The superconducting linear accelerator housed in the underground tunnel is meant to run accelerated electrons to almost light-speed. These then pass through a slalom (or sloping) course of magnets called undulators where, as the electrons bend and turn, they emit flashes of X-rays. The XFEL generates these extremely bright and ultrashort pulses of light at a rate of up to 27,000 pulses per second, which is 200 times faster than other x-ray lasers\u00a0\u2014 a billion times faster than light generated by synchrotrons.<\/p>\n The European XFEL\u2019s primary purpose is to help study particulate matter. For example, it can be used to map the three-dimensional structures of biomolecules and other biological nanoparticles. The idea is to capture them during the process, as they occur, whilst these samples speed through the facility. The XFEL can deliver trillions (1,000,000,000,000) of X-ray photons in one pulse that lasts just about 50 femtoseconds (0.000,000,000,000,05 sec), for each of its 27,000 pulses per second.<\/p>\n Using an advanced camera called the Large Pixel Detector (LPD), installed as part of the XFEL by British engineers, it would allow researchers to capture molecular snapshots like never before. The cameras have a frame rate of 4.5MHz \u2014\u00a04.5 million pictures per second. Furthermore, each single image can be put together to create a \u201cmolecular movie\u201d that details biochemical and chemical reactions in progress.<\/p>\n \u201cThe LPD captures the pattern of the X-rays after they\u2019ve scattered through whatever it is the scientists have put in the beam. Its imaging surface is about half a meter by half a meter,\u201d lead engineer Matthew Hart told the BBC<\/i>. \u201cIt\u2019s something we\u2019ve been working on for 10 years, and it\u2019s incredibly bespoke. It has to run really fast, handle really intense levels of X-rays but at the same time capture very small signals as well; and have very low noise.\u201d<\/p>\n In a press release about the launch, Olaf Scholz, Hamburg city\u2019s mayor had this to say: \u201cWith the European XFEL, scientists will forge ahead into unknown worlds and help to find answers to questions facing humanity that will make life on our planet better.\u201d Analyzing atomic structures can, for instance, help in understanding various process involved in diseases. Indeed, the European XFEL could even become an important tool in exploring the world of quantum particles.<\/p>\n Original Source: https:\/\/futurism.com\/the-worlds-largest-and-most-powerful-x-ray-laser-just-went-online\/<\/p>\n Original Author: Dom Galeon<\/p>\n Original Date: Sept 5 2017<\/figure>\n","protected":false},"excerpt":{"rendered":"Molecular Snapshots<\/h2>\n
