An image with the CHESS ID4B beamline and soft photon scattering

Combining the 6M Pilatus detector with closed cycle cryostats and rotary vacuum shrouds allows effectively windowless, near-zero background measurements of single-crystal diffuse scattering at liquid helium temperatures at CHESS beamline ID4B (left). This enables precise measurements of weak scattering features over a broad range of reciprocal space. For example, soft phonon scattering can be observed in half-integer planes of hybrid perovskites (right).

Beamline ID4B is purpose-built to study low-temperature phases of quantum materials in Q space. Combined REXS and high-energy mapping techniques offer a comprehensive overview of order and disorder. Innovative computational tools are required to understand the large datasets generated. We plan an interdisciplinary workshop that will imagine growth opportunities for the quantum materials program at ID4B, including new perturbations, techniques, materials, detectors, optics, and algorithms.

Talks will focus on research opportunities enabled by new materials and new methods, and explore our ability to resolve and control new quantum states at next generation CHESS x-ray beamlines.
