German scientists wrote in the latest issue of the journal Physical Review that their laser plasma accelerator lux produced electron beams continuously for more than one day for the first time, reaching 30 hours, a world record < / P > < p > lux was jointly developed and operated by desy and the University of Hamburg. In a laser plasma accelerator, a laser or high-energy particle beam generates plasma waves in microtubules, the researchers explained. A plasma is a gas in which the gas molecules are stripped of electrons. Lux uses hydrogen as a gas. “The laser pulse passes through the gas in the form of a narrow disk, in which the electrons are stripped from the hydrogen molecule, and the electrons immediately after the pulse are accelerated by a positively charged plasma wave in front of it,” explains Andreas Mayer, the team leader. As a result, the acceleration intensity of laser plasma accelerator is 1000 times higher than that of the most powerful machine. The more compact and powerful plasma accelerator is expected to be widely used in basic research, medicine and other fields < / P > < p > in record breaking uninterrupted operation, the accelerator can accelerate more than 100000 electron beams per second. With such a large data set, scientists can more accurately correlate and analyze the characteristics of accelerators, lasers and beams. “For example, we can trace unexpected changes in the electron beam to a specific location in the laser, so we know exactly where to start to produce a better beam of particles,” Meier said < p > < p > Meyer points out: “the system can run longer, but we stop running after 30 hours. The latest research has laid a solid foundation for the stable operation of this innovative particle accelerator technology, and the time is ripe to transfer laser plasma acceleration technology from the laboratory to practical application < p > < p > Meyer also stressed that there are still many technical challenges to overcome before putting these devices into practical use, “but now, we are able to operate the electron beam line for a longer time, which enables us to better meet these challenges.” “This work shows that the laser plasma accelerator can produce controllable output, which provides a solid foundation for further development of the technology,” concluded Wilm limans, head of desy accelerator department Compared with the traditional particle accelerators such as the Large Hadron Collider, the laser plasma accelerator accelerates particles in a completely different way. In recent years, traditional particle accelerators have been upgraded, and laser plasma accelerators have made new breakthroughs. A few years ago, the U.S. scientific research team accelerated the particles in a 9 cm long plasma tube, making it obtain an acceleration of more than 1000 times the energy gradient of the traditional particle accelerator, setting a new record for the laser plasma accelerator at that time. The new record will further promote the laser plasma acceleration technology out of the laboratory and into practical application.
