Residual Stress Measurements

Shortly after their advent, the MYTHEN microstrip detectors were recognized as a great solution for taking in-situ strain measurements at synchrotron sources, due to their high 2θ coverage, speed, and sensitivity. The excellent data generated by these large, multimodular detectors relied on the combination of features: noise-free performance, an ability to suppress fluorescence, and extremely high resolution.

Nowadays, microstrip MYTHEN2 detectors are combined with a variety of X-ray sources (from Ti to Ag) to handle difficult residual-stress and retained-austenite measurements that require very short exposure times, sample scanning, and detection of low austenite amounts. The newest hybrid-pixel detectors offer all of that, but in two dimensions: a 2D detector in the EIGER2 product family is ready to tackle future challenges.

However, MYTHEN’s modularity and ability to scale down were equally important for residual stress experiments. By using only two detector modules, it was possible to arrange an experimental setup that was needed for the sin2ψ method and to transfer the technology to laboratories and portable machines.
