Structure of Nanoscale-Pitch Helical Phases: Blue Phase and Twist-Bend Nematic Phase Resolved by Resonant Soft X-Ray Scattering

Resonant soft x-ray scattering (RSoXS) at the carbon K-edge was used to probe periodic structures of phases with orientational molecular order but homogeneous electron density distribution. This approach can be applied to structures with periodicities below the optical wavelength, to which neither optical nor classical x-ray diffraction techniques are sensitive. Read more »

Cast Your Vote in the “Science as Art” Competition

The ALS Science as Art Competition debuts next week at the User Meeting. The contest features scientific images and photographs that show the aesthetic side of ALS data and instrumentation. In addition to the in-person vote during the poster session on Oct. 2, everyone is invited to take part in the public vote. Cast your ballot by 4 p.m. PT on Oct. 3. Read more »

User Meeting Live Tweeting!

The “official” hashtag of the ALS User Meeting is #ALSUserMtg. If you’re attending, the ALS invites you to use the hashtag to share photos of your experience: post your poster, your sunset selfies, or your favorite speaker(s). Report on the latest science news, meetups with colleagues, or give your review of the food! If you can’t make it to the meeting this year, you can follow what’s happening on Twitter, #ALSUserMtg, from October 2-4, 2017. Read more »

Project Director’s Update on ALS-U

In the last year since ALS-U received approval of mission need (CD-0) from DOE, we’ve made a lot of progress. I’d like to share some updates with you as well as offer opportunities for our users to engage in the next phases of the project. Read more »

ALS-U Science Workshop Report Now Available

The report from the January 2017 workshop, “Solving Scientific Challenges with Coherent Soft X-Rays,” is now available for download. The report details scientific challenges that ALS-U will address early on and identifies the instruments and tools essential for taking full advantage of ALS-U’s capabilities. Read more »

Berkeley Lab and SLAC Host Hard X-Ray Photoemission Conference

Earlier this month, Berkeley Lab and SLAC hosted the 7th International Conference on Hard X-Ray Photoelectron Spectroscopy (HAXPES). This biennial meeting has grown from a small workshop held at ESRF in 2003 with about 50 participants, to a truly international event, which this year attracted 150 participants from 20 countries.
