CERN's experiments are global efforts. The 2025 Breakthrough Prize in Fundamental Physics honors over 13,000 researchers whose labors have led to the precise description the Higgs mechanism, the discovery of dozens of new particles, analysis of rare processes and matter-antimatter asymmetry and exploration of nature at the shortest distances and most extreme conditions. breakthroughprize.org/News/91 @CERN

@bhavinhjoshi @CERN See visit.cern ;)

@CERN Is visiting CERN permitted? Asking for a friend.

Here we see parts of the #LHC Beam Loss Monitor (BLM), a key part of the LHC's instrumentation for machine protection and beam optimisation. It produces continuous and reliable measurements of beam losses along the accelerator. Many LHC systems were improved to prepare the accelerator for #LHCRun3 and, soon, the high-luminosity upgrade of the Large Hadron Collider, #HiLumiLHC.

If anyone's wondering why we spend huge efforts to only store a tiny but carefully selected fraction of data that could come from our detector: even that data (+simulated data) is huge! Storing and managing it is yet another challenge

If anyone's wondering what kind of systems I've been busy with during the last few years you may want to tune in here (the speaker is low balling some numbers, the two bigger experiments would produce well over 50 TB/s without a hardware trigger ;) )

@mikefromearth @CERN Have a look at visit.cern

@CERN Can I come visit you CERN?

Here we see the beam dump installed at the Proton Synchrotron (PS) in 2020, when the first synchrotron in CERN’s accelerator family was being outfitted with new, ultra-modern equipment. The new beam dump works differently to those normally used at CERN. It moves to meet the beams, oscillating to block the vacuum chamber so that the particles’ trajectory does not need to be deflected. Find out more: home.cern/news/news/acce…

Physicists: prepare for particles 🫡 Have you ever wondered how the ATLAS experiment prepares for the restart of the #LHC and the start of the data-taking season? Hear from @ATLASExperiment physicists Monica, Andrej, and Catrin about how they  got ready for chapter three of #LHCRun3.  #DidYouKnow that ATLAS is the largest detector ever constructed? At 46 metres long and 25 metres in diameter, its construction defied the limits of existing technology. We seem to have a consensus… Can you name our physicists’ favourite upgrade? Tell us in the comments below. Find out more: atlas.cern

@maxpowertuc @CERN no "tickets" needed for the exhibition, just a brief registration for statistics purposes. Tours for individuals can only be booked on-site (via a local wifi, 1.5h before the start) due to many no-shows in the past

@CERN hey @CERN , can I book tickets online? it says I need to go there for tickets, no booking...

Magnetic fun 🧲 Today’s #PhotoOfTheWeek takes us to the Discovering CERN exhibition at CERN Science Gateway. You may have seen these magnets in your physics classes. #AtCERN, we have a variety of magnets ranging from superconducting to lattice magnets. All the magnets on the #LHC are electromagnets, with the main dipoles generating powerful 8.3–tesla magnetic fields 100 thousand times more powerful than the Earth’s magnetic field. #FunFact: the @ATLASexperiment has the world’s largest superconducting magnet. The ATLAS Barrel Toroid is 5m wide, 25m long, and weighs 100 tonnes. #CERNScienceGateway #PhotoOfTheWeek #ILoveCERN

@TheRealMrRobot3 @cryptonomaly @CERN_JOBS UK *is* a member state: home.cern/about/who-we-a… Then again, you also need to find a university that'd actually aware the PhD in the end (and pay for time beyond the 36 month)

Are you about to pursue a PhD? CERN’s Doctoral Student Programme is a chance to work on your thesis, while spending up to 36 months working for an organisation at the forefront of science. Learn more: cern.ch/b54ha Deadline: 31.07.2023 #CERN Take Part!

@Tristan_duPree @_nikhef Was it stored on a hanger or did you get to unfold it? ;)

Today I was in Nijmegen at the PhD defense committee of Dr. Aggarwal at ⁦Radboud University, first time I wore my gown!👩‍🎓

@Omar_Beny5 @ATLASexperiment D'environ de 1.5 x 10^11 ces jours

@ATLASexperiment Dans 1 paquet combien y a t-il de proton ?

With more proton bunches, comes more particle collisions! These beautiful displays show us a collision event recorded today – when stable beams of 2400 bunches of protons, at the energy of 6.8 TeV per beam, were delivered to ATLAS by the #LHC.

@ShanniaChina @CERN Check CERN Visit Service's page: visit.cern/guided-tours-g…

@CERN May we visit your org in this summer vacation? As a group of university student?

Wandering the immeasurable 🌀 Today’s #PhotoOfTheWeek features the steel sculpture by the Globe of Science and Innovation at #CERN. It is named Wandering the Immeasurable, and it was created by the artist Gayle Hermick. The sculpture, a 15-tonne steel ribbon, symbolises the spread of scientific knowledge. It describes a series of physics, astrophysics and mathematics discoveries, inscripted in their language of origin. 📸 by Jeanneret Guillaume

and we're going.... (in case you didn't know: it's from a public status page: op-webtools.web.cern.ch/vistar/vistars… )

First "stable beams" at high energy for this year coming up - experiment's control room is getting quite crowded

@newolder @ATLASexperiment @CERN check below the linked article

@ragou42 @ATLASexperiment @CERN Thank you. Is there a link to a paper/write up that I may have missed?

In a new search for high-mass particles, physicists at @CERN's ATLAS experiment have investigated several different theoretical models at once. 📽️ Researcher Carsten Burgard explains what was found! Learn more: atlas.cern/Updates/Briefi…

@newolder @ATLASexperiment @CERN Experimentally one can only exclude down to a certain rarity (e.g. due to limited data, i.e., finite number of attempts/collisions) and uncertainties, e.g., concerning contributions of other (known) processes to the data sample

@newolder @ATLASexperiment @CERN The y-axis is related to how frequently one should find events with the supposed new particle, the red line shows what theory predicts for different assumed values of that particle's mass.

@bap47 @CERN The article linked from the tweet does contain a link to the full paper: nature.com/articles/s4146…

CAST-CAPP inches closer to axion #DarkMatter. The CAPP axion haloscope at the CAST experiment has hunted for axions from the Milky Way’s “halo” of dark matter, and has narrowed down the theoretical space in which to look for these hypothetical particles. home.cern/news/news/phys…

Around 6:00 am this morning LHC dumped it's last beams for this year. Hope I can finally get some rest soon now that my days will be less affected by frequent changes of plans during operations (experiments often need to adjust very quickly)

@docm77 So you're saying it'll be a Tuff decision? ;)

The Tuff Golem is really getting more interesting. More info about it came out. It can be stacked, it will become alive but always return to it's original start point, it can pick up items. I might abandon Snifferland...think about it....

A Thirty Laps Around the Sun... What a time scale, just daring to imagine 30y ago that today we could handle all the data collected (several 100s of PB!) seems just crazy
