These X-rays can take internal images of fossils, brains, batteries and countless other interesting things up to the atomic scale, revealing unprecedented information, thus facilitating scientific research. < / P > < p > when people encounter a fracture, they will go to the hospital to take X-rays. These typical medical X-rays can show doctors the details of the fracture site and surrounding tissues. When X-rays penetrate the human body, they are absorbed by different tissues at different rates; after passing through the body, these rays will collide with the detector, forming the familiar black-and-white X-ray images. The X-ray power generated by EBS will be 10 trillion times more powerful than that of X-rays used in hospitals. With such x-ray beams, scientists can draw three-dimensional images of the fracture site in detail, even the individual atoms in blood cells around the fracture. Of course, you don’t want to be hit by this X-ray beam – this dose of radiation is lethal. < / P > < p > EBS seems to open up endless possibilities. One area particularly exciting for ESRF director Francesco seter is the study of brain structure and function, which may eventually lead to the development of brain like electronic products. “It’s going to be a major revolution, not just for neuroscience, but for all applications that could use human brain structures for a new generation of devices,” Seth said < / P > < p > using synchronous X-ray imaging technology, engineers can gain insight into innovative materials and help in areas such as aviation and nanoelectronics. Paleontologists can study the tiny structures inside fossils without destroying them. Novel coronavirus pneumonia was used by scientists in the summer of 2020, and some scientists used EBS to identify lung damage caused by the new crown pneumonia. They identified the damage on the microscopic level, which has never been observed before. A synchrotron is a simple particle accelerator that uses a magnetic field to accelerate charged electrons to extremely high energy, causing them to emit X-rays – also known as synchrotron radiation light. Unlike the Large Hadron Collider, particles that “circle” around the ring of a synchrotron do not collide with each other. The X-rays produced by fast circular electrons are siphoned out of the accelerator ring and enter 44 specialized laboratories, namely beamlines. The researchers then use these beams to image the target. In recent decades, synchrotron based science has helped drive many breakthroughs, including recently allowing researchers to see the inner structure of unripe dinosaur eggs and reading an ancient book destroyed by volcanoes. < / P > < p > the ESRF in Grenoble, France, has been in operation since 1994. The facility has previously had the world’s most powerful X-ray source, and this year’s upgrade has increased its performance by 100 times. The facility was closed in December 2018 and the transition to EBS began. Fortunately, the novel coronavirus pneumonia epidemic did not postpone the official opening of August 25th, and the project was nearly five months ahead of schedule. Seter said the x-ray beams are already being used by researchers and the first results of recent synchrotron work should be published soon. < / P > < p > what makes this significant upgrade possible is a novel design, a lattice of 1100 magnets that drives electrons through a 844 meter long ring. These magnets not only speed electrons forward, but also give them a slight boost and change their direction. These small changes in direction are the key to X-ray production. < / P > < p > this is a simple law of conservation of energy. When you bend an electron beam so that it moves in a circular rather than a straight line, each time the electron changes direction, it loses a little energy. This loss of energy exists in the form of light. To get the light emitted in the X-ray frequency range, you need to provide a stronger magnetic “boost.”. The new magnetic lattice design makes it possible to continuously bend and refocus electron beams, which can generate a large number of high-energy X-rays without the need for larger annular devices. < / P > < p > another area that may be significantly promoted by EBS is histology, the microscopic study of biological tissues. Now, histologists study tissue by slicing it into many very thin samples and dyeing it with dyes to show its microstructure. With synchronous imaging, samples do not need to be sectioned and stained; researchers can also image them as a whole, creating high-resolution three-dimensional scanning images that show more detailed anatomical structure information. < / P > < p > “it’s called ‘3D nanohistology’ and it’s a medical dream,” Seth said. “It represents a radical revolution in the field of histology.” Victor Gonzalez is a postdoctoral researcher in the science department of the National Museum of Amsterdam in the Netherlands. He has used the previous generation of European Synchrotron for research. Gonzalez often uses synchrotron imaging to study paintings from centuries ago. His recent work reveals the details of Rembrandt’s painting techniques. < / P > < p > “it’s very important for my research team to upgrade the ESRF,” Gonzalez said. “The facility’s new state-of-the-art analytical capabilities will allow us to analyze valuable samples more quickly. An experiment that used to take a few days can now be completed in an afternoon! This means that we suddenly have a lot of data, which provides a new opportunity to understand the chemical mechanism of historical pigment layers. ” < / P > < p > now that EBS is up and running, scientists around the world can apply for beamline time. It’s a competitive process – research applications must be peer-reviewed before scientists can get a chance to use synchrotrons. However, with the new upgrade, experiments that used to take weeks can now be completed in a day; work that used to take a day now takes just a few minutes. In the next few months, there may be a lot of exciting new scientific results. Chinese version of K-car: reading a10e design drawing exposure
