Do you see the particles flying through our detector representation @nikhef.bsky.social?! #KM3NeT #Neutrino #Detector #Particle #Physics #Astrophysics #Outreach

After a wonderful 50th anniversary year in 2025, the management and staff of the National Institute for Subatomic Physics Nikhef wish you a prosperous 2026. www.nikhef.nl/en/news/nikh...

AI is rapidly becoming an indispensable technology in particle and astroparticle physics. To accelerate scientific discovery, Nikhef is establishing a dedicated AI R&D group to enable more, faster and better science across all its research programmes. www.nikhef.nl/en/news/arti...

... en daarna op bezoek bij @nikhef.bsky.social (nederlands instituut voor deeltjesfysica), waar o.a. het world wide web mede is 'uitgevonden' (nikhef.nl was in 1992 één van de drie internetsite ter wereld; de andere waren cern en slac)

Nikhef director Jorgen D’Hondt has appointed two associate directors to support him in representing Nikhef in national and international forums in particle and astroparticle physics. www.nikhef.nl/en/news/new-...

The CERN Council has released the recommendations of the European Strategy for Particle Physics. These were finalised in early December during a session in Ancona, Switzerland. www.nikhef.nl/en/news/euro...

The ALICE experiment at CERN has unravelled the formation of light atomic nuclei that are occasionally produced in collisions in the LHC accelerator. They are publishing their findings today in the scientific journal Nature. www.nikhef.nl/en/news/alic...

Theoretisch natuurkundige Jordy de Vries van de UvA en Nikhef ontvangt een ERC-beurs voor precisieberekeningen aan ondermeer drie vormen van bètaverval. Dat zou zonder grotere versnellers toch een aantal fysische raadsels kunnen beantwoorden. www.nikhef.nl/news/theoret...

Leuk dat jullie er waren! 🤩

Goed begin vd week voor 1e/2e jaars @nikhef.bsky.social PhDs! De onderzoeksschool organiseert regelmatig 'topical lectures (coördinator - @fladias.bsky.social). Deze week: neutrino's. Schitterende line-up 🤩. Niet de bedoeling dat we als staf aansluiten ... maar misschien doe ik het stiekem toch 🤫

It's a wrap! No more #LHC collisions this year - it's time for the "year end technical stop" op-webtools.web.cern.ch/vistar/

One month ago the Beam Splitter (BS) tower was installed in the bottom part of the vacuum vessel at #ETpathfinder. Now that all filters have been tuned, the vacuum vessel can be closed. @maastrichtu.bsky.social @nikhef.bsky.social @einsteintelescope.bsky.social youtu.be/6-TxZI1W8tA

Merry Christmas Tree! 😀😍🎄🎄🎄🎄🎄🎄

PhD candidate Clara Gatius from Nikhef used the KM3NeT neutrino detector at the bottom of the Mediterranean Sea to search for dark matter. Watch the PAPERCLIP video in which Clara explains her thesis: www.youtube.com/watch?v=wh1F...

#ThrowbackThursday to 1976 👷 Here we see an electrical vehicle called Pefra, which was often used by scientists and technicians to move around the 7km Super Proton Synchrotron’s (SPS) underground tunnel.

🏳️‍🌈 Yesterday it was #LGBTSTEMDAY #LGBTSTEMDAY #LGBTQIASTEMDAY! 🌈 We'd like to share the view of our management on KM3NeT as an inclusive working environment in STEM 🏳️‍🌈 And we'd like to remind you of: Diversity and Inclusion (lnkd.in/eQ4yBJuK) Code of Conduct & Ethical behaviour (lnkd.in/eUirycxc)

The LIGO, Virgo and KAGRA gravitational wave detectors are today completing their longest observation period ever. The result: more than 250 new space-time vibrations in two and a half years. www.nikhef.nl/en/news/grav... @egovirgo.bsky.social @ligo.org

Eighty PhD students and postdocs are participating this week in the first international PHYSTAT winter school on artificial intelligence and statistics. In The Netherlands, organised by Nikhef. www.nikhef.nl/en/news/nikh...

This week, the Netherlands contributed its national input to the discussion on the new European Strategy for Particle Physics (ESPP). This involves more than just choosing a larger accelerator, says Eric Laenen, member of the ESPP Strategy Group. www.nikhef.nl/en/news/fcc-...

Op een speciale bijeenkomst op CERN hebben de lidstaten eind vorige week besloten de studies naar een toekomstige deeltjesversneller voort te zetten. Fysisch is het project favoriet, maar meer huiswerk is gewenst, aldus de raad. www.nikhef.nl/news/cern-li...
