Electrons Accelerated Up to 99.9999999985 Of Light Speed
In a beam line established at the MAX IV Laboratory in Sweden, electrons bring the speed of light closer. With this ability, the beam line can lead to many experiments.
Scientists from Finland and scientists from the University of Tartu in Estonia established a light line at the Swedish National Max IV Laboratory in Lund, Sweden. Research for the so-called FinEstBeAMS started in late 2018. The project is one of the few studies carried out by Estonia abroad. FinEstBeAms, which cost around 7 million euros, was the first beam line in the MAX IV Laboratory, which was completed by international cooperation.
Physicists from the University of Tartu experimented with Finnish scientists, who had previously worked for the design, construction and operation of the beam line. The results of the experiments were announced to the scientific world with the article. The article describing the results of the experiment was published in the Journal of Molecular Liquids.
In this study, complex electronic structures of [EMIM] [TFSI], [DEME] [TFSI] and [PYR1,4] [TFSI] ionic liquids in a gaseous phase were examined using photoelectron spectroscopy. Ionic liquids are essentially dissolved salts present in the liquid phase at room temperature. One of the most advanced applications of ionic liquids is their use in supercapacitors instead of conventional electrolytes.
Supercapacitors can store a large amount of energy and deliver enormous electrical power in a short time. Whether or not some ionic liquids are more suitable than other liquids used as electrolytes in supercapacitors has yet to be determined.
In order to understand the application potentials of ionic liquids, to model and calculate their properties, it is necessary to reveal their electronic structures by using the latest experimental methods. A basic understanding of the electronic structures of ionic liquids helps to uncover the main factors affecting the properties of various ionic liquids.
Vambola Kisand, president of the UT Institute of Physics X-ray Spectroscopy Laboratory, said: “The beam line surprised us with the intense photon flow that allowed the studies to be performed with extremely good spectral resolution and short data collection times. The quality data obtained provides a perfect comparison. It helped confirm the theoretical results obtained by modeling the properties of ionic liquids conducted by our research group. Gr
MAX IV is a circular accelerator called synchrotron. The accelerator emits bright shortwave radiation, which allows a plurality of electron beams circulating therefrom to reveal the internal structure of the material under investigation, for example biological molecules or nano-sized materials. The accelerator is also suitable for investigating the properties of the electronic structure and various substances.
In the MAX IV accelerator, in a stainless steel tube one centimeter in diameter, the ultra high vacuum electron beams are accelerated up to 99.9999999985 of the speed of light on a 528-meter storage ring. The light emitted from electrons leştiril domesticated tarafından by the magnetic field is directed to the beam lines with various ends where the final experiments are performed. MAX IV is currently one of the most modern synchrotrons in the world and one of the brightest light sources.
Synchrotron is designed to be used by many people from the work of university research groups to the activities of entrepreneurs. The MAX IV Laboratory, which has been in operation since 2018, has six beam lines and 500 users to date. With a few light lines to be installed, the number of users of the laboratory is expected to increase to around 2500.
The European Spalling Source (ESS), which also offers neutrons for research, is established next to the MAX IV Laboratory. When established at ESS, MAX IV and ESS will be one of the largest research centers in Northern Europe in collaboration with experiments.
The MAX IV beam line can provide photons covering energy ranges ranging from 5 to 1,400 eV. FinEstBeAMS offers high-quality short-wave VUV-XUV radiation as well as high-tech companies for the deposition of electronic structures of a single atom, molecules, clusters and nanoparticles on the gaseous surfaces, as well as on the surfaces.
The capabilities of the MAX IV Laboratory have been used to date by Estonian companies such as Clifton and Lumifor. Clifton analyzed the properties of new semiconductor materials for microelectronics. Lumifor worked on new dosimetric materials to develop more efficient radiation detectors used to monitor the radiation levels of medical radiographs to measure ionizing radiation in the environment.
