This project aims at building and using a computer model of the MAX IV X-ray beamline NanoMAX which is currently being designed for the MAX IV synchrotron radiation facility in Lund.
The NanoMAX beamline [https://www.maxlab.lu.se/nanomax] is to be a flagship beamline for the MAX IV X-ray facility in Lund, Sweden. MAX IV is one of the world’s leading synchrotron facilities providing extremely intense X-ray beams (above 10^10 times more brilliant than a laboratory source). Modern X-ray beamlines consist of a wide range of devices, all of which have to perform to their optimum. This means that accurate beamline computer models are extremely important. DTU and KU are collaborating with MAX IV in the race to provide the most accurate and efficient beamline and beamline models.
As its name suggests, NanoMAX will provide a beam of nanometer size for a multitude of applications in physics, chemistry and biology. One particular parameter here is that when focussing the beam this much it inherently becomes highly coherent which opens up exciting new possibilities for science [https://www.sciencemag.org/content/334/6060/1234.full].
Below is a sketch of the NanoMAX beamline and the most important devices that the beam passes through on its way from the source to the sample and detectors.
The project involves numerical modelling of the beamline, with the aim of building an accurate model to optimize the beamline, so that it may achieve the goal of a 10 nm X-ray beam spot. Building a full beamline model is a great task even for experienced scientists. It makes sense to split the project into subprojects. These can all be combined into a unified coherent project.
Some sub-project may be formulated into master/bachelor projects - many others exist:
- Fresnel Zone-plate modelling
- Tracking beam coherence through the beamline model
- More accurate monochromator models to correctly handle coherence properties
- Connecting the software packages MASH and McXtrace [http://www.mcxtrace.org].
...and many more
The projects will be carried out in strong collaboration with the MAX IV facility, and students will make visits to the MAX laboratory in Lund.
