St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics.
This device is a further step forward to controlled nuclear fusion. The device will help researchers to get precise information about energy distribution of hot plasma electrons inside the tokamac – the most promising current prototype of the future thermonuclear reactor.
The new diagnostics system is based on the original laser construction designed by scientists at the Open Joint-Stock Company “Control Modules. Laser Beam Engineering and Technology” (MULTITEX) and the Ioffe Physical & Engineering Institute, Russian Academy of Sciences. It allows them - figuratively speaking - to apply a thermometer to plasma burning at temperatures in the millions of degrees – the substance tortiled by magnetic fields, where heavy hydrogen tritium interacts to liberate tremendous amounts of energy.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
