Ceramic Matrix Composites (CMCs) can provide excellent high temperature performance in a wide range of applications (e.g., jet engines). However, designing and manufacturing components from CMCs continues to represent a challenge to industry. AltaSim Technologies is currently developing design tools for subject matter experts at large corporations with significant computational resources. Small to ...

Detectors and radiation monitors for future high energy and nuclear physics experiments must be able to withstand radiation environments several orders of magnitude harsher than those of any current device. At present, most radiation detectors are based on silicon technology, however, the practical radiation hardness limit of silicon falls far short of requirements in future high ener ...

Ethylene and propylene are the primary feedstocks for the manufacture of polyethylene and polypropylene, respectively. These olefins represent a major component of the polymer manufacturing cost. Consequently, there is significant economic benefit in minimizing losses of unreacted olefin from the process. Some olefin loss is a result of the need to remove paraffin from the polymerization reactor ...

Synchrotron-based science has had a great scientific impact and will continue to have great impact going forward. In spite of the large investment in the 3rd generation light sources, most beam lines do not preserve the sources phase profile or brightness all the way to the sample. For these high brightness light sources, errors are almost completely due to distortion in the front-end optics cau ...

Multipactor discharges in dielectric accelerating structures are a major limitation on the performance of this otherwise very promising technology for future high energy physics machines and other applications. We will experimentally study a new approach, using a proper external solenoid field, to completely suppress multipactor. This approach has been theoretically studied and verified in a 3-D n ...

Fast electronic tuning of SC cavities is a critical issue for optimized rf power distribution for accelerators. The overall goal of the program is to develop an L-band externally-controlled fast ferroelectric tuner for controlling the coupling of superconducting RF cavities for the future linear colliders. Recently proposed planar tuner design requires new elements to be developed made of an impro ...

Current energy storage devices have energy densities that are barely sufficient for low cost electric-vehicles and rely on lithium ion batteries that use flammable, unsafe, liquid electrolytes. However, in order to replace liquid electrolyes in lithium batteries for hybrid electric power train systems, solid polymer electrolytes, which have the advantages of safety and flexibility, must attain con ...

U.S. Department of Energy, Office of Basic Energy Sciences (BES) under Topic 11 ADVANCED SOURCES FOR ACCELERATOR FACILITIES Subtopic (b), Undulator Radiation Sources, is seeking superconducting undulators that can generate tunable (i.e. variable field) mono- chromatic x-ray beams in the 2-30 keV photon energy range from medium-energy (2-3 GeV) synchrotrons. These requireme ...

This proposal is submitted in response to the SBIR/STTR High Energy Physics Solicitation Topic 30(a). High-Field Superconductor and Superconducting Magnet Technologies for High Energy Particle Colliders, (a) High-Field Superconducting Wire Technologies for Magnets. The need is for strands that can operate in the 15/17T or higher regime, and have deff values of 30 m or less, with non-Cu Jc values a ...

There is high demand for tunable X-ray undulators in modern synchrotron light sources. While PrFeB based magnets are most suitable for cryogenically operated permanent magnet undulators (CPMU), there are no development efforts or a manufacturing base for PrFeB magnets. We will develop PrFeB based magnets of higher remanence and better coercivity (at 77 K) than current neodymium based magnets for ...
