# xrdPlanner
#### A tool to project X-ray diffraction cones on a detector screen at different geometries (tilt, rotation, offset) and X-ray energies
 - Main application is to visualize the maximum achievable resolution at a given geometry.
 - Is able to project diffraction cones for standard samples or directly from cif files.
 - Can turn out valuable when planning beamtimes and deciding on the geometry of the experiment.
 - The math used is not meant to bring people to the moon but to provide a quick and simple preview.
 - The module building code is designed for [Dectris](https://www.dectris.com) [PILATUS3](https://www.dectris.com/detectors/x-ray-detectors/pilatus3/) / [EIGER2](https://www.dectris.com/detectors/x-ray-detectors/eiger2/) and [SACLA](https://sacla.xfel.jp/?lang=en) MPCCD Detectors (central hole geometry) but one-module systems like the [Bruker](https://www.bruker.com/en.html) [Photon II](https://www.bruker.com/en/products-and-solutions/diffractometers-and-scattering-systems/single-crystal-x-ray-diffractometers/sc-xrd-components/detectors.html) are possible as well.
 - It uses [python3](https://www.python.org), [numpy](https://numpy.org), [pyqt6](https://www.riverbankcomputing.com/software/pyqt/), [pyqtgraph](https://pyqtgraph.readthedocs.io/en/latest/), [pyFAI](https://pyfai.readthedocs.io/en/v2023.1/) and [Dans_Diffraction](https://github.com/DanPorter/Dans_Diffraction).

## Short how-to:
 - Type _xrdPlanner_ in a terminal and hit enter.
 - Choose a detector and a model from the _Detector_ menu.
 - Pick a reference from the _Reference_ menu to plot its contours ([pyFAI](https://pyfai.readthedocs.io/en/v2023.1/)).
 - Drop a .cif file onto the window to draw its contours ([Dans_Diffraction](https://github.com/DanPorter/Dans_Diffraction)), click a contour to get a hkl tooltip.
 - Use the units from the _Units_ menu you are the most comfortable with.
 - Hover over the grey line at the top to show the sliders. Click it to make it stay open.
 - Drag the sliders to change energy and geometry.
 - Edit the _settings.json_ file to suit your needs.
 - Add all the missing detectors to the _detectors.json_ file.

## Latest updates:
  - 2023-06-14 Update: Big speed update.
  - 2023-06-01 Update: countourpy was dropped, the conics are now calculated directly instead of being evaluated on a grid.
  - 2023-05-25 Update: Dans_Diffraction is used in favour of gemmi as it allows the direct calculation of intensities from the cif.
  - 2023-04-26 Update: A hkl tooltip is shown on click on a contour (only for cif contours).
  - 2023-04-25 Bugfix: Segmented contours are now drawn properly.
  - 2023-04-20 Bugfix: Confined slider window mobility to main window area.
  - 2023-04-10 Bugfix: Main window aspect ratio on Windows (menu bar within window).
  - 2023-04-10 Bugfix: Label size could not be adjusted.
  - 2023-04-10 Bugfix: Large angle (2-Theta > 90) contour label positions.
  - 2023-04-09 Update: Drop a cif file onto the window to draw its contours (uses [Dans_Diffraction](https://github.com/DanPorter/Dans_Diffraction)).
  - 2023-04-05 Update: Uses pyqt6, pyqtgraph and contourpy, dropped matplotlib backend.

## Older updates
  - 2023-03-23 Update: Settings are saved to (if doesn't exist) or loaded from (if exists) a 'settings.json' file.
  - 2023-03-23 Update: Added horizontal offset support and slider.
  - 2022-06-07 Update: Added functionality to plot Standard (LaB6, CeO2, ...) contours (needs [pyFAI](https://pyfai.readthedocs.io/en/master/)).
  - 2022-04-28 Update: Changed contour line generation to accept a list of 2-theta values as input.
  - 2022-04-27 Update: Added support for [SACLA](https://sacla.xfel.jp/?lang=en) MPCCD Detectors (central hole geometry).
  - 2022-04-25 Bugfix: Calculation of the beamcenter (rotation and tilt).
  - 2022-04-25 Bugfix: Unresponsive radio buttons / redrawing the figure.

#### I hope this turns out to be useful for someone!
