3D characterization of Lunar regolith particles

What to expect:

The surface of the moon is covered with a fine powdery material called "lunar regolith". The overall mechanical behavior of granular materials such as lunar regolith is strongly affected by the properties of individual grains (grain shape) and their composite behavior.

Usually, and problematically, shape measurements of the solid particle are obtained only from two dimensions. It is well known that, in general, a given 2D shape measurement cannot be uniquely related to a solid. In addition, CT scan imaging for large amounts of grains is very slow procedure and expensive.

The experimental setup shown below enables floating, rotating particles to be captured in real time from different angles.

The test setup consists of a glass tube through which Nitrogen gas is passed to keep particles suspended. Moreover, a high-speed camera is installed on the glass tube, which can be upgraded to two cameras to observe the particles from two directions. Finding the best configuration of camera and backlight for high-quality imaging is part of the lab work. Additionally, micro CT scan, SEM, and optical microscope devices are available for comparison between particles and further insights into their characteristics.

Your Requirements

What we offer:

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.
