“…Fig. 1 (right panel) shows the expected antiproton measurement at the top of the atmosphere (TOA) for three ∼35 day antarctic flights at ∼37 km float altitude [7]. The GAPS precision measurement of antiprotons in this unexplored low-energy range will have about two orders of magnitude more low-energy antiprotons than BESS [12,13] and PAMELA [14] combined, i.e., ∼500 antiprotons expected for each flight.…”

“…GAPS will provide unprecedented sensitivity for antideuteron and antihelium nuclei [5,6]. Moreover, GAPS will perform high statistic measurements of antiprotons and extend the energy coverage in an unexplored low-energy region [7]. The GAPS sensitivity for cosmic antiproton spectrum (red) at the top of the atmosphere is shown with the statistics expected from three 35-day flights [7].…”

GAPS (General Anti-Particle Spectrometer) is a balloon-borne experiment designed to measure low-energy (<0.25 GeV/n) cosmic antinuclei (i.e., antiprotons, antideuterons, and antihelium nuclei) as a signature of dark matter annihilation or decay. According to viable beyond-the-Standard Model theories, the predicted dark matter signal in the low-energy antideuterons and antihelium nuclei channels is several orders of magnitude higher than the astrophysical background. The experiment will conduct a series of at least three long-duration balloon flights at high altitudes from Antarctica. The instrument is composed of a Si(Li) tracker surrounded by a Time-of-Flight system made of plastic scintillators. GAPS uses the novel exotic-atom detection technique in which an antinucleus is captured by the tracker material and forms an exotic atom. This excited exotic atom decays within the order of nanoseconds emitting X-rays at specific energies defined by the atomic transitions and annihilates emitting secondary particles (mainly pions and protons). The measured quantities (e.g., dE/dx, time of flight, annihilation vertex position, X-rays energies, etc.) allow for identifying antinuclei with high precision.

“…Thus, an error on the Cherenkov angle will directly lead to an equal error on the viewing angle and the neutrino direction. A 1% error in n corresponds to a 0.4 • error in the Cherenkov angle, which, at first glance, seems small compared to the several degrees angular resolution of RNO-G (Plaisier et al, 2021(Plaisier et al, , 2023.…”

“…Thanks to the large attenuation length of cold ice at radio frequencies (Aguilar et al, 2022a, c;Avva et al, 2015;Barrella et al, 2011;Hanson et al, 2015), a shower produced by a neutrino at energies above ∼ 10PeV can be observed over distances of several kilometers, making it possible to monitor several cubic kilometers with a small number of antennas, and achieve an effective volume large enough for UHE neutrinos. If the radio signal from a neutrino is detected, it is also possible to reconstruct the neutrino energy and direction from the radio signal (Aguilar et al, 2022b;Plaisier et al, 2023).…”

In situ, broadband measurement of the radio frequency attenuation length at Summit Station, Greenland

Over the last 25 years, radiowave detection of neutrino-generated signals, using cold polar ice as the neutrino target, has emerged as perhaps the most promising technique for detection of extragalactic ultra-high energy neutrinos (corresponding to neutrino energies in excess of 0.01 Joules, or 1017 electron volts). During the summer of 2021 and in tandem with the initial deployment of the Radio Neutrino Observatory in Greenland (RNO-G), we conducted radioglaciological measurements at Summit Station, Greenland to refine our understanding of the ice target. We report the result of one such measurement, the radio-frequency electric field attenuation length $L_\alpha$ . We find an approximately linear dependence of $L_\alpha$ on frequency with the best fit of the average field attenuation for the upper 1500 m of ice: $\langle L_\alpha \rangle = ( ( 1154 \pm 121) - ( 0.81 \pm 0.14) \, ( \nu /{\rm MHz}) ) \,{\rm m}$ for frequencies ν ∈ [145 − 350] MHz.
