The LED calibration system of the IceCube Upgrade — •Martin Rongen for the IceCube collaboration — Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-Universität Erlangen Nürnberg
The IceCube Neutrino Observatory, instrumenting about 1 km3 of deep, glacial ice at the geographic South Pole, is due to be enhanced with the IceCube Upgrade. The IceCube Upgrade will be deployed during the 2025/26 Antarctic Summer season, consisting of seven new columns of photo sensors. It targets neutrino oscillations and improvements to the calibration of the optical properties of the instrumented ice, thereby improving the angular and energy resolution of archival and new neutrino events. For this purpose, the Upgrade will include a host of new calibration devices. These include several thousand pulsed LEDs incorporated into the photosensor modules. The array of LEDs and photo sensors will allow us to improve our knowledge on the light propagation in the instrumented ice. Here, we describe the design and production of this LED system as well as testing prior to integration into the sensor modules.
