P2 - Panalytical Empyrean
Overview
Panalytical Empyrean vertical diffractometer with 4 circles: ω, 2θ, χ, φ and a z motor (no x or y). Set up with parallel beam optics, useful for oriented work. Can be used with simple sample holders or at high temperature with an Anton Parr domed heating stage. There is a standard proportional detector and a position sensitive detector that can be used in a variety of different modes, which is useful for e.g. fast reciprocal space mapping.
Optics
By default parallel beam optics with CuKα1 radiation in line focus, normally used in reflection mode.
Incident beam: hybrid 2-bounce primary (CuKα1), or graded mirror (more intense - CuKα1,2).
Secondary beam: Two separate optical paths. Can have open detector or 2θ defined by slits set as a beam tunnel, a parallel plate collimator, or a 2-bounce analyser crystal for better resolution but lower intensity.
Automatic and manual absorbers can be used, some slits are motorized.
Detectors
Single point proportional detector, or a PIXcel3D position sensitive detector for fast reciprocal maps.
Resolution
- 0.0001° minimum step in source and detector
- ~0.007° best resolution in ω
- ~0.018° best resolution in 2θ
Training videos
There is a short introductory video for researchers wishing to use P2 for their research. This video gives a brief tour of the instrument and is intended for researchers who wish to familiarise themselves with the instrument prior to getting formally trained to use it as well as existing users who wish to refresh their knowledge.
