Presentation description

The IceCube observatory searches for cosmological neutrinos by instrumenting 1 cubic kilometer of ice at the south pole. Hundreds of large spherical photomultiplier tubes search for traces of the ghost-like neutrinos. As a part of the IceCube Gen2 expansion, a Surface Array Expansion (SAE) would add an array of scintillator detectors and radio detectors on the ice surface above the in-ice neutrino detectors.

The primary purpose of these is to detect muons and other particles resulting from a cosmic ray induced air shower which could contaminate the neutrino signal. The array will also allow the study of these high energy cosmic ray events. To better understand the performance of these new detectors, we have embedded a full sub-array (8 scintillators on a 72 meter-spacing equilateral triangle and 3 radio detectors) within the Telescope Array's Low Energy (TALE) infill scintillator array, which is a well understood array of 50 scintillator detectors on a 100 meter-spacing square grid complemented by fluorescence telescope observations. We analyze SAE detector data through calibration, time-matching, and filtering, and compare lateral distribution flux results with TALE infill data.
