SLAC National Accelerator Laboratory

This deep-underground experiment has cooled to near absolute zero. That’s cold. Real cold. It will become one of the world’s most sensitive dark matter searches, & it’s achieved an operating temperature about a hundred times colder than outer space: stanford.io/4rFnyKu

@VRubinObs 8⃣It was built here at SLAC! It took approximately two decades of work to complete, with construction completed in 2024.

4️⃣ It produces an enormous amount of data 5️⃣ It's incredibly sensitive 6️⃣ Rubin's First Look on June 23, 2025 showcased its incredible capabilities 7️⃣ It will capture over two million images for the 10-year Legacy Survey of Space and Time

A year ago this month, our 3200-megapixel LSST Camera was installed! Here's what to know about it! 1️⃣ It's enormous! 2️⃣ It sees a huge area of sky at one time 3️⃣ Everything about it is huge, including the images it takes 🧵

Reconstructing a molecule? There’s an AI for that… Meet MOLEXA, the generative AI model that can recreate the structure of a molecule after its ions have been blasted apart by X-rays: stanford.io/47RdaYK

It’s not easy being green… 🍀 🧪 💚 Wishing "good luck" to all the science and experiments that are taking place this #StPatricksDay.

@INL #DYK that the first World Wide Web server in the United States was created here at SLAC? 😀www6.slac.stanford.edu/news/2011-12-1…

Hey @INL, what were you like in the 90s? 📸 This decade saw the launch of the World Wide Web along with innovative INL #energy and security solutions that continue to shape our world today. More on our history: inl.gov/history/ #90sTrend #Research #Nuclear #Energy

Seen a-round SLAC ⭕ We may be known for a linear particle accelerator, but we also want our piece of the #PiDay! Plenty of SLAC science goes full circle. Recognize any of these from the lab?

"If you can’t actually deal with the data, what was the point of taking it?” – SLAC Lab Director John Sarrao More from @NewsFromScience on how AI at the labs can help us process massive amounts of data & support @ENERGY’s Genesis Mission: bit.ly/4lq45vD

Solving conflicts in cosmology 🌀 🔎 The most realistic simulations of magnetic fields in the early universe to date could resolve “the biggest problem in cosmology right now” - the mysterious Hubble Tension: stanford.io/3P4sKtO

Meet The Plastics. An exclusive group of materials that can take centuries to break down in landfills or the environment. Ozge Bozkurt is improving our methods for breaking down plastic waste into useful products. #SLACPublicLecture on March 26: stanford.io/4cCQ1g8

@VRubinObs Learn how Rubin will process and sift through all that new data in the full video: bit.ly/4sZxAr1

This is @VRubinObs. Rubin will scan the entire night sky for 10 years, generating up to 10 terabytes of data per night. The resulting Legacy Survey of Space and Time (LSST) will create the most comprehensive, cinematic record of the universe in history.

Mixing X-rays and optical lasers 〰️ ⚛️ A new method for tracking valence electrons could lead to novel superconductor materials, quantum tech, and more. Learn how: stanford.io/4dl5XDQ

@Mick_Goulish @VRubinObs We sure do! Our work didn't end when we delivered the camera. We are joint operators of @VRubinObs alongside @NOIRLabAstro, and all of its data comes to the U.S. Data Facility first, right here at SLAC!

@SLAClab @VRubinObs SLAC! I guess you guys probably know something about generating a lot of terabytes per day!

Alerts from NSF–DOE Rubin Observatory have been flowing for about a week...how many have there been?? 🚨 So far, Rubin has generated....drumroll please🥁 ~1.7 million world-public alerts! That's ~1.7 MILLION objects that changed in brightness or position in just seven nights🤯

@DKlemitz Both!

@SLAClab temporally or spatially or both ?

Perfectly coherent! SLAC researchers are developing an X-ray laser oscillator designed to emit perfectly coherent X-ray pulses - and it's almost ready! A prototype will be built and tested at SLAC’s LCLS and Japan's SACLA X-ray laser facilities: stanford.io/3OO7isM

@intspg @Collosal_60 Yes! Due to internal full source coherence there are general advantages in imaging applications, including microscopy.

@SLAClab @Collosal_60 What about for microscopy?

Keep your eye on the beam. Roughly 95% of researchers using our pioneering X-ray light source, SSRL, run their experiments remotely. Automated robotic systems and beamline scientists like Silvia Russi make that possible: stanford.io/408JL8t

@Mick_Goulish @VRubinObs 😊

@VRubinObs The biggest camera that has ever been made. I think I'm in love. How many terabytes so far?

@Collosal_60 For lithography itself perhaps not, since the XLO radiation is very coherent. But it will be very useful for validation post lithography process.

@SLAClab Will this be helpful for X-ray lithography?
