[Breakthrough @brkthroughprize]

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. https://t.co/OSDzo6jMHF @CERN

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

[ATLAS Experiment @ATLASexperiment]

New milestone for the ATLAS experiment at @CERN! We've hit over 1 exabyte (that's 1 billion billion bytes) of real and simulated data worldwide, managed using @RucioData.

That's a whole lotta data! #datascience🌌💾

[ragou42 @ragou42]

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 ;) )

[CERN openlab @CERNopenlab]

Today's CERN openlab Summer Student Lecture is about ‘DAQ-filtering data from 50 TB/s to 1GB/s’.

Hear from Flavio Pisani (CERN) how @CERN safely moves the physically relevant part of the data produced by the #LHC to long-term storage.

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.

@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

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)

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

and we're going.... (in case you didn't know: it's from a public status page: https://t.co/RbrQetNbob )

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

[ragou42 @ragou42]

@newolder @ATLASexperiment @CERN check below the linked article

[ragou42 @ragou42]

@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

[ragou42 @ragou42]

@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.

[ragou42 @ragou42]

@bap47 @CERN The article linked from the tweet does contain a link to the full paper: https://t.co/zEJ18RFCtr

[ragou42 @ragou42]

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)

[ragou42 @ragou42]

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

[ragou42 @ragou42]

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

[ATLAS Experiment @ATLASexperiment]

The ATLAS Collaboration at @CERN is turning 30! 🎂

On 1 Oct 1992, thirty years ago today, we submitted our letter of intent to the LHC Experiments Committee - marking the start of a new era of scientific discovery. Check out our timeline to learn more!
