1971: The world’s first hadron collider 📸⠀ -⠀ #TBT #ThrowbackThursday ⠀ -⠀ This picture shows the Intersecting Storage Rings (ISR), a former particle accelerator at #CERN. In fact, the ISR was the world’s first hadron collider, having provided both proton–proton and proton–antiproton collisions. The ISR was built to look for particles like quarks and W bosons, which had not been observed then, as well as exotic particles like magnetic monopoles.⠀ -⠀ The ISR shut down in 1984 and CERN’s focus shifted to the planned Large Electron–Positron Collider. Today, the ISR tunnel is used for storage and magnet work.

Our #PhotoOfTheWeek shows visitors at the @ATLASexperiment during the #CERNOpenDays. ⠀ -⠀ ATLAS is currently preparing for the future. The detector has been opened up in order to undergo maintenance and upgrades for the era of the High-Luminosity LHC. The HL-LHC, which will begin operating in a few years, will greatly increase the rate of particle collisions, creating more opportunities for physics discoveries.

🤖 This is the ROCLA, one of the robots used to transport the #LHC magnets from one place to another. ⠀ -⠀ Operating the ROCLA was one of the activities our guests could participate in during the #CERNOpenDays. ⠀ -⠀ #DidYouKnow that 75,000 visitors discovered hundreds of activities on nine CERN sites this weekend? 🎉

2008/2013: CERN Open Days 📸⠀ -⠀ #TBT #ThrowbackThursday ⠀ -⠀ Take a look back at the previous #CERNOpenDays. We will open our doors once again this coming weekend!⠀ -⠀ If you’re going to be around, share your experience on social media using the hashtag #CERNOpenDays. We look forward to seeing what you're up to here at CERN.⠀ -⠀ Please note that not everyone will be able to go underground, but many visit points on the surface are never accessible other than during the CERN Open Days. Don't miss out on the chance to see these treasure troves of science.

No, this is not the Incredible Hulk's hot tub… ⠀ -⠀ This photo shows the shielding being assembled for the Super Proton Synchrotron's new beam dump, which will absorb beams of particles whose flight through the SPS needs to be terminated.⠀ -⠀ The new object is nine metres long, with several hundred tonnes of shielding, and will be installed around the beam line of the SPS. It will be the longest single component of the SPS, which is the second-largest machine in CERN’s accelerator complex.

1967: In the heart of the CERN Data Centre 💻 ⠀ -⠀ #TBT #ThrowbackThursday ⠀ -⠀ In order to analyse the data from the experiments, CERN has built the largest computer centre in Europe. The CERN Data Centre is the heart of CERN’s entire scientific, administrative and computing infrastructure.⠀ -⠀ The #LHC experiments produce over 50 petabytes of data per year and around 25 petabytes are produced per year from other experiments at CERN. Archiving the vast quantities of data is an essential function at CERN; most of the data collected in CERN’s data centre is highly valuable and needs to be preserved and stored for future generations of physicists.

Our #PhotoOfTheWeek shows the first component of the High-Luminosity LHC installed in the LHC. 🎉⠀ -⠀ This component, known as a TANB, is an absorber designed to protect the machine. The High-Luminosity LHC, which will be commissioned in 2026, will boost the performance of the current accelerator by increasing the number of collisions in the experiments. Luminosity is a crucial indicator of an accelerator’s performance. The higher the luminosity, the higher the probability of new #discoveries. ⠀ -⠀ Increasing the number of collisions requires reinforcing the protection of the LHC’s equipment. The aim of the TANB absorber is to protect the accelerator equipment by stopping particles produced in collisions in the @LHCbexperiment. From 2021 onwards, LHCb will record five times more collisions than before.

No, this isn't Mace Windu's lightsaber!⠀ ⠀ It is the trace left by a beam of negative hydrogen (H−) ions ionising a gas inside Linac4, CERN's newest accelerator. The gas is injected into the accelerator to mitigate repulsion between particles with the same charge.⠀ ⠀ Linac4 is a linear accelerator designed to boost negative hydrogen ions to high energies. It is scheduled to become the source of proton beams for the Large Hadron Collider (LHC) after the current long shutdown. Once accelerated to 160 MeV, the particles will be sent to the Proton Synchrotron Booster and continue their journey through the accelerator complex. Linac4 is a key element of the upgrade of CERN’s accelerators for the High-Luminosity LHC.

1976: Horst Kremmlin working at ISOLDE 🕵️⠀ -⠀ #TBT #ThrowbackThursday ⠀ -⠀ This picture shows a member of one of the ISOLDE experiments working on mercury isotopes using laser spectroscopy. Isotopes are variants of a particular chemical element which have the same number of protons but different numbers of neutrons in each atom. Kremmling’s group performed the first determination of the nuclear properties of short-lived isotopes by optical spectroscopy.⠀ -⠀ ISOLDE studies the properties of atomic nuclei, with applications in fundamental studies, astrophysics, material and life sciences.

📸 Our #PhotoOfTheWeek shows the Large Hadron Collider ( #LHC ) tunnel during the second long shutdown (LS2). ⠀ -⠀ #DidYouKnow that work for the High-Luminosity LHC is currently in progress 100 metres underground? This next generation LHC, which will begin operation in 2026, will reach luminosities five to ten times higher than its predecessor. This increased number of collisions will increase the chances of observing rare processes.
