More that 52% of the U.S. highway congestion in urban areas is a direct result of highway incidents. Federal and State transportation authorities are searching for quick, low-cost and efficient highway incident detection and warning systems. Several solutions have been proposed but none could meet the requirements of transportation authorities. Central Signal, funded by federal agencies, has done ...

Emc2's proposal provided to DOT in response to SBIR Research topic 07-PH1 on "Design Optimization for Soft Crack Arrestors" focuses on the development of key material property data needed to design "soft crack arrestors". This testing will be done over a range of temperatures to cover extreme conditions for future pipeline designs. It is also essential to develop this data at the loading rates t ...

Dielectric structures driven by wakefields or external radio frequency (RF) are presently being studied intensively as a promising technique for next generation linear colliders. This project will develop dielectric loaded accelerating structures that can be adjusted in frequency using a bias electric field. The method proposed here is inexpensive and easy to implement without affecting beam quali ...

The single bunch beam breakup (BBU) instability is a potentially serious limitation on the performance of advanced accelerators, particularly those based on the wakefield principle. Development of mitigation techniques for BBU requires both experiment and high performance simulation tools. This project will study three representative high performance wakefield devices using new diagnostics. An adv ...

The design trend in normal-conducting high gradient accelerating structures is to move toward higher frequencies. The same is true for other microwave applications like radar or communications. This project will develop a new high power radio frequency (RF) source that covers the frequency spectrum from 20-30 GHz. It will evaluate a prototype power extraction structure incorporating advanced low l ...

As the dimensions of accelerating structures become smaller, or as beam intensities become higher, the transverse wakefields driven by the beam become quite large, even for a slight misalignment of the beam from the geometric axis. These deflection modes can cause inter-bunch beam breakup and intra-bunch head-tail instabilities along the beam path. This project will design a cylindrical dielectric ...

This project will develop a diamond-based accelerating structure that can sustain an accelerating gradient larger than 600 MV/m, which would significantly exceed the limits of conventional accelerating structures. Multipacting will be suppressed by dehydrogenation of the diamond surface. In Phase I, a cylindrical diamond-based dielectric loaded accelerator structure will be designed, developed, an ...

The detection of charged particles through Cherenkov radiation has been a powerful technique in particle, nuclear, and beam physics. Use of a dielectric radiator with engineered dispersive properties permits more information about the radiating particle to be obtained than from a simple linear medium. This project will numerically model, construct, and test Cherenkov radiators that are based on th ...

Commercialization of Proton Exchange Membrane (PEM) fuel cells requires low-cost components, materials, and manufacturing processes. Specifically, the manufacture of the fuel cell¿s bipolar plates utilizes methods that are slow, expensive, and inappropriate for some advanced flow field designs. It is desirable that new manufacturing technologies be developed that enable advanced designs at high v ...

The International Linear Collider (ILC) requires microscale-smooth RF superconducting cavities fabricated from niobium. The task of polishing the cavities currently involves the use of toxic electrolytes that include hydrofluoric acid. It is desirable to find new methods of surface finishing that use environmentally benign electrolytes for increased worker safety. This project will develop and dem ...
