An Acoustic Calibration System for the IceCube Upgrade

Understand

The IceCube Neutrino Observatory will be upgraded with about 700 additional optical sensor modules and new calibration devices.

• Particularly, improved calibration will enhance IceCube's physics capabilities both at low and high neutrino energies.
• An important ingredient for a good angular resolution of the observatory is a precise calibration of the positions of optical sensors.
• We present the concept of newly developed acoustic sensors that are mounted inside the optical modules and additional acoustic emitter modules that are attached to the strings.
