Superconducting Radio Frequency (SRF) structures used for particle accelerators typically operate between 4 – 2 K, i-e- cryogenic temperatures, and are sensitive to microphonics that create length oscillations in the accelerating structures- To keep the SRF cavities on resonance under the influence of distortions in the SRF cavities caused by microphonics, RF power above what is required for acc ...

The next generation nuclear physics accelerator facility, the Electron Ion Collider (EIC), will accelerate and collide spin polarized electrons and ions focused to an unprecedented density at their point of collision- To achieve the desired electron/ion density at the focal point, random velocity variations in the ions will be reduced using the technique of electron cooling- In this technique, the ...

There is a fundamental need for a high-performance computing (HPC) approach to computational electromagnetics (CEM) modeling tools suitable for designing and optimizing the next generation photonics devices- The dramatic grown of telecommunications bandwidth requirements is fueling demand for advanced manufacturing methods of next-generation devices capable of incorporating new phenomena such as p ...

There is a lack of cost-effective and easy-to-use tools and services for complex data streams which is characterized by multi-dimensional features including large data volumes, variety, velocity and veracity that are commonly referred to as BigData- BigData creates a scalability challenge for environmental system solutions that use traditional relational databases to perform organization, retrieva ...

Mesa Photonics proposes to develop signal processing for timing used in X-ray free electron oscillators- This diagnostic will be able to provide sub-femtosecond relative timing between X-ray pulses and optical pulses at the pulse repetition rates of X-ray free electron laser oscillators- In this SBIR project, Mesa Photonics will develop signal processing for measuring the time arrival between opti ...

Solid oxide fuel cells (SOFCs) require robust, hermetic seals that can prevent both fuel leakage and direct mixing of fuel and air- The seal materials should be electrical insulators and should be chemically and mechanically stable in high temperature reactive environments (e-g-, moist reducing and/or oxidizing conditions)- The seals should exhibit no deleterious interfacial reactions with other c ...

Increasing the volumetric capacity of hydrogen storage is critical to bringing fuel-cell powered vehicles to market- High-pressure, compressed-hydrogen tanks are large, heavy, and expensive- High-pressure compression is also costly, energy-intensive, potentially hazardous, and is made even more challenging due to the non-idealities of hydrogen gas at elevated pressures- Physical adsorption of hydr ...

By 2025, 1.8 billion people will be living in places with severe water scarcity and two-thirds of the global population will encounter some degree of water stress. If warming continues at the current pace, by 2030 half of the world’s population will experience severe water stress (Runte 2016). The demands are strong; the restraints, on the other hand, come from (1) high capital investment for eq ...

Radio-frequency cavities are at the heart of particle accelerators used for nuclear and high-energy physics research, medical treatment, pollution control, clean energy production, development of new materials, and national security. The most advanced accelerators utilize cavities that are made from superconducting materials. However, the performance of these cavities is reaching a fundamental lim ...

Accelerators are necessary for the fundamental study of matter and its origins. A critical component of accelerators are the niobium superconducting radio frequency (SRF) cavities, which are used to accelerate the particles. Because of the significant number of niobium SRF cavities required for each accelerator, innovative manufacturing techniques are needed to reduce fabrication costs and to ensu ...
