1. Introduction The world power demand will rise to tens of Terawatts in the 21st century. Fossil fuels will be nearly exhausted by 2030, except for coal. Environmental problems may limit the allowable coal consumption. The power generated by tidal wave, wind, hydroelectric, geothermal, biomass, and organic waste together will be inadequate to meet world’s long term energy needs. Fusion power may help to meet energy demand in the future. At LBNL, current fusion program is exploring an effective driver for the purpose, and thus development of beam sources is a critical path. At present, an effective Lithium Aluminosilicate ion source development is in progress to study high energy density physics and ultimately for ignition in fusion sciences. A partial characterization of a Lithium Aluminosilicate source, as fabrication and measurement of current density, life time of beam emission are presented. Materials and Methods Results. DISCUSSION AND IMPLICATIONS Many thanks to my mentors: Dr. Prabir K Roy and Dr. Frank Bieniosek with Lawrence Berkeley National laboratory for providing opportunity and guidance for the experiments. Also, I would like to extend my appreciation to the following individuals who made this program a success and enabled me to have such amazing experience. Dr. Susan Brady, Michael Thibodeau and their CSEE entire staff, Joseph P Krupa (DOE), IISME Staff Shari Liss and her entire staff members ;Sue Kahn (PVHS); Kristen Harrison (IISME) Guillaume Bazouin; Dr. Grant Logan, Dr. Peter Seidl, Mrs. Lynn Heimbucher (LBNL). A special thank you to the S.D. Bechtel, Jr. foundation for support of the Industry Initiatives for Science and Mathematics Education (IISME) fellows. ACKNOWLEDGEMENTS Partial Characterization of Lithium Aluminosilicate Ion Source Kavous Mazaheri, Pinole Valley High School, Pinole, CA Mentors: Prabir K Roy, LBNL &Frank Bieniosek, LBNL Increasing filament current to increase temperature of the source Reading heater filament voltage Beam current signal Controlling diagnostic bias Heater filament current Checking the mounted camera Gathering data Lithium ion beam current density with respect to heater temperature Vacuum chamber containing source & diagnostic (Faraday Cup) Current and voltage are not proportional as they should due to limitation of ions within the source. Richardson plot to measure work function Source preparation At present β-spodumene and β eucryptite Lithium Aluminosilicate test buttons are being tested. The element of the emission has been verified using an EXB filter with a gated camera and YAP scintillator. This beam element verification result was presented elsewhere. Here, current density of a β eucryptite Lithium Aluminosilicate test button has been presented. The beam current density of less than 1 mA/cm 2 was measured. A further increment of current density by varying material calcination and sintering temperatures are in process. The life time of a source is a key characteristics of any ion source. This parameter, life time, is a temperature dependent variable and estimated theoretically. One way to prolong the life time is to change the geometry of the source by increasing its thickness.
