General Purpose Powder Diffractometer

Date: 2017-03-15

The General Purpose Powder Diffractometer (GPPD) of CSNS is useful for a wide range of structural studies, especially for most users to determine crystallographic and magnetic structures in general purposes.

 

Performance:

1. Best resolution Δd/d ~0.2 %.

2. ~ mimutes for a diffraction histogram used by Rietveld refinement on ~ 1-g-weight sample

3. Easily loading the ancillary equipment such as cryostat, furnace and pressure cell
