The International Committee for Future Accelerators (ICFA) announced at a scientific conference in Beijing that the planned International Linear Collider (ILC) is to be realized in superconducting technology. This decision is of great importance for DESY and its international partners, since they developed this technology together and successfully tested it at the TESLA Test Facility (TTF) in Hamburg. The ILC is the next major project of particle physics. No decision has yet been taken on the realization and site of the facility. As the next step, particle physicists will now join forces to develop the technical design of the project as rapidly as possible.
The ICFA committee, which represents particle physicists worldwide, thus decided between two possible technologies that have been developed in America, Asia and Europe during the past 12 years. The two technologies differ mainly in their accelerating structures, the so-called cavities. These accelerate the particles to high energies before they collide. The cavities can be normal conducting and are then operated at room temperature (“warm” version), or superconducting with an operating temperature close to absolute zero (“cold” version).
“With this technology decision, worldwide particle physics has made a major step forward toward the future – a step in which the true success really is the international agreement,” commented Albrecht Wagner, Chairman of the DESY Directorate, today at a press conference of the International Institute of High Energy Physics (IHEP) in Beijing. “Without the worldwide endorsement of one of the two viable technologies, realization of the ILC project would be unthinkable. Of course, DESY takes note of the technology decision with special pleasure. For what was a technological vision ten years ago has now become reality. This is the result of the joint efforts of DESY and its international partners – the TESLA Collaboration, which decisively improved the performance of superconducting accelerating cavities.”

Strathclyde-led research develops world's highest gain high-power laser amplifier
29.05.2017 | University of Strathclyde
The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
