Agenda • Introduction (Miller) • Keynote Speaker: Carolyn Larabell (ALS, UCSF) (30 min) • Technique talks (4 min each) • Imaging • Soft x-ray spectromicroscopy (Jacobsen) • Diffraction Imaging (Jacobsen) • Full-field transmission x-ray microscopy (Larabell) • X-ray fluorescence micro/nanoprobe (Vogt) • Diffraction-enhanced imaging (Zhong) • Microbeam radiation therapy (Dilmanian) • Infrared microspectroscopy and imaging (Miller) • Structural & Molecular Biology: • X-ray footprinting (Chance) • XANES/EXAFS (Chance) • Macromolecular Crystallography (Stojanoff) • Small-Angle X-Ray Scattering (Yang) • Discussion • Closeout (Sweet)
Life Sciences Discussion Session Summary • What are the key scientific drivers? What experiments will NSLS-II enable that are not presently possible? • What technical capabilities will these require? (Beamlines, endstations, undulators…) • Estimate of community size. • What detector requirements does this field have? Do these require R+D? • What software and computing infrastructure requirements are there? (Control, data acquisition, analysis) • Any particular accelerator requirements? • Any particular conventional facility requirements?
Key Scientific Drivers Cross-Technique Imaging • In identical biological cells: • infrared imaging: chemical imaging of biological cells • full-field, soft x-ray TXM: nanoscale 3D sub-structure • x-ray spectromicroscopy: 3D nanoscale chemical imaging of organic components • x-ray fluorescence microprobe: 3D trace element mapping Cross-Technique Structural/Molecular Biology • For the same protein: • small-angle x-ray scattering: low-resolution structure, static & dynamic • EXAFS: metal active site environment, static & dynamic • MX: atomic-resolution structure, static & dynamic Life Sciences “Village” Environment
Technical Capabilities • Imaging • Soft x-ray spectromicroscopy (ID for tomography) • Diffraction Imaging (ID) • Full-field transmission x-ray microscopy (BM) • X-ray fluorescence micro/nanoprobe (ID) • Diffraction-enhanced imaging (SCW) • Microbeam radiation therapy (ID) • Infrared microspectroscopy and imaging (2 BM) • Structural & Molecular Biology: • X-ray footprinting (3PW) • XANES/EXAFS (DW) • Macromolecular Crystallography (6 IDs) • Small-Angle X-Ray Scattering (1 ID, 1 3PW)

Life Sciences “Village” Environment • Accelerator • Meet specs • Detectors • Limiting today for: MX, EXAFS, IR • Laboratories and ancillary facilities • Wet lab, with basic equipment (e.g., BSL2, cell culture, crystal growth, protein purif.) • Light, epifluorescence, confocal microscopes • Sample prep, in particular freezing, microtoming (ultra, cryo, RT) • Access to correlated (same mounts ?) electron, IR, and soft x-ray microscopies • Adequate staffing !!!!!! • Including people with significant background in biological sample prep. • Only supporting beamline ops is insufficient, need to support whole experiment (planning, sample prep, data analysis, interpretation)! • IT • Handling of very large datasets • ‘full’ remote control of beamline, remote access; cybersecurity, firewall issues • Quality of Life • Offices for beamline staff NEAR beamline; lab space near beamline • Sufficient floor space at beamline, AND office like controls environment
