directly. The emeter is then not overloaded by requests for information, and the operation of the network is mor… more

Magnetohydrodynamic electromagnetic pulse (MHD-EMP) interaction with power transmission and distribution systems

Description: This report discusses the effects of the late-time high-altitude electromagnetic pulse (HEMP) on electrical transmission and distribution (T D) systems. This environment, known as the magnetohydrodynamic electromagnetic pulse (MHD-EMP), is a very slowly varying electric field induced in the earth's surface, similar to the field induced by a geomagnetic storm. It can result in the flow of a quasi-dc current in grounded power lines and in the subsequent magnetic saturation of transformers. This s… more
