It has specific applications in server environments, storage solutions, and high-performance computing where rapid data access and transfer are crucial.

The SND experiment, or the Stereo Neutrino Detector experiment, is a particle physics experiment designed to study neutrinos, which are elusive subatomic particles that interact very weakly with matter. Launched in 2020, the SND experiment is located at the Russian neutrino research facility known as the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow.

SNO+ (SNO Plus) is a neutrino experiment that is an upgrade of the original Sudbury Neutrino Observatory (SNO) in Canada. The SNO experiment primarily aimed to study neutrinos produced by the fusion reactions in the Sun, providing crucial insights into solar physics and neutrino properties.

The STAR (Solenoidal Tracker at RHIC) detector is a particle physics experiment located at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in New York. It is designed to study the properties of quark-gluon plasma, a state of matter believed to have existed shortly after the Big Bang when quarks and gluons were not confined within protons and neutrons.

The STEREO (Solar TErrestrial RElations Observatory) experiment is a NASA mission designed to study the Sun and its effects on the Earth and the surrounding space environment. Launched on October 25, 2006, STEREO consists of two identical spacecraft, STEREO-A (Ahead) and STEREO-B (Behind), which are positioned at different points in their orbits around the Sun.

Scattering is a physical process in which particles or waves (such as photons, electrons, neutrinos, etc.) deviate from their original trajectory due to interactions with other particles or fields. In the context of particle physics, scattering can refer to interactions between subatomic particles, often leading to the production of new particles or changes in the energy and momentum of the incoming particles. Scattering processes are fundamental in understanding the fundamental forces of nature and the interactions between particles.
