Optical Biosensors, Compact Particle Accelerators and the ITER
Kamil Boratay Alıcı
We continue with brief explanation of a compact solid state accelerating structure based on resonant surface modes. The structure is composed of SiC on Si layers separated to create subwavelength acceleration channel. Surface wave modes are numerically and experimentally characterized with angle resolved microscopy and tunable CO2 laser. Existing superluminuos mode paves the way to table top charged particle acceleration. Ultrashort electron bunches can be characterized optically by using the same structure. Last part of the talk deals with ITER project. In year 1951, in the Idaho State of USA it has been proven that an experimental generating reactor (EBR-I) can generate electricity by using nuclear energy. 3 years after, Russia added 5MW, and 2 years after that UK added 50 MW nuclear energy plant to their grids. Today, as of January 2013, there are 437 nuclear power plants in the world generating 372 GW of power. In 15 countries 68 nuclear power plants are under construction to generate 65 GW of power. According to the 2012 data nuclear energy has 4% share and follows oil (33%), coal (30%), natural gas (24%) and hydroelectricity (7%).
International thermonuclear experimental reactor (ITER) is the most advanced experiment that aims to demonstrate technological and scientific feasibility of fusion energy. The quality of the reactor is planned to exceed 10 that is the ratio of generated fusion power to input power. The machine is designed to produce 500 MW and will be the first tokamak that generates net fusion energy. ITER will be a technology testing platform for commercial fusion reactors. ITER will be followed by fusion based electricity plant (DEMO) whose theoretical design will be completed in 2017 and is planned to add to the grid 2000-4000 MW power in 2040.
