2-D Modeling of Energy-z Beam Dynamics Using the LiTrack Matlab Program

Description: Short bunches and the bunch length distribution have important consequences for both the LCLS project at SLAC and the proposed ILC project. For both these projects, it is important to simulate what bunch length distributions are expected and then to perform actual measurements. The goal of the research is to determine the sensitivity of the bunch length distribution to accelerator phase and voltage. This then indicates the level of control and stability that is needed. In this project I simulat… more

``24/36/48`` Cathode Strip Chamber layout for SSC GEM Detector muon subsystem

Description: The ``48/48/48`` {phi}-segmentation design for the Cathode Strip Chambers in the GEM Detector produces a number of coverage ``gaps`` in {phi} and {theta}. A revised ``24/36/48`` {phi}-segmentation layout provides increased geometric coverage and a significant reduction in the number of chambers in the detector. This will increase physics performance while reducing the labor costs associated with building and installing chambers in the GEM Detector. This paper documents the physical layout of th… more

120 MW, 800 MHz Magnicon for a Future Muon Collider

Description: Development of a pulsed magnicon at 800 MHz was carried out for the muon collider application, based on experience with similar amplifiers in the frequency range between 915 MHz and 34.3 GHz. Numerical simulations using proven computer codes were employed for the conceptual design, while established design technologies were incorporated into the engineering design. A cohesive design for the 800 MHz magnicon amplifier was carried out, including design of a 200 MW diode electron gun, design of th… more

303-K Storage Facility Closure Plan. Revision 2

Description: Recyclable scrap uranium with zircaloy-2 and copper silicon alloy, uranium-titanium alloy, beryllium/zircaloy-2 alloy, and zircaloy-2 chips and fines were secured in concrete billets (7.5-gallon containers) in the 303-K Storage Facility, located in the 300 Area. The beryllium/zircaloy-2 alloy and zircaloy-2 chips and fines are designated as mixed waste with the characteristic of ignitability. The concretion process reduced the ignitability of the fines and chips for safe storage and shipment. T… more

600 eV falcon-linac thomson x-ray source

Description: The advent of 3rd generation light sources such as the Advanced Light Source (ALS) at LBL, and the Advanced Photon Source at Argonne, have produced a revolution in x-ray probing of dense matter during the past decade. These machines use electron-synchrotrons in conjunction with undulator stages to produce 100 psec x-ray pulses with photon energies of several kiloelectronvolts (keV). The applications for x-ray probing of matter are numerous and diverse with experiments in medicine and biology, s… more

1998 Complex Systems Summer School

Description: For the past eleven years a group of institutes, centers, and universities throughout the country have sponsored a summer school in Santa Fe, New Mexico as part of an interdisciplinary effort to promote the understanding of complex systems. The goal of these summer schools is to provide graduate students, postdoctoral fellows and active research scientists with an introduction to the study of complex behavior in mathematical, physical, and living systems. The Center for Nonlinear Studies suppor… more

2009 Pantex Plant Annual Illness and Injury Surveillance

Description: The U.S. Department of Energy’s (DOE) commitment to assuring the health and safety of its workers includes the conduct of epidemiologic surveillance activities that provide an early warning system for health problems among workers. The Illness and Injury Surveillance Program monitors illnesses and health conditions that result in an absence of workdays, occupational injuries and illnesses, and disabilities and deaths among current workers.

The 2013 Cybersecurity Executive Order: Overview and Considerations for Congress

Description: The federal role in cybersecurity has been a topic of discussion and debate for over a decade. Despite significant legislative efforts in the 112th Congress on bills designed to improve the cybersecurity of U.S. critical infrastructure (CI), no legislation on that issue was enacted in that Congress. This report discusses the ramifications of Executive Order 13636, which issued in February 2013 was an attempt to enhance security and resiliency of CI through voluntary, collaborative efforts invo… more

Addressing an Uncertain Future Using Scenario Analysis

Description: The Office of Energy Efficiency and Renewable Energy (EERE) has had a longstanding goal of introducing uncertainty into the analysis it routinely conducts in compliance with the Government Performance and Results Act (GPRA) and for strategic management purposes. The need to introduce some treatment of uncertainty arises both because it would be good general management practice, and because intuitively many of the technologies under development by EERE have a considerable advantage in an uncerta… more

Advanced Safeguards Approaches for New Fast Reactors

Description: This third report in the series reviews possible safeguards approaches for new fast reactors in general, and the ABR in particular. Fast-neutron spectrum reactors have been used since the early 1960s on an experimental and developmental level, generally with fertile blanket fuels to “breed” nuclear fuel such as plutonium. Whether the reactor is designed to breed plutonium, or transmute and “burn” actinides depends mainly on the design of the reactor neutron reflector and the whether the blanket… more

Advanced Safeguards Approaches for New TRU Fuel Fabrication Facilities

Description: This second report in a series of three reviews possible safeguards approaches for the new transuranic (TRU) fuel fabrication processes to be deployed at AFCF – specifically, the ceramic TRU (MOX) fuel fabrication line and the metallic (pyroprocessing) line. The most common TRU fuel has been fuel composed of mixed plutonium and uranium dioxide, referred to as “MOX”. However, under the Advanced Fuel Cycle projects custom-made fuels with higher contents of neptunium, americium, and curium may als… more

Advances in optical materials for large aperture lasers

Description: Lawrence Livermore National Laboratory (LLNL) is using large aperture Nd: glass lasers to investigate the feasibility of inertial confinement fusion. In our experiments high power laser light is focussed onto a small (100 to 500 micron) target containing a deuterium-tritium fuel mixture. During the short (1 to 5 ns) laser pulse the fuel is compressed and heated, resulting in fusion reactions. The generation and control of the powerful laser pulses for these experiments is a challenging scientif… more

Agriculture and the 106th Congress: A Summary of Major Issues

Description: Most congressional interest in agriculture in the 106th Congress was focused on persistent low prices for major commodities and proposals to redress declining farm income. Six emergency farm aid bills were approved, increasing agricultural spending by nearly $27 billion for fiscal years 1999-2001. These bills provided disaster relief along with short term “market loss payments”to farmers to shore up farm income. Some longer term changes also were enacted as part of emergency farm legislation, w… more
