How to Create a Custom Run List and Position the Goniometer Precisely 

Christian Schürmann explains how to gain full control over your X-ray diffraction experiments by creating custom run lists in CrysAlisᴾʳᵒ. In this video, you will learn how to manually edit run lists in both the offline version for data reduction and the online version for starting new experiments. Christian demonstrates how to add single Omega or Phi scans, define start and end angles, and set specific detector (Theta) and Kappa positions. Key topics covered in this tutorial:

• Collision Management: Learn how to use the collision map to ensure your custom scans stay within safe ranges

• Avoiding the "Icing Zone": Understand what the white area on the collision map represents and why avoiding long scans in this zone is critical to preventing ice buildup and sample de-centering

• Optimization Tools: Discover how to use sorting functions—including sorting by theta or kappa and optimizing drive time—to make your data collection more efficient

• Visualization Pro-Tip: If you find Eulerian geometry easier to visualize than Kappa geometry, Christian shows you how to use the Euler to Kappa calculator via the gt e command to translate angles and move the goniometer to precise orientations

Whether you are importing existing lists or building a unique strategy from scratch, these tricks will help you refine your experimental setup.
