Radio waves recognize particles showers on plastic blocks, When neutrinos break down into water molecules in more than one billion tons of ice that forms a detector at the IceCube Neutrino Observatory in Antarctica.

More than 5,000 sensors capture light from subatomic particles generated from collisions. But as you might guess, this big experiment isn’t cheap.

The researchers beamed electron rays, deflected by a coherent Linac light source (LCLS) SLAC, into large blocks of plastic to simulate neutrino collisions with ice. Radio waves recognize particles showers on plastic blocks.

When interacting neutrally with ice, it creates a cascade of high-energy particles that leave traces of ionization. The same applies to electronic collisions in plastics.

To identify this ionization pathway, the team used an antenna to reflect radio waves from it.

This radar produces echoes that are triggered by additional antennas. This is the first time researchers have been able to detect radar echoes from a particle cascade.

This echo contains neutrinos information in the energy range that can bridge the gap between low energy neutrinos detected by IceCube and high energy neutrinos detected by ice detectors and other bubbles. To continue, the researchers hope to use a similar arrangement to detect radioecho-neutrinos in Antarctic ice. Radio waves recognize particles showers on plastic blocks.

If successful, this technology could eventually enable researchers to expand the IceCube energy without damaging the bank.
