Bus Rapid Transit: Projects Improve Transit Service and Can Contribute to Economic Development
A letter report issued by the Government Accountability Office with an abstract that begins "U.S. bus rapid transit (BRT) projects we reviewed include features that distinguished BRT from standard bus service and improved riders’ experience. However, few of the projects (5 of 20) used dedicated or semi-dedicated lanes— a feature commonly associated with BRT and included in international systems to reduce travel time and attract riders. Project sponsors and planners explained that decisions on which features to incorporate into BRT projects were influenced by costs, community needs, and the ability to phase in additional features. For example, one project sponsor explained that well-lighted shelters with security cameras and real-time information displays were included to increase passengers’ sense of safety in the evening. Project sponsors told us they plan to incorporate additional features such as off-board fare collection over time."

Calculation of Eddy Currents In the CTH Vacuum Vessel and Coil Frame
Knowledge of eddy currents in the vacuum vessel walls and nearby conducting support structures can significantly contribute to the accuracy of Magnetohydrodynamics (MHD) equilibrium reconstruction in toroidal plasmas. Moreover, the magnetic fields produced by the eddy currents could generate error fields that may give rise to islands at rational surfaces or cause field lines to become chaotic. In the Compact Toroidal Hybrid (CTH) device (R0 = 0.75 m, a = 0.29 m, B ≤ 0.7 T), the primary driver of the eddy currents during the plasma discharge is the changing flux of the ohmic heating transformer. Electromagnetic simulations are used to calculate eddy current paths and profile in the vacuum vessel and in the coil frame pieces with known time dependent currents in the ohmic heating coils. MAXWELL and SPARK codes were used for the Electromagnetic modeling and simulation. MAXWELL code was used for detailed 3D finite-element analysis of the eddy currents in the structures. SPARK code was used to calculate the eddy currents in the structures as modeled with shell/surface elements, with each element representing a current loop. In both cases current filaments representing the eddy currents were prepared for input into VMEC code for MHD equilibrium reconstruction of …

Cerium Doped LSO/LYSO Crystal Development for future High Energy Physics Experiments
Because of their high stopping power and fast and bright scintillation, cerium doped LSO and LYSO crystals have attracted a broad interest in the physics community pursuing precision electromagnetic calorimeter for future high energy physics experiments. Their excellent radiation hardness against gamma-rays, neutrons and charged hadrons also makes them a preferred material for calorimeters to be operated in a severe radiation environment, such as the HL-LHC. An effort was made at SIPAT to grow 25 X{sub 0} (28 cm) long LYSO crystals for high energy physics applications. In this paper, the optical and scintillation properties and its radiation hardness against gamma-ray irradiations up to 1 Mrad are presented for the first 2.5 X 2.5 X 28 cm LYSO sample. An absorption band was found at the seed end of this sample and three other 20 cm long samples, which was traced back to a bad seed crystal used in the corresponding crystal growth process. Significant progresses in optical and scintillation properties were achieved for large size LYSO crystals after eliminating this absorption band.

Characterization of Disruption Halo Currents in the National Spherical Torus Experiment
This paper describes the general characteristics of disruptions halo currents in the National Spherical Torus Experiment [M. Ono, et al. Nuclear Fusion 40, 557 (2000)]. The commonly observed types of vertical motion and resulting halo current patterns are described, and it is shown that plasma discharges developing between components can facilitate halo current flow. The halo current fractions and toroidal peaking factors at various locations in the device are presented. The maximum product of these two metrics for localized halo current measurements is always significantly less than the worst-case expectations from conventional aspect ratio tokamaks (which are typically written in terms of the total halo current). The halo current fraction and impulse is often largest in cases with the fastest plasma current quenches and highest quench rates. The effective duration of the halo current pulse is comparable to or shorter than the plasma current quench time. The largest halo currents have tended to occur in lower β and lower elongation plasmas. The sign of the poloidal halo current is reversed when the toroidal field direction is reversed.

Chemical, Biological, Radiological, and Nuclear Risk Assessments: DHS Should Establish More Specific Guidance for Their Use
A letter report issued by the Government Accountability Office with an abstract that begins "Since 2004, DHS’s use of its CBRN risk assessments to inform its CBRN response plans has varied, from directly influencing information in the plans to not being used at all. DHS guidance states that response planning and resource decisions should be informed by risk information. GAO’s analysis showed that DHS used its CBRN risk assessments to directly inform 2 of 12 CBRN response plans GAO identified because planners considered the risk assessments to be more accurate than earlier DHS planning assumptions. For another 7 of the 12 plans, DHS officials said that the assessments indirectly informed the plans by providing background information prior to plan development. However, GAO could not independently verify this because DHS officials could not document how the risk assessments influenced the information contained in the plans. GAO’s analysis found general consistency between the risk assessments and the plans. For the remaining 3 plans, DHS officials did not use the risk assessments to inform the plans; for 2 of the 3 plans DHS officials told GAO they were not aware of the assessments. DHS officials also noted that there was no departmental guidance …

China and Proliferation of Weapons of Mass Destruction and Missiles: Policy Issues
Congress has long been concerned about whether U.S. policy advances the national interest in reducing the role of the People's Republic of China (PRC) in the proliferation of weapons of mass destruction (WMD) and missiles that could deliver them. Recipients of China's technology reportedly include Pakistan and countries said by the State Department to have supported terrorism, such as Iran. This CRS Report, updated as warranted, discusses the security problem of China's role in weapons proliferation and issues related to the U.S. policy response since the mid-1990s.

A Class Of Generalized Kapchinskij-Vladimirskij Solutions And Associated Envelope Equations For High-intensity Charged Particle Beams
A class of generalized Kapchinskij-Vladimirskij solutions of the nonlinear Vlasov-Maxwell equations and the associated envelope equations for high-intensity beams in a periodic lattice is derived. It includes the classical Kapchinskij-Vladimirskij solution as a special case. For a given lattice, the distribution functions and the envelope equations are specified by eight free parameters. The class of solutions derived captures a wider range of dynamical envelope behavior for high-intensity beams, and thus provides a new theoretical tool to investigate the dynamics of high-intensity beams.
