Chromaticity of the lattice and beam stability in energy-recovery linacs (open access)

Chromaticity of the lattice and beam stability in energy-recovery linacs

Energy recovery linacs (ERLs) are an emerging generation of accelerators promising to revolutionize the fields of high-energy physics and photon sciences. These accelerators combine the advantages of linear accelerators with that of storage rings, and hold the promise of delivering electron beams of unprecedented power and quality. Use of superconducting radio-frequency (SRF) cavities converts ERLs into nearly perfect 'perpetuum mobile' accelerators, wherein the beam is accelerated to a desirable energy, used, and then gives the energy back to the RF field. One potential weakness of these devices is transverse beam break-up instability that could severely limit the available beam current. In this paper, I present a method of suppressing these dangerous effects using a natural phenomenon in the accelerators, viz., the chromaticity of the transverse motion.

Climate Change: A Coordinated Strategy Could Focus Federal Geoengineering Research and Inform Governance Efforts (open access)

Climate Change: A Coordinated Strategy Could Focus Federal Geoengineering Research and Inform Governance Efforts

A letter report issued by the Government Accountability Office with an abstract that begins "Policymakers have raised questions about geoengineering--large-scale deliberate interventions in the earth's climate system to diminish climate change or its impacts--and its role in a broader strategy of mitigating and adapting to climate change. Most geoengineering proposals fall into two categories: carbon dioxide removal (CDR), which would remove carbon dioxide (CO2) from the atmosphere, and solar radiation management (SRM), which would offset temperature increases by reflecting sunlight back into space. GAO was asked to examine (1) the state of geoengineering science, (2) federal involvement in geoengineering, and (3) the views of experts and federal officials about the extent to which federal laws and international agreements apply to geoengineering, and any governance challenges. GAO examined relevant scientific and policy studies, relevant domestic laws and international agreements, analyzed agency data describing relevant research for fiscal years 2009 and 2010, and interviewed federal officials and selected recognized experts in the field."

Combating Gangs: Federal Agencies Have Implemented a Central American Gang Strategy, but Could Strengthen Oversight and Measurement of Efforts (open access)

Combating Gangs: Federal Agencies Have Implemented a Central American Gang Strategy, but Could Strengthen Oversight and Measurement of Efforts

A letter report issued by the Government Accountability Office with an abstract that begins "Thousands of gang members in the United States belong to gangs such as MS-13 and 18th Street that are also active in Central American countries. Federal entities with responsibilities for addressing Central American gangs include the National Security Council (NSC); the Departments of Homeland Security (DHS), Justice (DOJ), and State; and the U.S. Agency for International Development (USAID). GAO was asked to review federal efforts to combat transnational gangs. This report addresses (1) the extent to which the federal government has developed a strategy to combat these gangs, and (2) how federal agencies have implemented the strategy and other programs to combat these gangs, coordinated their actions, and assessed their results. GAO examined federal agencies' antigang plans, resources, and measures; interviewed federal, state, and local officials in seven localities representing varying population sizes and geographic regions; and interviewed U.S. and foreign officials in El Salvador and Guatemala where U.S. agencies have implemented antigang programs. The results of these interviews are not generalizable."

Combined Ideal and Kinetic Effects on Reversed Shear Alfven Eigenmodes (open access)

Combined Ideal and Kinetic Effects on Reversed Shear Alfven Eigenmodes

A theory of Reversed Shear Alfven Eigenmodes (RSAEs) is developed for reversed magnetic field shear plasmas when the safety factor minimum, qmin, is at or above a rational value. The modes we study are known sometimes as either the bottom of the frequency sweep or the down sweeping RSAEs. We show that the ideal MHD theory is not compatible with the eigenmode solution in the reversed shear plasma with qmin above integer values. Corrected by special analytic FLR condition MHD dispersion of these modes nevertheless can be developed. Large radial scale part of the analytic RSAE solution can be obtained from ideal MHD and expressed in terms of the Legendre functions. The kinetic equation with FLR effects for the eigenmode is solved numerically and agrees with the analytic solutions. Properties of RSAEs and their potential implications for plasma diagnostics are discussed.

Commercial Aviation: Program Aimed at High-Risk Parent Abductors Could Aid in Preventing Abductions (open access)

Commercial Aviation: Program Aimed at High-Risk Parent Abductors Could Aid in Preventing Abductions

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2000, the annual number of new international parental child abduction cases reported to the Department of State--many of which likely involved air travel--has nearly tripled. Such abductions occur when a parent, family member, or person acting on behalf thereof, takes a child to another country in violation of the custodial parent's or guardian's rights. Once a child is abducted, the laws, policies, and procedures of the foreign country determine the child's return. Thus, preventing such abductions can help keep parents and children from being separated for a long period or indefinitely. As requested, this report addresses (1) the policies and measures airlines, federal agencies, and others have to prevent international parental child abductions on airline flights and (2) options federal agencies, airlines, and others could consider for helping prevent such abductions on airline flights, as well as the advantages and limitations of those options. To perform this work, GAO reviewed applicable laws and policies, interviewed government officials, and surveyed airlines and nonprofit associations."

Commercial Spectrum: Plans and Actions to Meet Future Needs, Including Continued Use of Auctions (open access)

Commercial Spectrum: Plans and Actions to Meet Future Needs, Including Continued Use of Auctions

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1994, FCC has made over 520 megahertz (a measure of quantity) of spectrum available for new uses, such as wireless broadband, through a process that can be lengthy. Because most of the usable spectrum in the United States has been allocated to existing uses, FCC must change its rules to move spectrum from an existing use to a new use, a process known as repurposing spectrum. Yet, this process can be lengthy—from 7 to 15 years for the six repurposings that GAO reviewed. Four factors contribute to the time it takes FCC to repurpose spectrum: the regulatory nature of the process, which to some extent is guided by statute; opposition of incumbent users, who could be required to vacate spectrum; coordination challenges between FCC and the National Telecommunications and Information Administration (NTIA), which oversees federal agencies’ use of spectrum, on the repurposing of federal spectrum for commercial use; and concerns about interference from users of spectrum in adjacent bands of spectrum. FCC has identified voluntary approaches that it thinks could speed the process, but these approaches generally require congressional approval and face some stakeholder opposition."
