Different kinds of strong magnets play one of the major aspects of modern Physics. The magnetic fields they generate maintain the plasma within the chambers of thermonuclear experiments thanks to their help, particles flow are speeded up and directed in the tunnels of accelerators, and so on. However, not all electro strong magnets have the same characteristics that researchers and engineers from Fermi National Laboratory have developed an electromagnet that is superconducting, more powerful than anything that has been previously created in this direction.
For installations like the Large Hadron Collider, which is the most advanced particle accelerator available to date, strong magnets must produce a field that is at eight Tesla. The power output of the magnetic from the operating mode to the magnet occurs in a smooth manner at 0.006 Tesla per second, and can take up to 20 minutes. The magnetic field can be more swift when using particle accelerators with copper-wound powerful magnets. For example, the strong magnets used in the Japanese accelerator J-PARC that generate the highest-quality neutron flux, are capable of increasing the strength of the field at the rate of 70 Tesla per second. Similarly, the magnets that are strong of the Fermi laboratory accelerator can be used at the rate of 30 Tesla per second.
One of the difficulties that makes it difficult to increase the field of superconducting strong magnets at a high speed is the appearance of “hot spots” within the windings, the size of which grows as the current increases and generates a magnetic field. The temperature in the hot spots increases rapidly when current is increased. This means that the magnet’s performance is impaired or ceases to work.
Scientists from the Fermi laboratory have found an answer in the form of the material YBCO A complex mixture made up of barium, yttrium oxygen and copper. This is known as a high-temperature superconductor. magnet windings, that can operate at temperatures of up to 20 Kelvin were constructed from this substance. They can supporting currents as high as 1000 amps.
Tests on the first prototype of a high-temperature electromagnet showed that it could provide speeds of around 290 Tesla per second at a maximum magnetic field of 0.5 Tesla. Of course, a magnetic field strength is not the 8 Tesla required for particle accelerators. However, scientists are confident that they have the ability to further increase the current through the powerful magnets and, in turn to increase the strength of the magnetic field produced.The Fermi Laboratory continues to test with its new technology. Magnet The test involves evaluating different modes of operation and enhancing the used power source. Maybe in the future, similar Strong magnets New experimental facilities will have them , such as neutrino detectors and the next generation collider having an 100-kilometer radius of the Future Circular Collider.
