Latest results from the PolarquEEEst missions
July 29, 2021
The PolarquEEEst scientific programme consists in a series of measurements of the cosmic ray flux up to the highest latitudes, well beyond the Polar Article Circle. It started in Summer 2018, when one telescope for cosmic rays was installed on a sailboat leaving from North Iceland,
to circumnavigate the Svalbard archipelago and land in Tromsø. It collected data up to 82N,
measuring with unprecedented precision the charged particle rate at sea level in these regions.
During Fall of the same year and Spring 2019 the PolarquEEEst programme continued with a
series of measurements performed using the same detector, which took place first in Italy, with
the southernmost point reached at Lampedusa, and then in Germany, with the goal to measure the
dependence of cosmic charged particle rate with latitude.
Then, in May 2019, the PolarquEEEst collaboration accomplished another important result, installing
a cosmic ray observatory for the detection of secondary cosmic muons at Ny Alesund, at
79N, made of three independent identical detectors positioned a few hundred meters from each
other, and synchronized in order to operate together as a network. This configuration allows high
precision measurements never performed before at these latitudes on a long term, also interesting
for their connection with environmental phenomena.
Here the various missions will be presented, and the latest results from the measurements performed will be shown.
