In this talk, plasma applications to (1) high energy particle acceleration and (2) hydrogen source will be introduced. For particle acceleration, plasma waves are excited for accelerating particles. Because the electric field strength of plasma waves will be about 1000 times stronger than that in the large accelerator such as “LHC” (Large Hadron Collider) located in CERN, Switzerland, which has about 37 km circumference in order to push up the electron collision energy to 8 TeV, the plasma wave accelerator will be 1/1000 of LHC in size. For plasma wave accelerators the wave-guide for microwave transmission line is a key acceleration tool and the maximum electric field strength inside the cavity can reach 100 MV/m. For the hydrogen source, which can be used for fuel cells to produce electricity (to learn more about electricity and electric power, visit "Throw The Switch" on the Smithsonian website Powering a Generation of Change.), it is usually produced by chemical processes in large plants. However, such processes produce large amount of dirty gases and have storage and distribution problems. To produce hydrogen cleanly, we have developed the plasma discharge technology to directly decompose hydrocarbon fuels to hydrogen gas and carbon particles. The experimental results of decomposition of hydrocarbon gases into hydrogen gas and carbon particles using plasma discharge technology will be presented. |
