Title: Final progress report for "To continue to explore the energy frontier with the ATLAS detector"

Abstract

We are trying to understand the origin of our universe, the gap between the current theory: the Standard Model (SM) and the very beginning; the question is what led to our universe as we see today, and what are the conditions that might have led to the SM.

  • The Boston University (BU) group is playing key roles across the ATLAS experiment: in detector operations, the online trigger, the upgrade, computing, and physics analysis. Our team has been critical to the maintenance and operations of the muon system since its installation. During Run 1 we led the muon trigger group and that responsibility continues into Run 2. BU maintains and operates the ATLAS Northeast Tier 2 computing center. We are actively engaged in the analysis of ATLAS data from Run 1 and Run 2. Physics analyses we have contributed to include Standard Model measurements (W and Z cross sections,more » t\bar{t} differential cross sections, WWW^* production), evidence for the Higgs decaying to \tau^+\tau^-, and searches for new phenomena (technicolor, Z' and W', vector-like quarks, dark matter).« less
  • A state-of-the-art gamma-ray facility has been constructed for use at the ATLAS facility of the Argonne National Laboratory. It consists of a 50-element central BGO Sum-Energy/Multiplicity Spectrometer surrounded by 12 high purity. Compton-suppressed Ge Spectrometers. A number of electronics modules needed for an efficient use of the facility have also been designed and constructed. The full device is now operational and meets or exceeds all its design specifications.
  • The characteristics of sites in Indiana and Illinois which are being investigated as potential sites for compressed air energy storage power plants are documented. These characteristics include geological considerations, economic factors, and environmental considerations. Extensive data are presented for 14 specific sites and a relative rating on the desirability of each site is derived. (LCL)
  • Badger Basin Field was discovered in 1931. Production is principally from low-permeability fractured sandstones of the Upper Cretaceous Frontier Formation. Though many wells initially produced at about 100 barrels of oil per day or more, they now produce at stripper rates. Only about 12% of the estimated 25 million barrels of oil originally in-place will be produced from the twenty-two attempted vertical completions. The goal of this joint project between Sierra Energy Company (Sierra) and the US Department of Energy (DOE) was to recover addition reserves at economic rates through the use of 3D seismic and horizontal drilling and completingmore » techniques.« less
  • Our EFRC was founded with the vision of creating a broadly collaborative and synergistic program that would lead to major breakthroughs in the molecular-level understanding of the critical interfacial charge separation and charge transfer (CST) processes that underpin the function of candidate materials for organic photovoltaic (OPV) and electrical-energy-storage (EES) applications. Research in these energy contexts shares an imposing challenge: How can we understand charge separation and transfer mechanisms in the presence of immense materials complexity that spans multiple length scales? To address this challenge, our 50-member Center undertook a total of 28 coordinated research projects aimed at unraveling themore » CST mechanisms that occur at interfaces in these nanostructured materials. This rigorous multi-year study of CST interfaces has greatly illuminated our understanding of early-timescale processes (e.g., exciton generation and dissociation dynamics at OPV heterojunctions; control of Li+-ion charging kinetics by surface chemistry) occurring in the immediate vicinity of interfaces. Program outcomes included: training of 72 graduate student and postdoctoral energy researchers at 5 institutions and spanning 7 academic disciplines in science and engineering; publication of 94 peer-reviewed journal articles; and dissemination of research outcomes via 340 conference, poster and other presentations. Major scientific outcomes included: implementation of a hierarchical strategy for understanding the electronic communication mechanisms and ultimate fate of charge carriers in bulk heterojunction OPV materials; systematic investigation of ion-coupled electron transfer processes in model Li-ion battery electrode/electrolyte systems; and the development and implementation of 14 unique technologies and instrumentation capabilities to aid in probing sub-ensemble charge separation and transfer mechanisms.« less
