Semiconductor Technology for Particle Accelerators

29.04.2013
Corporate Technology (CT), Siemens global research department, has developed a new accelerator technology in cooperation with one of its strategic partners, the Russian research center Skol­kovo, which is located near Moscow.

This technology, which is expected to lower the cost of particle accelerators, is featured in the current issue of the research magazine Pictures of the Future.



Other partners involved in the project are the Budker Institute for Nuclear Physics in Novosibirsk, the Institute for Theoretical and Experimental Physics in Moscow, Goethe University in Frankfurt am Main and the Gesellschaft für Schwerionenforschung (Society for Heavy Ion Research) in Darmstadt.

High energy beams of neutrons, protons and other ions are used, in medical radiation therapies and in the materials processing industry. The high voltages required to accelerate these particles are produced by high-frequency generators. Using new semiconductor components, Siemens researchers can significantly increase the efficiency of the generators. This new technology requires less space and is less expensive to produce and operate.

People often associate particle accelerators with large laboratories such as CERN and DESY. In fact, most of the around 30,000 facilities in use worldwide are located in clinics and industry. At the heart of an accelerator is a high-frequency generator that produces high voltages at several hundred megahertz. They are based on electron tubes that require a sophisticated high voltage electrical supply and reach a maximum efficiency of 60 percent.

In order to achieve a higher efficiency the CT researchers are using transistors based on the semiconductor silicon carbide. These components work at very high frequencies, cope with high power outputs and offer up to 70 percent efficiency. One such transistor has an output of several kilowatts and is easily a hundred times smaller than a comparable electron tube. Now, modules made up of several transistors can achieve a power output of 160 kilowatts at a frequency of 324 megahertz. These values are roughly what medical and industrial applications require. The next step is to produce units with an output of around three megawatts suitable for scientific applications.

The researchers are also using semiconductor technology to develop inexpensive standardized control cabinets for the drive units of accelerators. It will also be possible to combine these cabinets according to the needs of a given situation. A prototype should be ready in 2013.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
