. A detector for 2D measurements of simultaneously capturing large angular ranges and rapid changes in high-temperature tests should have the following characteristics:

- Surface> = 2750 mm;

- Pixel size <= 175 microns;

- Operating with no gas, air cooling.

B. requires a tube mount, aperture, shutter assemblies, optical benches, glass gap, alignment tools, dynamic scintillation detector holder, absorbers, filters, micro masks, reference materials, etc. for the various configurations and tests described.

ICSD database) are present.

An automatic component identification, configuration, and calibration of the components and a conflict detection by the software are necessary or desirable.
