X-ray Upgrade

The recent upgrades to Stanford’s particle accelerator, nestled within the Department of Energy’s Stanford Linear Accelerator Center (SLAC), have ushered in a new era of scientific exploration with the successful production of X-rays. The Linac Coherent Light Source (LCLS), now christened LCLS-II, boasts the astonishing capability to emit up to a staggering one million X-ray pulses per second, a mind-boggling 8,000-fold increase compared to its predecessor. Not stopping there, it produces a nearly continuous beam that shines 10,000 times brighter than the previous version. This dazzling technological leap is set to pave the way for groundbreaking research into the realm of “atomic-scale, ultrafast phenomena,” casting a spotlight on quantum computing, communications, clean energy, and medicine.

What’s the secret behind this accelerator’s Herculean upgrade, you ask? Well, it’s all in the cooling. The original LCLS, which debuted back in 2009, was limited to a modest 120 pulses per second due to the inherent constraints of having electrons traverse room-temperature copper pipes simultaneously. However, this souped-up edition features a whopping 37 cryogenic modules, chilled to a bone-chilling -456 degrees Fahrenheit (yes, that’s colder than the vast expanse of outer space). This extreme cooling allows the accelerator to “supercharge” electrons to incredible energies with minimal energy loss. Intriguingly, this new accelerator will work in tandem with the existing copper-based one, synergizing their powers.

The potential unleashed by this upgrade has researchers at SLAC brimming with excitement. With these new capabilities, they anticipate delving into the intricate world of quantum materials with unparalleled precision, opening doors to novel forms of quantum computing, and unveiling hitherto unseen and transient chemical phenomena that can propel clean energy technologies forward. Moreover, they foresee the study of biological molecules on an unprecedented scale, which could revolutionize pharmaceutical development. As if this weren’t enough, the astonishing 8,000 flashes per second will usher in entirely new frontiers of scientific investigation.

The journey toward this groundbreaking achievement began in 2010 when SLAC researchers first conceived of upgrading the original LCLS. This monumental endeavor has consumed a staggering $1.1 billion and has been a collaborative effort involving “thousands of scientists, engineers, and technicians across DOE, as well as numerous institutional partners.” The project demanded the integration of cutting-edge components, including a new electron source, two cryoplants to produce refrigerant, and two new undulators to generate X-rays from the beam. Multiple institutions joined forces to make this vision a reality, with five US national labs, such as Lawrence Berkeley National Laboratory and Argonne National Laboratory, alongside Cornell University, playing pivotal roles.

Mike Dunne, Director of LCLS, enthused, “Experiments in each of these areas are set to begin in the coming weeks and months, attracting thousands of researchers from across the nation and around the world. DOE user facilities such as LCLS are provided at no cost to the users — we select on the basis of the most important and impactful science. LCLS-II is going to drive a revolution across many academic and industrial sectors. I look forward to the onslaught of new ideas — this is the essence of why national labs exist.”

In essence, the upgraded LCLS-II at Stanford’s SLAC is not merely a marvel of scientific achievement; it’s a beacon illuminating the path toward a brighter, more innovative future across numerous domains of human endeavor. So, fasten your seatbelts, because the scientific journey is about to get even more thrilling!
