AbstractThe far-term goal of this research is in development and design of accelerator able to provide & gt;1 GeV/m for electrons. This goal will be reached by usage of Si micro-structure made with Lithographic technology common in micro-circuit fabrication. To avoid heat damage of micro-structure, the laser focus swept along the accelerator micro- structure by a special electro-optical device in accordance with the instant beam position inside the structure (A.Mikhailichenko, Laser Driven Linear Collider, EPAC08, Genoa, Italy 2008, WEPP155, Proceeding, pp. 2850-2852; http://accelconf.web.cern.ch/AccelConf/e08/papers/wepp155.pdf). In this project we optimized the dimensions of micro-structure in a view of real technology available at mostly Nano-factories located around. Numerical 3D calculations of swept laser beam illuminated micro-structure will be performed. Design will be ready for fabrication in a Second phase, if awarded. International Linear Collider (ILC) with its ~30 MeV/m, identified by the ~30 km total length. It is hard to believe, that such gradient will be acceptable for a multi-TeV collider which is required for answering the question about our Universe history and future. For the estimated cost of ILC ~$15B, the cost of unit length comes to 0.5M$/m. From the other hand with ability to reach the gradient 10GeV/m the length of collider will be ~100 m only. So even if the cost of equipment will have the same linear cost (500k$/m-good price for the laser component equipment) the total spending will be 50M$ only. This impressive cost shrinkage is a moving wheel for this Project. We believe that the best way to go is to use micro-and nano-technology, which is booming now as a request of microelectronics, mainly. Fraction of a micrometer is a typical scale for the processor technology. One should agree that if the scale of accelerating structure is small-less energy required filling it with the electromagnetic radiation to reach desirable accelerating electric field. Special method of excitation of this tiny structure makes the gradient 10GeV/m feasible. Demonstration of this is a content of this Project. At the accomplishment of Stage I, fully optimized accelerator with micro-structure will be developed and ready for fabrication and test at Phase II if awarded.Commercial Applications and Other Benefits: Successful realization of our Plan will open a possibility for fabrication of microchip-size accelerators able generation the gamma rays-flux of variable energy. Accelerator gradient ~10GeV/m opens a possibility for economical design of high energy collider electron/positron, muon/muon and even pion/pion one.
