Figure 7
x–y plots of diffraction patterns versus time (frame number) showing the transformation of gypsum–bassanite–anhydrite. The sample temperature increases with frame number and the collection time for each frame is 1 s. Higher intensity is represented by darker shading. (a) Energy-dispersive data collected on station 16.4. (b) Monochromatic data collected on station 6.2. The data range and angular resolution are far superior with the monochromatic data. The MPW6.2 data were collected 1/3 faster than the energy-dispersive data and each pattern has yielded refinable data. |
