Description

technical field [0001] The invention relates to the technical field of ion acceleration and the field of nuclear physics, in particular to a neutrino beam generating device based on a laser accelerator. Background technique [0002] Neutrinos have very little interaction with matter, and lose little energy when passing through matter, and can penetrate the earth, so they can be used for neutrino communication, realizing any connection between two points on the earth, etc. Neutrino communication can break through the forbidden areas of underwater and underground electromagnetic wave communication, and realize global communication. Because it is not easy to intercept, has almost no attenuation, and is not afraid of external interference, neutrino communication has great potential in terms of national security and civilian needs. Wide application prospects. The prerequisite for the wide application of neutrinos is to be able to obtain a neutrino source with controllable energy...

AI Technical Summary

Problems solved by technology

At the same time, in the practical application of neutrino communication, the transmission direction of the neutrino beam needs to be changed in real time according to the target position of the received signal, which cannot be realized in traditional accelerators, because traditional accelerators use magnets to control protons. The transmission of the beam, the direction and position of the proton beam are difficult to change

In addition, for a traditional accelerator that has been built, its proton energy is a single energy and basically cannot be changed, so the corresponding neutrino energy generated is also fixed, which cannot meet the application requirements of neutrinos with different energies

To sum up, neutrino beam sources driven by traditional radio frequency accelerators have great limitations in practical applications
