21010SP Simulate a diffractometer

Beamline I16 is a world leading instrument for studying subtle properties of novel materials, from charge-ordering in superconductors to antiferromagnetism in Mott-insulators, and so much more besides! The versatility of this instrument is due in part to the large 6-axis diffractometer that can rotate a sample, or sample environment, through almost any orientation and position a suite of detectors at a range of useful positions for diffraction experiments. The diffractometer is essentially a large, heavy robot that moves in specific directions very precisely (for more info Google “Diamond I16” or “Kappa Diffractometer”). The many axes of the diffractometer mean that visualising its movements can be a challenge, with the potential for damaging collisions always a possibility. Indeed, users and staff have previously been known to draw diagrams and make models to pre-empt its motion!

In this project, you will create an interactive 3D model of the 6-axis diffractometer using a combination of python programming and 3D visualisation software. The aim is to create a piece of software that can be used by anyone on the beamline to simulate motions of the diffractometer, anticipating collisions and beneficial diffraction conditions for experiments. You will be free in your choice of solution but will have guidance on the working of the diffractometer and design of the software. You will have access to CAD drawings of the diffractometer and the mathematical formulas that define the movement of the diffractometer. If it is possible you will have the opportunity to see the beamline in action and work with the beamline team on experiments and testing. Working on a synchrotron x-ray beamline can be challenging and stressful but also highly rewarding!
