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 ...

MSP is introducing in this proposal a practical approach to a family of cascade impactors capable of real-time measurement of the size-distributed mass concentration of particles in the atmosphere. Further, because of the high sensitivity of the proposed mass transducers, these impactors will also provide nearly instantaneous information about the influence of water vapor on the size distribution ...

Photocathodes with spin-polarized electron emission are used in physics research. Current photocathodes offer high polarization, but low total currents, and have limited lifetime. Research involving these polarized electrons would be more productive if a higher electron current were provided. This program seeks to increase the delivered polarized electron current from the photocathodes by adding i ...

For several decades photomultiplier tubes (PMTs) have been the main technology for sensitive and low noise detection of photons in many high energy physics experiments. However, compared to solid-state photodetectors, PMTs are bulky, fragile, expensive, and need to be shielded from high magnetic fields and high pressures, which severely limit their application for future DOE projects. Hence, th ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at the Stanford Linear Accelerator Center (SLAC). Future systems, such as the International Linear Collider (ILC), will require a polarized electron beam intensity at least 20 times greater than produced by strained GaAs, which is used in the current gene ...
