The three detector tubes of the South Pole neutron monitor
are on a platform in insulated, heated boxes. Data collection
electronics is in "Skylab," the tall boxy building behind.
Despite its small size, the South Pole neutron monitor
is the world's most sensitive detector of relativistic solar
cosmic rays, owing to its location at high latitude and high
altitude (2820 meters or 9252 feet). In a real sense, it is
closer to outer space than any other monitor on Earth. Photo
