The Alpha Magnetic Spectrometer (AMS) is a particle-physics detector attached to the outside of the ISS, searching for Dark Matter, #antimatter and missing matter. Here we see “Layer-0”, a new layer of silicon sensors which will be mounted on top of the AMS while it orbits Earth on the ISS.
77 tonnes on the move 🚚 On 22 July, the 77-tonne JFSU-C, a shielding component used in the @atlasexperiment.bsky.social , was transported from the ATLAS cavern to Building 191 – the technical workshop and integration facility used for assembling and testing large components of the experiment.
ATLAS and CMS narrow in on twin Higgs production 🔎 Finding one #HiggsBoson was hard enough, but physicists at the Large Hadron Collider (#LHC) are hunting for something even more elusive: pairs of Higgs bosons.
An experiment at the Paul Scherrer Institute in Switzerland used novel technologies to demonstrate the feasibility of the positron-source concept for the proposed Future Circular Collider at CERN. #FutureCollider Find out more: home.cern/positrons-pass-test-for-the-future-circular-collider/
