We plan to leave Berkeley on November 28th, and fly via
The prototype is one step toward ARIANNA, a proposed array of about 10,000 stations, covering roughly 900 square kilometers. Each station will consist of 8 TV-like antennae embedded in the ice, connected to an electronics box containing trigger electronic and waveform digitizers. The whole thing will be powered by solar panels in the summer (when the sun is continuously above the horizon). For the winter, we are testing a wind generator, but this will place stringent limits on station power consumption.
The ARIANNA detectors search for radio waves produced by neutrino interactions in the ice. The radio pulses come from the particle showers produced when occur when the neutrino converts it’s energy into matter, creating a shower containing up to a trillion particles. The showers contain more electrons than positrons (because some of the photons
We use these neutrinos to probe the high energy cosmos, to find the origin of the high energy cosmic rays that have been observed by surface air shower arrays like Auger. ARIANNA will complement smaller neutrino detectors like the 1 cubic-kilometer IceCube array which is optimized for lower energy (10^11 to 10^17 eV) neutrinos.
