1. Crystallography/melts Breakout 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 Size, flux, collimation
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
