205 kA pulse power supply for neutrino focusing horns

Description: A new underground beamline is being constructed at Fermilab to generate and focus a beam of neutrinos on a detector 450 miles away in Soudan, Minnesota. A compact modulator utilizing capacitive energy storage and SCRs as the switching element has been built and tested at Fermilab. The 0.9 F capacitor bank operates at less than 1 kV. It delivers its output of up to 240 kA directly to the two series connected focusing horns via a multi-layer radiation hard stripline [1]. Dual pulse width capabili… more

The 2002 Farm Law at a Glance

Description: On May 13, 2002, President Bush signed the Farm Security and Rural Investment Act (FSRIA) of 2002 into law (P.L. 107-171). FSRIA is the latest in a long line of omnibus, multi-year farm bills. The 2002 law is the successor to the last omnibus measure, the Federal Agriculture Improvement and Reform Act of 1996 (P.L. 104-127). This report, to be updated if events warrant, provides selected highlights.

[3H]Azidodantrolene photoaffinity labeling, synthetic domain peptides and monoclonal antibody reactivity identify the dantrolene binding sequence on RyR1

Description: Dantrolene is a drug that suppresses intracellular Ca2+ release from sarcoplasmic reticulum in normal skeletal muscle and is used as a therapeutic agent in individuals susceptible to malignant hyperthermia. Though its precise mechanism of action has not been elucidated, we have identified the N-terminal region (amino acids 1-1400) of the skeletal muscle isoform of the ryanodine receptor (RyR1), the primary Ca2+ release channel in sarcoplasmic reticulum, as a molecular target for dantrolene usin… more

Abort Gap Cleaning in RHIC

Description: During the RHIC Au-run in 2001 the 200 MHz storage cavity system was used for the first time. The rebucketing procedure caused significant beam debunching in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam could account for approximately 30%-40% of the total beam intensity. Some of it will be in the abort gap. In order to minimize the risk of magnet quenching due to uncontrolled beam losses at the time of a beam dump, a combination of a… more

Abortion: Legislative Response

Description: The primary purpose of this issue brief is to focus on the current legislative action in the 107th Congress with respect to abortion; however, understanding that legislation requires a review of the U. S. Supreme Court’s leading decisions concerning a woman’s right to choose whether to terminate her pregnancy. For a detailed discussion of the case law, see CRS Report 95-724, Abortion Law Development: A Brief Overview.

Abrasive wear behavior of heat-treated ABC-silicon carbide

Description: Hot-pressed silicon carbide, containing aluminum, boron, and carbon additives (ABC-SiC), was subjected to three-body and two-body wear testing using diamond abrasives over a range of sizes. In general, the wear resistance of ABC-SiC, with suitable heat treatment, was superior to that of commercial SiC.

Accelerating and Colliding Polarized Protons in RHIC With Siberian Snakes

Description: We successfully injected polarized protons in both RHIC rings and maintained polarization during acceleration up to 100 GeV per ring using two Siberian snakes in each ring. Each snake consists of four helical superconducting dipoles which rotate the polarization by 180{sup o} about a horizontal axis. This is the first time that polarized protons have been accelerated to 100 GeV. We report on our experiences during commissioning and operation of collider with polarized protons.

Accelerator optimization using a network control and acquisition system

Description: Accelerator optimization requires detailed study of many parameters, indicating the need for remote control and automated data acquisition systems. A control and data acquisition system based on a network of commodity PCs and applications with standards based inter-application communication is being built for the l'OASIS accelerator facility. This system allows synchronous acquisition of data at high (> 1 Hz) rates and remote control of the accelerator at low cost, allowing detailed study of… more

ACCELERATOR PHYSICS MODEL OF EXPECTED BEAM LOSS ALONG THE SNS ACCELERATOR FACILITY DURING NORMAL OPERATION.

Description: The most demanding requirement in the design of the SNS accelerator chain is to keep the accelerator complex under hands-on maintenance. This requirement implies a hard limit for residual radiation below 100 mrem/hr at one feet from the vacuum pipe and four hours after shutdown for hundred days of normal operation. It has been shown by measurements as well as simulation [l] that this limit corresponds to 1-2 Watts/meter average beam losses. This loss level is achievable all around the machine e… more

Active load management with advanced window wall systems: Research and industry perspectives

Description: Advanced window wall systems have the potential to provide demand response by reducing peak electric loads by 20-30% in many commercial buildings through the active control of motorized shading systems, switchable window coatings, operable windows, and ventilated double-skin facade systems. These window strategies involve balancing daylighting and solar heat gains, heat rejection through ventilation, and night-time natural ventilation to achieve space-conditioning and lighting energy use reduct… more

Adaptive Response Against Spontaneous Neoplastic Transformation In Vitro Induced by Ionizing Radiation

Description: response curve for radiation-induced neoplastic transformation of HeLa x skin fibroblast human hybrid cells in vitro under experimental conditions where an adaptive response, if it were induced, would have an opportunity to be expressed. During the first two years of the grant an exhaustive series of experiments were performed and the resulting data were reported at the 2000 Annual Meeting of the Radiation Research Society and then subsequently published (Redpath et al., 2001). The data showed … more

The Advanced Photon Source linac modulators PSpice simulation and upgrade.

Description: The APS linac modulators provide DC pulses to Thales 35/45-MW klystrons. The modulators are pulse forming network (PFN)-type pulsers with EMI 40-kV switch-mode charging supplies. The PFN consists of two 8-cell lines connected in parallel. EEV CX1836A thyratrons are used as discharge switches. The PSpice simulation of the modulators using OrCAD release 9.1 made it possible to find appropriate parameters of RC circuits that reduce high-frequency ringing of the pulse transformer primary voltage.

Afghanistan: Current Issues and U.S. Policy Concerns

Description: The United States and its allies are helping Afghanistan emerging from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and… more

Agricultural Trade Issues in the 107th Congress

Description: The 107th Congress is considering trade issues with implications for the U.S. agricultural sector. Trade in agricultural commodities and food products affects farm income and rural employment, and it also generates economic activity beyond the farm gate. With agricultural export sales the equivalent of one-quarter of farm income, some policymakers view U.S. efforts to develop market opportunities overseas as vital to the sector’s financial health. Decisions taken by the Bush Administration, and… more
