After the LHC era super machine was unveiled: 1000 times more energy than global electricity

According to foreign media reports, the Large Hadron Collider (LHC) on the border of Geneva, Switzerland, is considered to be the world's largest particle accelerator. The 27-km-long acceleration track is laid underground, equipped with a proton synchrotron and super-proton synchronization. Accelerators (SPS), compact muon coils (CMS), and ATLAS instruments. Currently, the Large Hadron Collider is undergoing energy upgrades so that collision experiments can be continued in the future. At the same time, scientists have recently proposed supercomputers to replace the Large Hadron Collider, which is considered to be the collider of the post-LHC era and uses a revolutionary laser system to develop a new generation of particle accelerators.

Scientists believe that the new particle collider will use advanced laser technology and can instantaneously output energy that can exceed the global power by a factor of 1,000

Inspired by coherent amplification network technology, scientists believe that the use of laser technology can generate intense monochromatic light beams and constitute large-scale fiber laser arrays. Research based on this new technology has been performed in the CERN laboratory and has been applied more. Proton therapy is an advanced cancer treatment technology for proton therapy and nuclear chemistry experiments. This study has been published in the journal Nature Photonics. Scientists believe that lasers can provide powerful energy exposure in a very short period of time. After maturing the technology, the energy that is excited in an extremely short time is 1000 orders of magnitude of the global production capacity. Therefore, a large-scale collider based on laser technology will It is an advanced particle accelerator that will replace LHC in the future.

The advanced compact particle accelerator has broad application prospects. It can be used not only for particle physics experiments, but also for the development of new drugs. For example, proton therapy, one of the most advanced cancer treatment technologies, can also reduce the use of radioactive substances on the ecological environment. Destruction, radioactive contamination of traditional nuclear materials may affect tens of thousands of years. Currently, there are two major bottlenecks that hinder the development of high-intensity laser technology. First, conventional laser technology can only form one laser pulse per second, and if the technology is applied to the actual situation, it will need to be generated every second. Tens of thousands of laser pulses. Secondly, the "efficiency" of current super lasers is very low. The output energy only occupies a small part of the input energy. The particle collision requires that the output power reach the megawatt level, so it cannot be produced under the current low output energy. Reaching design experiment requirements is almost impossible in the economy.

In response to this, under the auspices of the relevant EU consortium, the world's top 12 laboratories such as the Optoelectronics Research Center of the University of Southampton, the University of Jena, Germany, and the European Nuclear Research Center began research on high-energy repetitive laser pulse sources in order to increase Fiber laser efficiency and controllability. High-energy physics research requires large accelerators, which are almost a few kilometers in size. It takes billions of euros to build such an accelerator. Therefore, how to reduce the size and cost of the acceleration device and achieve the same experimental purpose is to future high-energy physics The key to learning research.

Dr. Brock Brooks of the Optoelectronics Research Center in Southampton believes that a typical future high-energy physics research facility will require the use of thousands of optical fibers, each group of fibers carrying part of the laser energy, so that a powerful output power can be generated. It also provides a larger surface cooling area for multiple repetitive operations. Preliminary proof of concept shows that current technological developments can control thousands of laser fibers, accelerating electrons to several GeVs (10ths of 9th electron volts). Therefore, the technology adopted by the large-scale collider in the future will be revolutionary. After overcoming problems such as output power and materials, the particle colliding experiment will reach a new height.
