CERN neutrino project on target

16.08.2005


Scientists at CERN announced the completion of the target assembly for the CERN neutrinos to Gran Sasso project, CNGS. On schedule for start-up in May 2006, CNGS will send a beam of neutrinos through the Earth to the Gran Sasso laboratory 730km away in Italy in a bid to unravel the mysteries of nature’s most elusive particles.



CNGS forms a unique element in the global effort to understand neutrinos, the chameleons of the fundamental particle world. Neutrinos come in three types, or flavours, and have the ability to change between one flavour and another. Neutrinos interact hardly at all with other matter. Trillions of them pass through us every second, and it is precisely their vast numbers that make them a key element in understanding the Universe and its evolution.

The neutrinos leaving CERN are mainly of the muon type. Theory says that by the time they get to Gran Sasso, some of them will have changed into tau neutrinos. Detectors under construction at the Gran Sasso laboratory will measure how many tau neutrinos appear. This is the crucial distinction between CNGS and other long baseline neutrino experiments, which measure the numbers of muon neutrinos at the source and at the detectors to count how many disappear on the way. The measurements are complementary, and both are necessary for a full understanding of the physics of neutrinos. CNGS’s neutrino experiments must be extraordinarily sensitive to detect the small number of tau neutrinos appearing in the beam. Just a few a year will be detected at Gran Sasso.


Having been successfully assembled in the lab, the CNGS target will now be dismantled for installation in its underground target chamber. Installation of the neutrino beam will be complete by the end of the year, and the first beam of neutrinos will leave Geneva, pass about 10km below Florence, and reach Gran Sasso northeast of Rome in May 2006.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

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'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

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....

Im Focus: A quantum walk of photons

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....

Im Focus: Turmoil in sluggish electrons’ existence

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...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

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...
