This Phase II STTR will develop a precision balanced optical cross-correlator using engineered nonlinearoptical waveguides. The proposed device will be important for future advances at large scale accelerator facilities by providing a means to achieve long-term sub-femtosecond timing and synchronization of all of a facilitys optical and RF sub-systems over fiber optic links. Statement of how this ...

Organic chemicals comprise the dominant fraction of particulates found in atmospheric aerosols, and the largest proportions of these are secondary products formed in the atmosphere from oxidation of volatile organic compounds. Often these chemical transformations result from complex pathways involving species from different sources. To understand these processes, we need to be able to trace the ...

State of the art yttria stabilized zirconia (YSZ) based thermal barrier coatings (TBCs) are typically limited to maximum use temperatures of 1200-1300C. A thermal barrier coating (TBC) with a 1500C temperature capability would be a major gas turbine materials breakthrough. New coatings with a 200C temperature advantage can be used by the gas turbine industry to significantly increase turbine effi ...

Proposed designs for a Future Circular Collider (FCC) to collide protons with a center-of-mass energy of 100 TeV call for dipoles with fields up to 20 Tesla (T). This is significantly beyond the present technology and requires using High Temperature Superconductors (HTS). The recent Particle Physics Project Prioritization Panel (P5), organized by the U.S. Department of Energy (DOE), strongly supp ...

The majority of Big Data applications have been built around the MapReduce paradigm. Despite the popularity of MapReduce, there are several obstacles to applying it for some commercial and scientific use-cases. This includes the requirement to load data into specialized file systems, like HDFS, in addition to long intermediate data shuffle and sorting phases involving storage, which will impose si ...

Additive Manufacturing (AM), where three-dimensional (3D) objects are created from a digital model by depositing and fusing successive layers of material, provides the ability to produce low-volume, customized products with complex geometries relatively quickly at a moderate cost. However, AM processes sometimes fail to produce acceptable parts, due to either geometric in- accuracy (e.g., shrinkag ...

Experiments planned to better constrain the value of the neutron electric dipole moment will test the standard model of physics and thereby contribute to DOEs mission to understand the fundamental forces and particles of nature as manifested in nuclear matter. These experiments take place in an interaction region where the magnetic and electric fields must be precisely controlled. It is a challeng ...

For advanced gas turbines where turbine inlet temperature reaches 2650F and beyond, the current state-of-the-art thermal barrier coating (TBC) systems are not adequate to provide the needed protection for the metallic components of the turbine engine. Thus there is a need to develop new chemistries for TBC systems, consisting of bond coat and top coat, with enhanced durability. We propose to modi ...

The DOE NNSA Defense Nuclear Nonproliferation missions include monitoring, assaying, and identifying Special Nuclear Materials (SNM). Facilities commonly contain large quantities of additional radioactive materials causing high-background count rates that obscure the important SNM measurements using ordinary spectroscopic radiation detectors.This program seeks to develop a portable segmented germa ...

Due to enormous growth of Internet traffic, the scale and responsiveness required for delivering applications to end users can be cost-effectively achieved by the increased adoption of cloud-based, virtualized services built by widespread use of compute, storage, and network virtualization. Therefore, IT infrastructures of enterprises, Research and Education (R&E) networks (e.g., DOE ESnet), and c ...
