  1. Crystallography/meltsBreakout Session, Afternoon, Feb 25(Prepared by Guoyin Shen) Recommendations for X17 P-T generation and condition Probing beams – x-ray Detectors Software Single crystal project Liquid/amorphous scattering

  2. P-T generation and condition • Infrastructure (higher and better) • Stress (or hydrostacity) control and characterization • P calibration, especially at high/low T • Temperature • Laser heating • Resistive heating (external, designed, wire) • Induced heating • measurements

  3. Probing beams – x-ray • Energy • White beam vs mono beam • E range (resolution, Q coverage, transmission, cleanliness, …) • E resolution • Size, flux, collimation • <10 microns for DAC+laser heating • High E, focusing optics • Beam cleanliness

  4. Detectors • Point-counting detectors (e.g., SSD) – high resolution • Area detectors (IP, CCD, 3D, …) • Time resolved • Background • Collimation • Subtraction

  5. Single crystal • Successful at X17c • White Laure + existing technique • New “Mbar single crystal project” • Precise stages, e.g., small sphere of confusion enables small samples to be measured. • Background subtraction • Software

  6. Amorphous/liquid scattering • Large Q (high E) • High flux • Background • “Flexible” optics

  7. Software • Man power • Single crystal • On-line analysis
