Expanding the Infrared Nanospectroscopy Window

An innovative infrared-light probe with nanoscale spatial resolution has been expanded to cover previously inaccessible far-infrared wavelengths. The ability to investigate heterogeneous materials at nanometer scales and far-infrared energies will benefit a wide range of fields, from condensed matter physics to biology.

COSMIC Ptychography Team Receives 2018 Klaus Halbach Award

The 2018 Klaus Halbach Award for Innovative Instrumentation at the ALS was presented at the annual User Meeting to the COSMIC ptychography team “for the development of the microscopy endstation at the COSMIC beamline, featuring an ultra-stable x-ray microscope, computational methods for data reconstruction, and a high-speed data acquisition system.” Read more »

Antibody Therapy for Autoimmune Diseases

The balance between two types of white blood cells is disrupted in autoimmune diseases. Using protein crystallography, scientists have identified a human antibody that locks interleukin-2, a signaling protein, in a conformation that preferentially activates one cell type to restore the balance and treat autoimmune diseases.

ALS-U Project Receives CD-1 Approval

The ALS Upgrade (ALS-U) project has received federal approval (CD-1) to proceed with preliminary design, planning, and R&D work. This major upgrade will boost the brightness and coherent flux of ALS soft x-ray beams at least a hundredfold, enabling transformative science that cannot be performed on any existing or planned light source in the world.
