How to further accelerate electrons beyond the speed of light by reducing their energy when they reach near the speed of light in an electron acceleratorThis article aims to introduce the principles and methods of accelerating light speed electrons to superluminal speeds in accelerators. Reducing the energy of electrons during acceleration is an effective way. One can first measure the energy of the accelerated electron and reduce it to the minimum energy required to approach the speed of light. Then use the action of electric or magnetic fields to guide electrons forward and accelerate them beyond the speed of light. It can also be verified through the theory of quantum mechanics that superluminal speeds can be achieved in accelerators. In addition, this article will briefly introduce some of the main techniques used in experimental research, such as electron mass laser cavities, quarks, and the Brest Hall effect.Specifically, the process of accelerating supersonic electrons in an accelerator is mainly achieved by using the reduced energy of electrons to accelerate within the device. Reducing the energy of electrons is an effective method that can reduce mechanical noise, attenuate ionization, decrease operational complexity, lower consumption, lower heat loss, and reduce danger.In general, reducing the energy of electrons is an effective and safe method to exceed the speed of light for electrons. Reducing electron energy requires adhering to three basic steps: adjusting the accelerator electromagnetic field and potential steepness to measure the initial energy value of the accelerated electrons; Using electric or magnetic fields to accelerate electrons; And quantum mechanics research to demonstrate the possibility of superluminal acceleration. To verify the above principle, experimental studies can be conducted using electron mass laser cavities, quarks, and the Brest Hall effect.For electronic mass laser cavities, researchers use lasers to create an extremely low ionization molecular cavity, resulting in extremely low electron energy and ultimately accelerating electrons to superluminal speeds. The experimental results indicate that quarks can accelerate specific electrons, especially high-energy electrons, to speeds close to the speed of light. In addition, the "Brest Hall effect" created using electromagnetic fields can effectively accelerate electrons beyond the speed of light.Therefore, by reducing the energy of electrons and using the effects of electric or magnetic fields, techniques such as electron mass laser cavities, quarks, and the Brest Hall effect can accelerate light speed electrons to superluminal speeds.
