Status of the AMANDA South Pole Neutrino Detector

TL;DR

The paper reports on the progress and capabilities of the AMANDA South Pole Neutrino Detector, highlighting ice's transparency and the detector's ability to measure neutrino energy and bursts, with plans for expansion.

Contribution

It presents the initial deployment results, demonstrates the detector's multi-purpose measurements, and discusses future plans for a larger neutrino observatory in polar ice.

Findings

Deep polar ice is highly transparent for optical detection.

The detector can measure neutrino energy and supernova bursts.

Plans for expanding to a kilometer-scale detector are underway.

Abstract

Initial deployment of optical modules near 1 and 2 kilometer depth indicate that deep polar ice is the most transparent known natural solid. Experience with early data has revealed that a detector, conceived to measure muons tracks, can also measure energy of high energy neutrinos as well as bursts of MeV neutrinos, e.g. produced by supernovae and gamma ray bursts. We plan to complete AMANDA this austral summer to form a detector of 11 deep strings instrumented over 400 meters height with 300 optical modules. We will argue that ice is the ideal medium to deploy a future kilometer-scale detector and discuss the first deployment of 10 strings of kilometer length.
