Radio-frequency (RF) breakdowns is an important barrier to obtaining higher field gradients in modern accelerators. Unfortunately, there are presently no simulation tools that allow understanding and quantitative estimation of the damage produced by RF breakdown in realistic accelerating structures and RF components. This project will develop a new computational tool for the analysis of RF breakdo ...

Cementing is an integral part of well construction, providing the seal, protection, and support for the casing to maintain barriers that isolate the well.Wells can experience integrity failure due to structural instability in cemented regions due to subsidence and compaction caused by reservoir depletion over the lifetime of the well.Increased knowledge of cement placement, integrity, and conditio ...

"Li-ion batteries have a major downside which is their potential to initiate fires, escalate to thermal runaway increasing the violence, and to possibly explode.Traditional fire extinguishing agents either perform poorly or are impractical on these high-energy fires.Two innovations, in combination, are proposed for research and development.Pyrotechnic aerosol extinguishing agents will be proven hi ...

We propose to develop the know-how necessary to utilize additive manufacturing (AM) to fabricate hardware having the material and structural characteristics needed to meet exacting high-vacuum requirements of scientific R&D. Additive manufacturing (AM) offers the potential to realize the production of monolithic components while significantly reducing investments of resources including time, effor ...

Fusion science has immediate need for fabrication of high-vacuum complex 3D structures. We propose to develop the know-how necessary to use metal additive manufacturing (AM) to produce structures (such as chambers) possessing vacuum and structural characteristics that meet this need. Traditional methods for producing high-vacuum components typically require the manufacturing of multiple parts, sub ...

High-power klystrons are expensive critical components of proposed high-energy particle accelerators such as the International Linear Collider. Spurious oscillations in traditional pencil-beam klystrons have been a major cause of poor performance and tube failure, requiring expensive retrofitting to correct. Although sheet-beam klystrons have recently been proposed as a less expensive and more r ...

78140S Strong radio-frequency electric fields in high-power components used in colliders can induce a resonant cascade of particles near internal surfaces (called multipacting) that can lead to surface breakdown and device failure, in some cases limiting the power than can be handled to a fraction of the design specification. Existing tools available to analyze this phenomenon have limited accu ...

Extensive research (Ukraine) has shown that high strength continuous fibers of basalt can be produced. These fibers are inexpensive and have exceptionally high strength, stiffness and corrosion resistance. Basalt is a naturally occurring volcanic mineral, consisting a variety concentration of oxides. The product envisioned is a low-cost, corrosion resistant replacement for steel bar in reinforc ...

75336-A broad category of experiments in astro-particle and high energy physics requires the construction of ultra-high-purity and ultra-low-radioactive-background, cubic-meter-scale vessels to be used as containers for ionization and scintillation media. Double-beta decay experiments, solar neutrino experiments, and dark matter searches would all benefit from this technology. Plastics are among ...
