Muon Colliders have unique technical and physics advantages and disadvantages when compared with both hadron and electron machines. They should thus be regarded as complementary. Parameters are given of 4 TeV and 0.5 TeV high luminosity µ + µ − colliders, and of a 0.5 TeV lower luminosity demonstration machine. We discuss the various systems in such muon(More)
The goal of the Robust Affordable Next Generation Energy Storage System (RANGE)-BASF program is to provide an alternative solution for the energy storage media that powers electric vehicles other than the existing Li-ion battery. With the use of a rare-earth-free metal hydride (MH) as the active negative electrode material, together with a core-shell type(More)
KOH-based electrolytes with different salt additives were investigated to reduce their corrosive nature toward Mg/Ni metal hydride alloys used as negative electrodes in nickel metal hydride (Ni/MH) batteries. Alkaline metal halide salts and oxyacid salts were studied as additives to the traditional KOH electrolyte with concentrations varying from 0.005 M to(More)

In this study we compared the electrochemical pressure-concentration-temperature (EPCT) method with the gaseous phase pressure-concentration-temperature (PCT) method and demonstrated the differences between the two. Experimentally, this was done by electrochemically charging/discharging the electrodes of four different metal hydride (MH) alloys. The results(More)

The third-integer coupling resonance at ν(x)-2ν(z)=ℓ, known as the Walkinshaw resonance, is important in high-power accelerators. We find that, when the betatron tunes ramp through a Walkinshaw resonance the fractional emittance growth (FEG) is a universal function of the effective resonance strength: G(1,-2,ℓ)√[ε(xi)]|Δ(ν(x)-2ν(z))/Δn|(-1/2), where(More)
Effects of preparative parameters on the structure and performance of Ca–La metal oxide catalysts for oil transesterification Abstract The effects of preparative parameters on the surface basicity, composition, and transesterification activities of several Ca-La metal oxide catalysts were investigated. Four different preparation methods:(More)
Synergetic effects in multi-phased AB 2 Laves-phase-based metal hydride (MH) alloys enable the access of high hydrogen storage secondary phases, despite the lower absorption/desorption kinetics found in nickel/metal hydride (Ni/MH) batteries. Alloy design strategies to further tune the electrochemical properties of these secondary phases include the use of(More)

Advisor Date ! ! ! ii! ACKNOWLEDGEMENTS I owe a great deal of gratitude to my country " Kingdom of Saudi Arabia " , King Abdullah bin Abdulaziz Al Saud, and Saudi Arabian Cultural Mission in USA for believing and giving me the opportunity to accomplish my dream. Also, I would never have been able to finish my PhD dissertation without the guidance of my(More)
The muon collider would extend limitations of the e + e ? colliders and provide new physics potentials with a possible discovery of the heavy Higgs bosons. At the maximum energy of 2 TeV the projected luminosity is of the order of 10 35 cm ?2 s ?1. The colliding + ? bunches have to be focused to a very small transverse size of 2.8 m which is accomplished by(More)
