Overview
Philips PW 1820 diffractometer. Ideal for measuring large powder samples. Sample rotation is also available if required.
Optics
Incident beam: divergent beam optics in reflection mode with CuKα1,2 radiation in line focus.
Secondary beam: graphite monochromator gives good energy resolution but low intensity.
All slits etc. are manual.
Detector
Single-point proportional detector.
