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


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


Detectors


Point
-
counting detectors (e.g., SSD)


high resolution


Area detectors (IP, CCD, 3D, …)


Time resolved


Background


Collimation


Subtraction


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


Amorphous/liquid scattering


Large Q (high E)


High flux


Background


“Flexible” optics



Software


Man power


Single crystal
