Description
PINGU, the Precision IceCube Next Generation Upgrade, aims at lowering
the neutrino detection threshold of the IceCube neutrino telescope to a
few GeV by adding new in-fill strings to the existing IceCube/DeepCore
array. The main goal of the upgrade is to render the detector sensitive
to the neutrino mass hierarchy utilizing atmospheric neutrinos. Precision
reconstruction of neutrino direction and energy, which is a prerequisite
for the determination of the mass hierarchy, requires accurate in-situ
calibration and monitoring of the PINGU digital optical modules and
high-level control of systematic effects like those caused by
uncertaintiesin the optical ice properties and DOM sensitivity in ice.
The talk presents the current status of calibration studies for PINGU.
