(Image: US Department of State, Bureau of Oceans and International Environmental and Scientific Affairs) CERN and the US government have released a joint statement concerning future planning for large research infrastructures, advanced scientific computing and open science. The Joint Statement of Intent was signed in Washington DC in April by CERN Director-General, Fabiola Gianotti, and Principal Deputy US Chief Technology Officer, Deirdre Mulligan, of the White House Office of Science and Technology (pictured). Acknowledging their longstanding partnership in nuclear and particle physics, CERN and the US intend to enhance collaboration in planning activities for large-scale, resource-intensive facilities with the goal of providing a susta…
- Computer Security: The better generationComputer Security: The better generation To all those fine folks out there who are interested in computer security, who take care of the secrecy of their passwords and other credentials, who protect their laptops and smartphone adequately with up-to-date operating systems and antivirus software, and who apply due diligence when developing and running their IT services and/or control systems, I would issue just two words: THANK YOU! Thank you for reading our articles. Thank you for showing an interest in privacy and security. Thank you for wanting to learn more about this. Thank you, because you are the generation who can get it right. Or better, as my generation of 1971 didn't screw everything up. What’s gone before Look, for example, at an ancient telephone – the one with a rotary dial. Back then, fear of being spied on was minimal, and only an issue if you annoyed your country. Today, we all carry small spying devices around that collect all our personal information and pass it on.…
- NA64 uses the high-energy SPS muon beam to search for dark matterNA64 uses the high-energy SPS muon beam to search for dark matter The NA64 experiment started operations at CERN’s SPS North Area in 2016. Its aim is to search for unknown particles from a hypothetical “dark sector”. For these searches, NA64 directs an electron beam onto a fixed target. Researchers then look for unknown dark sector particles produced by collisions between the beam’s electrons and the target’s atomic nuclei. Recently, the NA64 team started using a muon beam from the SPS to search for new particles that interact predominantly with muons – heavier versions of the electron – and could explain simultaneously the long-standing puzzle of the muon’s anomalous magnetic moment and the dark-matter (DM) problem. Their first results were accepted in the journal Physical Review Letters on 8 April. In this paper, the NA64 collaboration sets new limits on the available parameter space – the window where the researchers could find a hypothetical dark boson Z’ coupling only to muons a…
- CERN 70th anniversary exhibition at Geneva AirportCERN 70th anniversary exhibition at Geneva Airport To honour its 70 years of contributions to scientific knowledge, technological innovation and international collaboration, CERN has put together a rich and diverse programme, at CERN and across its Member States, Associate Member States and beyond. This programme includes exhibitions, the first of which can now be visited at Geneva Airport as part of a collaboration between the two organisations. Inaugurated on 2 May, the exhibition’s three components will occupy the wall leading to the security check before entering the departure lounge, the “Panorama” terrace and the international terminal until autumn 2024. Find out more on the “CERN and its neighbours” website. anschaef Wed, 05/15/2024 - 12:09 Byline Zoe Nikolaidou Publication Date Wed, 05/15/2024 - 12:07
- HiLumi News: The HL-LHC’s cold powering system successfully passed the testsHiLumi News: The HL-LHC’s cold powering system successfully passed the tests The HL-LHC cold powering system undergoing tests in SM18. (Image: CERN) If you’re an avid follower of High-Luminosity LHC (HL-LHC) news, you will no doubt already have heard about “the python”, the new superconducting link developed at CERN. It is a component of the new cold powering system that will power the HL-LHC inner triplet magnets, which will focus proton beams more tightly around the ATLAS and CMS collision points. This new system is packed with novel superconducting technologies: MgB2 superconducting cables, twisted together to form a compact bundle of about 9 centimetres in diameter, are inserted into a 22-centimetre-diameter flexible cryostat, with vacuum insulation and flowing helium gas. The MgB2 cables operate in the helium gas at temperatures from about 4.5 K (-268.7 °C) to 20 K (-253.2 °C). The REBCO high-temperature superconducting cables then transfer the current from 20 K…
