    Superheating gold 14x beyond its melting point resulted in a surprise – the metal stayed solid. Now SLAC scientists blasted a thin copper film with laser heat & observed an unexpected gradual melt instead of the atomic structural collapse they expected: stanford.io/4xHOBbx

    Rubin storm update: Teams have now reached the summit of Cerro Pachón & assessed @VRubinObs following July’s severe winter storms. The camera & observatory are in good condition, but significant work remains before operations can resume. Safety remains the highest priority.

    We welcomed California Representatives @JayObernolte, @RepKevinMullin & @RepLiccardo to SLAC! Representatives Mullin and Obernolte also toured state-of-the-art facilities that help us explore how the universe works at the biggest, smallest & fastest scales.

    Fog log: “Fogust” is here 🌁 We’re used to it. Summer mornings often mean gray skies in the San Francisco Bay Area. Sometimes mixed with a little condensation from the cryoplant that cools our X-ray laser.

    Marking 20 years of Ultrafast X-ray Summer School! More than 2,000 trainees have come through this program – from members of detector teams to area managers – preparing the next generation of X-ray scientists for the next generation of X-ray lasers.
