Modern X-ray detectors

Wilhelm Röntgen discovered X-ray November 8th 1895, when he did experiments with cathode rays in a vacuum tube. To capture and save images of the shadows from the X-rays, he used ordinary photoplates. Fortunately, sensitive to visible light silver based photoemulsions turned out to be sensitive to the X-ray too. These photoplates became the first X-ray detectors.

More than 100 years of scientific progress led to the creation of a number of various detectors for recording X-ray images. Developments of the microelectronics and semiconductor manufacturing technologies are crucial for development of the modern X-ray detectors. These detectors can transform the energy of the X-ray photon directly to the electrical signal. They allow capturing detailed, digital, high-resolution X-ray images.

Digital images are easy to work with. For example one can merge multiple macro images into an image of the whole object and represent monochrome images in false colors like Simon Procz did with this X-ray image of a flower he did in 2012.

The goal of the Intelligent Systems Department is to facilitate the road to high-quality professional life. The Ph.D. degree requires three publications in peer-reviewed journals. They are the core of the student’s thesis. This year each of our bachelor students delivered at least one publication. It means they pave the road to their Ph.D. To facilitate this, the Department provides state-of-the-art research topics, scientific advisors with excellence in science, and fine-tuned educational courses. Below, we are proud to recognize our students for their outstanding achievements.

Prospects for the development of modern GTP and an alternative way of their development

We wrote this article in an attempt to figure out what technical level gas turbine installations are currently at, as well as to understand what the prospects for their development are. At the same time, in our manuscript, we tried to consider an alternative energy conversion scheme that will increase energy efficiency, which will allow for more efficient use of natural resources. We are not completely sure that the alternative scheme presented by us will be workable, since many factors that may affect its operation have not yet been investigated. But as the Chinese philosopher said, "you can't travel a thousand li without taking the first step." We ask the Habr community to read our article, we hope for a constructive conversation.
