Evaluating Future US Hydropower Opportunities

Uncertainties, and a lack of confidence regarding issues, such as water availability/storage capacities and operational constraints, can be major obstacles in assessing the range of future opportunities for existing dams, which are certainly substantial. The authors discuss specific challenges facing current infrastructure and water resource data analysis that can inhibit large-scale evaluation of potential hydro development at existing dams. Recent advances in data and tools that may address these challenges are introduced.

The Future Circular Collider: a Summary for the US 2021 Snowmass Process

In this white paper for the 2021 Snowmass process, we give a description of the proposed Future Circular Collider (FCC) project and its physics program. The paper summarizes and updates the discussion submitted to the European Strategy on Particle Physics. After construction of an approximately 90 km tunnel, an electron-positron collider based on established technologies allows world-record instantaneous luminosities at center-of-mass energies from the Z resonance up to tt thresholds, enabling a rich set of fundamental measurements including Higgs couplings determinations at the sub percent level, precision tests of the weak and strong forces, and searches for new particles, including dark matter, both directly and via virtual corrections or mixing. Among other possibilities, the FCC-ee will be able to (i) indirectly discover new particles coupling to the Higgs and/or electroweak bosons up to scales around 7 and 50 TeV, respectively; (ii) perform competitive SUSY tests at the loop level in regions not accessible at the LHC; (iii) study heavy-flavor and tau physics in ultra-rare decays beyond the LHC reach, and (iv) achieve the best potential in direct collider searches for dark matter, sterile neutrinos, and axion-like particles with masses up to around 90 GeV. The tunnel can then be reused for a proton-proton collider, establishing record center-of-mass collision energy, allowing unprecedented reach for direct searches for new particles up to the around 50 TeV scale, and a diverse program of measurements of the Standard Model and Higgs boson, including a precision measurement of the Higgs self-coupling, and conclusively testing weakly-interacting massive particle scenarios of thermal relic dark matter.

TRANSSFORM Workshop Empowering the US manufacturing industry proceedings report

The U.S. Department of Energy (DOE), Office of Energy Efficiency and Renewable Energy, and Advanced Manufacturing Office (AMO) hosted the TRANSSFORM (Transformative, Resilient, Adaptive, Nimble, Sustainable, Smart, Flexible, Optimal, Robust, and Model-based1 – A Bold Vision for the Future of U.S. Manufacturing) Workshop on September 8–10, 2021. The objective of the workshop was to hear from stakeholders about how manufacturing digitalization can improve manufacturing competitiveness and reduce energy consumption and emissions production from U.S. manufacturing, and what research, development, and demonstrations are needed to have the desired impact.
