Конечно, в профиле Европейской организации по ядерным исследованиям CERN (@cern) в Instagram вы не увидите фотографии сталкивающихся элементарных частиц. Но зато вы всегда будете в курсе последних научных открытий и проектов и узнаете, как будут модернизировать Большой адронный коллайдер в течение ближайших двух лет. Иногда в профиле публикуются исторические фотографии, которые рассказывают о том, как создавался известнейший проект в области ядерной физики.
Посмотреть эту публикацию в Instagram Our #PhotoOfTheWeek shows a new mini-accelerator being developed here at CERN. This version will be used for cultural-heritage projects. — CERN and #INFN are collaborating on a project called MACHINA, which stands for «Movable Accelerator for Cultural Heritage In-situ Non-destructive Analysis». INFN, and in particular the Laboratory for Nuclear Techniques for Cultural Heritage and the Environment (LABEC) in #Florence, has more than 35 years of experience in accelerator analysis of cultural-heritage artworks. Collaborating with INFN-LABEC thus allows compact proton-accelerator technology developed at CERN to be optimised and used in cultural-heritage projects. — #MACHINA is under development and the first analysis of a real art object is scheduled to be conducted in 2020. — #CERN #Accelerators #instascience #sciencephotography #physics #particlephysics #engineering Публикация от CERN (@cern) 23 Янв 2019 в 8:10 PST
Посмотреть эту публикацию в Instagram The GBAR experiment’s electromagnetic «Buffer Gas Trap» #PhotoOfTheWeek The @GBAR_experiment, which plans to test the free fall of ultra-cold antihydrogen atoms, requires a very large number of positrons (electron antiparticles) to synthesize its neutral and charged antiatoms. These are produced at a rate of some ten million per second using a linear electron accelerator. However, these positrons still need to be cooled and accumulated in order to make them usable. This is the role of the «Buffer Gas Trap». It is a Penning-Malmerg trap (electromagnetic trap for charged particles) in which there is gas (carbon dioxide and nitrogen) at very low pressure for positrons to lose their energy by collision with thegas molecules. During the operation, some of the positrons are lost by annihilation with the electrons of the gas molecules, but the remaining positrons can be more easily compressed and transferred into a second Penning-Malmberg trap, nicknamed «RIKEN Trap». In this second trap with a higher magnetic field, a high vacuum is used to store positrons permanently. Transfers from the Buffer Gas Trap to the RIKEN Trap are repeated until the desired number of positrons is reached, about ten billion.

It was transported to CERN in June 1973 while a second (spare) condenser was being completed in Berlin. In the picture the clearances between the radial rotor blades and the specially shaped stator blades mounted on the circumference of the housing were being checked. #1973 #particlephysics #sciencephotography #engineering #physics Публикация от CERN (@cern) 25 Окт 2018 в 6:55 PDT
Посмотреть эту публикацию в Instagram #PhotoOfTheWeek • This photo shows a scientist working on a module of the new Inner Tracking System (ITS) of @alice_experiment, the ALICE ITS Inner Barrel Stave. It will be installed in the heart of the #experiment in 2020 and will track particles produced in the #collisions. • The Inner Layers of the ITS are made of 48 of this modules, which are called «staves», as they are placed as the staves of a barrel, in cylindrical concentric layers around the particle #beam line, and centered with respect to the interaction point. • Find out more about the ALICE experiment: http://cern.ch/go/ALICE •?

Посмотреть эту публикацию в Instagram 1971: First ever proton collisions • #ThrowbackThursday #TBT • On 27 January 1971, Kjell Johnsen, who led the construction team which built the Intersecting Storage Rings (ISR), announced that the first ever interactions from colliding protons had been recorded. On the left are Franco Bonaudi, who was responsible for the civil engineering and Dirk Neet, who later took charge of ISR operations. • Find out more: http://cern.ch/go/J6cG (link in bio) #CERNalumni #ScienceHistory #SciencePhotography #FirstTime #ParticlePhysics #Physics #CERN Публикация от CERN (@cern) 13 Сен 2018 в 7:30 PDT

The surface treatment of copper is one of the most important competences needed to achieve the required performance in attaining very low vacuum. • The High Intensity and Energy (HIE) upgrade of the #ISOLDE linear accelerator will allow to collide beams of isotopes into targets at higher energies, in order to explore fundamental questions concerning different elements on the planet. • Meet ISOLDE: http://cern.ch/go/jrm9 (link in profile) •?

Посмотреть эту публикацию в Instagram The #neutrino castles are being prepared for their testing phase. • Measuring 12 m x 12 m x 12 m, the two #ProtoDUNE neutrino detectors seem massive… But in fact, they are small: they are only representative slices of the much larger Deep Underground Neutrino Experiment (DUNE), whose detectors will be 20 times larger. • #DUNE, an international experiment hosted by @fermilab in the United States, will live deep underground and trap neutrinos: tiny fundamental particles that rarely interact with #matter. • Currently under construction at #CERN, the two prototypes will soon be cooled down to allow their testing, using a beamline at CERN’s SPS accelerator complex. • Find out more: http://cern.ch/go/CV8C (link in bio) •?
