A press conference to mark the occasion will be held at the press room of Geneva International Airport at 9:00 CEST on 25 August, and journalists will have the opportunity to visit the AMS detector and the aircraft. Those wishing to attend to the visit should contact the CERN press office by 12:00 CEST on Monday 23 August at the latest, providing their nationality, date of birth and passport or identity card number. This document must also be presented before the visit. Please note that only the people who have registered will be able to go on the apron to visit the AMS detector and the aircraft. Journalists who would like to see the arrival of the AMS detector at Kennedy Space Center on 26 August are invited to apply until 19 August. Details are available from ESA: http://www.esa.int/esaCP/SEM0R65OJCG_index_0.html.
AMS will examine fundamental issues about matter and the origin and structure of the Universe directly from space. Its main scientific target is the search for dark matter and antimatter, in a programme that is complementary to that of the Large Hadron Collider.
Last February the AMS detector travelled from CERN to the European Space Research and Technology Centre (ESTEC) in Noordwijk (Netherlands) for testing to certify its readiness for travel into space. Following the completion of the testing, the AMS collaboration decided to return the detector to CERN for final modifications. In particular, the detector’s superconducting magnet was replaced by the permanent magnet from the AMS-01 prototype, which had already flown into space in 1998. The reason for the decision was that the operational lifetime of the superconducting magnet would have been limited to three years, because there is no way of refilling the magnet with liquid helium, necessary to maintain the magnet’s superconductivity, on board the space station. The permanent magnet, on the other hand, will now allow the experiment to remain operational for the entire lifetime of the ISS.
Following its return to CERN, the AMS detector was therefore reconfigured with the permanent magnet before being tested with CERN particle beams. The tests were used to validate and calibrate the new configuration before the detector leaves Europe for the last time.
“The entire AMS collaboration is delighted by this departure, because it marks a crucial milestone for the experiment. We are getting close to the space shuttle launch and the moment when our detector will finally be installed on board the ISS,” explained Professor Sam Ting, Nobel laureate and spokesman for the experiment. “The detector’s construction phase is now finished and we are eager for the data collection phase to begin.”
“The launch of AMS detector is very timely,” added Roberto Petronzio, President of the Italian National Institute for Nuclear Physics. “Today we are well aware of our ignorance of Universe’s most abundant constituents and we still challenge the puzzle of matter-antimatter asymmetry. Furthermore, recent results from the Pamela experiment suggest scenarios for important discoveries for AMS. The experiment stems from a large international collaboration joining the effort of major European funding agencies with the US and China.”
Upon arrival at the Kennedy Space Center, AMS will be installed in a clean room for a few more tests. A few weeks later, the detector will be moved to the space shuttle. NASA is planning the last flight of the space shuttle programme, which will carry AMS into space, for the end of February 2011.
Once docked to the ISS, AMS will search for antimatter and dark matter by measuring cosmic rays. Data collected in space by AMS will be transmitted to Houston (USA) and on to CERN’s Prévessin site, where the detector control centre will be located, and to a number of regional physics analysis centres set up by the collaborating institutes.
"We are proud that this detector, which will play such an important role, will be flown from Geneva International Airport to the Kennedy Space Center in Florida," said Robert Deillon, General Manager of Geneva International Airport.Contact
2.The AMS detector components were produced by an international team, with substantial contributions from CERN Member States (Germany, France, Italy, Spain, Portugal and Switzerland), and from China (Taipei) and the United States. The detector was assembled at CERN, with the assistance of the Laboratory’s technical services.

Breaking: the first light from two neutron stars merging
17.10.2017 | American Association for the Advancement of Science
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
