A letter report issued by the Government Accountability Office with an abstract that begins "The total number of aliens detained per year by the Department of Homeland Security's (DHS) U.S. Immigration and Customs Enforcement (ICE) increased from about 95,000 in fiscal year 2001 to 283,000 in 2006. The care and treatment of these detained aliens is a significant challenge to ICE. GAO was asked to review ICE's implementation of its detention standards for aliens in its custody. GAO reviewed (1) detention facilities' compliance with ICE's detention standards, (2) ICE's compliance review process, and (3) how detainee complaints regarding conditions of confinement are handled. To conduct its work, GAO reviewed DHS documents, interviewed program officials, and visited 23 detention facilities of varying size, type, and geographic location."

In the International Linear Collider (ILC) [1] the colliding beams must be focused to the nanometer size in order to reach the desired luminosity. The method of Weak Antisolenoid is used for the compensation of the effect of the Detector Solenoid on the beam size [2], [3]. The studies of this method require the computer simulation of the charged particle's kinematics in the arbitrarily distributed solenoidal, dipole, quadrupole and higher multipole fields. We suggest the mathematical algorithm that allows to optimize parameters of antisolenoid for different configurations of Final Focus magnets and to compensate parasitic effects of the Detector Solenoid on the beam.

This procedure provides guidelines and techniques for analyzing and trending data using statistical methods for Lawrence Berkeley National Laboratory (LBNL). This procedure outlines the steps used in data analysis and trending. It includes guidelines for performing data analysis and for monitoring (or controlling) processes using performance indicators. This procedure is used when trending and analyzing item characteristics and reliability, process implementation, and other quality-related information to identify items, services, activities, and processes needing improvement, in accordance with 10 CFR Part 830, Subpart A, U.S. Department of Energy (DOE) Order 414.1C, and University of California (UC) Assurance Plan for LBNL. Trend codes, outlined in Attachment 4, are assigned to issues at the time of initiation and entry into the Corrective Action Tracking System (CATS) database in accordance with LBNL/PUB-5519 (1), Issues Management Program Manual. Throughout this procedure, the term performance is used to encompass all aspects of performance including quality, timeliness, efficiency, effectiveness, and reliability. Data analysis tools are appropriate whenever quantitative information describing the performance of an item, service, or process can be obtained.

The LCLS project databases provide key nomenclature information while integrating many engineering and physics processes in the building of an accelerator. Starting with the elements existing in the beam line optics files, the engineers add non-beam-line elements, and controls engineers assign ''Formal Device Names'' to these elements. Inventory, power supplies, racks, crates and cable plants are databases that are being integrated into the project database. This approach replaces individual spreadsheets and/or integrates standalone existing institutional databases.

In this volume (I), all P-wave measurements are presented that were performed in Borehole C4993 at the Waste Treatment Plant (WTP) with T-Rex as the seismic source and the Lawrence Berkeley National Laboratory (LBNL) 3-D wireline geophone as the at-depth borehole receiver. P-wave measurements were performed over the depth range of 370 to 1400 ft, typically in 10-ft intervals. However, in some interbeds, 5-ft depth intervals were used, while below about 1200 ft, depth intervals of 20 ft were used. Compression (P) waves were generated by moving the base plate of T-Rex for a given number of cycles at a fixed frequency as discussed in Section 2. This process was repeated so that signal averaging in the time domain was performed using 3 to about 15 averages, with 5 averages typically used. In addition to the LBNL 3-D geophone, called the lower receiver herein, a 3-D geophone from Redpath Geophysics was fixed at a depth of 22 ft in Borehole C4993, and a 3-D geophone from the University of Texas was embedded near the borehole at about 1.5 ft below the ground surface. This volume is organized into 12 sections as follows: Section 1: Introduction, Section 2: Explanation of Terminology, …

The ILC positron damping ring comprises hundreds of meters of wiggler sections, where many more photons than in the arcs are emitted, and with the smallest beampipe aperture of the ring. A significant electron-cloud density can therefore be accumulated via photo-emission and via beam-induced multipacting. In field-free regions the electron-cloud build up may be suppressed by adding weak solenoid fields, but the electron cloud remaining in the wigglers as well as in the arc dipole magnets can still drive single-bunch and multi-bunch beam instabilities. This paper studies the electron-cloud formation in an ILC wiggler section for various scenarios, as well as its character, and possible mitigation schemes.

In the E-167 plasma wakefield acceleration experiment, electrons with an initial energy of 42GeV are accelerated in a meter-scale lithium plasma. Particles are leaving plasma with a large energy spread. To determine the spectrum of the accelerated particles, a two-plane spectrometer has been set up.

The National Nuclear Security Administration (NNSA) Ground-Based Nuclear Explosion Monitoring Research and Engineering (GNEM R&E) Program at LLNL has made significant progress enhancing the process of deriving seismic calibrations and performing scientific integration, analysis, and information management with software automation tools. Several achievements in schema design, data visualization, synthesis, and analysis were completed this year. Our tool efforts address the problematic issues of very large datasets and varied formats encountered during seismic calibration research. As data volumes have increased, scientific information management issues such as data quality assessment, ontology mapping, and metadata collection that are essential for production and validation of derived calibrations have negatively impacted researchers abilities to produce products. New information management and analysis tools have resulted in demonstrated gains in efficiency of producing scientific data products and improved accuracy of derived seismic calibrations. Significant software engineering and development efforts have produced an object-oriented framework that provides database centric coordination between scientific tools, users, and data. Nearly a half billion parameters, signals, measurements, and metadata entries are all stored in a relational database accessed by an extensive object-oriented multi-technology software framework that includes elements of stored procedures, real-time transactional database triggers and constraints, as well as coupled Java …

Although elements of the information and intelligence fusion function were conducted prior to 9/11, often at state police criminal intelligence bureaus, the events of 9/11 provided the primary catalyst for the formal establishment of more than 40 state, local, and regional fusion centers across the country. This report contains information on potential risks of fusion centers, evolution of the concept of fusion centers, characteristics of state and regional fusion centers, challenges and potential options as relating to fusion centers for Congress, and related information.

The development of an electron cloud in the vacuum chambers of high intensity positron and proton storage rings may limit the machine performances by inducing beam instabilities, beam emittance increase, beam loss, vacuum pressure increases and increased heat load on the vacuum chamber wall. The electron multipacting is a kind of geometric resonance phenomenon and thus is sensitive to the geometric parameters such as the aperture of the beam pipe, beam shape and beam bunch fill pattern, etc. This paper discusses the geometric effects on the electron cloud build-up in a beam chamber and examples are given for different beams and accelerators.
