This report discusses the migration and refugee crisis in Europe, as people flee conflict and poverty in neighboring regions. Many are from the Middle East and Africa; others come from Ukraine, as well as Kosovo and elsewhere in the Western Balkans. Experts have characterized the influxes as mixed migration, defined as flows of different groups of people--such as economic migrants, refugees, asylum-seekers, stateless persons, trafficked persons, and unaccompanied children--who travel the same routes and use the same modes of transportation.

The International Design Study of the Neutrino Factory (IDS-NF) has recently completed its Interim Design Report (IDR), which presents our current baseline design of the neutrino factory. To increase the efficiency and reduce the cost of acceleration, the IDR design uses a linear non-scaling fixed field alternating gradient accelerator (FFAG) for its final acceleration stage. We present the current lattice design of that FFAG, including the main ring plus its injection and extraction systems. We describe parameters for the main ring magnets, kickers, and septa, as well as the power supplies for the kickers. We present a first pass at an engineering layout for the ring and its subsystems.

Gold beams in RHIC revolve more than a billion times over the course of a data acquisition session or store. During operations with these heavy ions the event rates in the detectors decay as the beams diffuse. A primary cause for this beam diffusion is small angle Coloumb scattering of the particles within the bunches. This intra-beam scattering (IBS) is particularly problematic at high energy because the negative mass effect removes the possibility of even approximate thermal equilibrium. Stochastic cooling can combat IBS. A theory of bunched beam cooling was developed in the early eighties and stochastic cooling systems for the SPS and the Tevatron were explored. Cooling for heavy ions in RHIC was also considered.

This report discusses the current state of electric grid cybersecurity, and the interconnected dependency of critical infrastructure with regard to electric sector reliability. It includes discussions of recent developments, cyber and physical security, threats to the grid and supply chain risks, use of artificial intelligence, improvements to grid cybersecurity, recent legislation and other issues for Congress.

This report describes President Trump's current policy toward North Korea and possible options for future U.S. policy. Options include diplomatic engagement, international and U.S. sanction increases, military strikes, destabilization of the North Korean government through intelligence activities and popular resentment, enhanced military cooperation with allies, and additional funding for preventing arms trading and related trade with North Korea.

Report that discusses the Worker Adjustment and Retraining Notification (WARN) Act in brief, especially as related to Congress's renewed interest in the Act due to the current financial crises and recession.

This report discusses the combination of regulations and standards for controlling vessel discharges, which is at issue today and is addressed in legislation in the 114th Congress, the Vessel Incidental Discharge Act.

Report that contains an examination of the current economic circumstances of veteran-owned businesses, available employment assistant programs offered by several federal agencies to assist veterans in their transition from the military to the civilian labor force, and veteran business development programs.

Six dimensional ionization cooling of muons is needed to achieve the necessary luminosity for a muon collider. If that cooling could occur over multiple turns in a closed ring, there would be significant cost savings over a single-pass cooling channel. We report on the status of a cooling ring with achromatic arcs. The achromatic design permits the design to easily switch between a closed ring and a snaking geometry on injection or extraction from the ring. The ring is designed with sufficient space in each superperiod for injection and extraction magnets. We describe the ring's lattice design, performance, and injection/extraction requirements.

This report summarizes article III's standing and congressional suits against the executive branch.

This report seeks to provide an overview of Congress's ability to participate in litigation before Article III courts. The report is limited to a discussion of Congress's participation in litigation as either a plaintiff (e.g., the party initiating the suit alleging some sort of harm or violation of law) or as a third-party intervener (e.g., a party who is seeking to join litigation already initiated by another plaintiff).

Report that looks at three search and seizure cases heard during its October 2012 term.

This report discusses the Trade Promotion Authority program which allows the President to request an expedited procedure for an international trade deal that meets certain requirements. The report answers a variety of frequently asked questions regarding TPA's functions and purpose and Congressional power over it.

This report provides a resource for understanding the current campaigns and elections regulatory structure. It addresses those areas of law and public policy that most directly and routinely affect American campaigns and elections: campaign finance; election administration; election security; redistricting; qualifications and contested elections; and voting rights.

This report addresses the President's general obligation to "take Care that the Laws be faithfully executed." The report then discusses the limited role the judicial branch has traditionally adopted in reviewing discretionary enforcement decisions, including the decision to initiate a criminal prosecution or an administrative enforcement action. The report concludes with a discussion of Congress's authority to restrict executive discretion in the enforcement of federal law.

The objective of this project is to research and develop a thermal energy storage system (operating range 3000C – 450 0C ) based on encapsulated phase change materials (PCM) that can meet the utility-scale base-load concentrated solar power plant requirements at much lower system costs compared to the existing thermal energy storage (TES) concepts. The major focus of this program is to develop suitable encapsulation methods for existing low-cost phase change materials that would provide a cost effective and reliable solution for thermal energy storage to be integrated in solar thermal power plants. This project proposes a TES system concept that will allow for an increase of the capacity factor of the present CSP technologies to 75% or greater and reduce the cost to less than $20/kWht.

The 'EMMA' Non-Scaling Fixed Field Alternating Gradient (ns-FFAG) international project is currently being commissioned at Daresbury Laboratory, UK. This accelerator has been equipped with a number of diagnostic systems to facilitate this. These systems include a novel time-domain-multiplexing BPM system, moveable screen systems, a time-of-flight instrument, Faraday cups, and injection/extraction tomography sections to analyze the single bunch beams. An upgrade still to implement includes the installation of wall current monitors. This paper gives an overview of these systems and shows some data and results from the diagnostics that have contributed to the successful demonstration of a serpentine acceleration by this novel accelerator.

Coherent electron cooling (CEC) has a potential to significantly boost luminosity of high-energy, high-intensity hadron-hadron and electron-hadron colliders. In a CEC system, a hadron beam interacts with a cooling electron beam. A perturbation of the electron density caused by ions is amplified and fed back to the ions to reduce the energy spread and the emittance of the ion beam. To demonstrate the feasibility of CEC we propose a proof-of-principle experiment at RHIC using SRF linac. In this paper, we describe the setup for CeC installed into one of RHIC's interaction regions. We present results of analytical estimates and results of initial simulations of cooling a gold-ion beam at 40 GeV/u energy via CeC. We plan to complete the program in five years. During first two years we will build coherent electron cooler in IP2 of RHIC. In parallel we will develop complete package of computer simulation tools for the start-to-end simulation predicting exact performance of a CeC. The later activity will be the core of Tech X involvement into the project. We will use these tools to predict the performance of our CeC device. The experimental demonstration of the CeC will be undertaken in years three to five of …
