2.3 Measurement Parameters
Measurement parameters to be used are listed in the first table for Cu radiation and in the
second table for Co-radiation, respectively. Depending on specific measurement setups, indi-
vidual reflections may not be measurable. Continuous sample rotation speed of 15 rpm is
recommended. For statistical reasons each peak requires a minimum of 1000 counts at the
peak maximum, step times must be adjusted accordingly.

For linear detectors measure all reflections in one uninterrupted range (from 20°to130°
in 2Theta) with smallest possible step width and step time 0.5s. For LYNXEYE/
LYNXEYEXE/ LYNXEYEXE‑T/ SSD160/ LYNXEYE‑2/ SSD160‑2 and
EIGER2R500K use step size of 0.005 and step time 0.5s. For evaluation limits use
values given as scan angles for point detector.
