DECTRIS emerged from one of the largest and most significant experiments in particle physics: the CMS experiment, which proved the existence of the Higgs Boson. With PSI's visionary efforts and the transfer of the technology to a company, hybrid photon counting was made available to a much broader scientific community. X-ray and electron detectors supplied by DECTRIS today have made an impact in a variety of applications, including structural analysis in life sciences like protein crystallography and materials science, as well as plasma spectroscopy in energy science.
Last year, DECTRIS launched the world's fastest electron detector for 4D STEM, an emerging structural method in materials science. This method enables novel contrast mechanisms that ultimately allow identifying and resolving atomic-level structures that were previously not visible to researchers. To provide such a detector, multiple technologies must be developed, including fast data pipelines, ASIC pixel designs, software infrastructure, and Micro-Nanotechnologies. We partner with various universities, start-ups, and companies on projects continuously to understand, master, and integrate new technologies into the next-generation detector. In this way, and driven by specific requirements, we can bring back detectors with unique new properties to the scientific community to advance their research.
In my talk I will review current sensor types and materials for X-ray and electron detection, their specific requirements for different applications as well as their current limitations. I will elaborate on the evolution of these materials and their properties also from an industrial point of view. With that in mind, I will conclude with our expectation for properties and availability of perovskite materials for X-ray and electron detection in the future.
