Could today's technology suffice for engineering advanced-fuel, magnetic-fusion power plants, thus making fusion development primarily a physics problem? Such a path would almost certainly cost far less than the present D-T development program, which is driven by daunting engineering challenges as well as physics questions. Advanced fusion fuels, in(More)
The design of a 1000 MWe D-He3 tokamak fusion power plant, Apollo-L3, is presented. The reactor operates in the first plasma stability regime and relies on both direct and thermal conversion of the thermonuclear energy to electricity. The synchrotron energy is converted directly to electricity via rectennas at 80% efficiency and the thermal energy is(More)
In 2003, the Stanford Synchrotron Radiation Laboratory (SSRL) has upgraded its storage ring to a 3 rd generation storage ring (SPEAR3). SPEAR3 is deigned to operate at 500 mA stored beam current and 3 GeV energy. The 234-meter circumference SPEAR3 ring utilizes 60-cm-thick concrete lateral walls, 30-cm-thick concrete roof, as well as 60-cm or 90-cm-thick(More)
Neutronics and activation calculations have been performed for the FIRE design with different first wall design options. Modest values of nuclear heating occur in the machine components. Magnet insulators that have radiation tolerance to 150 MGy should be used. The operational schedule allows for decay of short-lived radionuclides between pulses resulting(More)
Dose control and measurement plans for the SPEAR3 Booster and storage ring have taken place during the SPEAR3 commissioning. The initial commissioning period (SPEAR3 start-up) covered the time period from the was characterized with frequent injection and significantly higher losses. In comparison, the scientific program period was characterized with more(More)
A new method to estimate remanent dose rates, to be used with the Monte Carlo code FLUKA, was benchmarked against measurements from an experiment that was performed at the CERN-EU high-energy reference field facility. An extensive collection of samples of different materials were placed downstream of, and laterally to, a copper target, intercepting a(More)
