The goal of the PolarquEEEst experiment was to measure the cosmic charged particle rate at latitudes greater than 66\(^{\circ }\) N, where no systematic and accurate measurements at sea level have ever been performed. A latitude range well above the Arctic Circle was explored on board of a sailboat, up to the unprecedented northernmost value of \(82^{\circ }07^{\prime }\) N. In this paper a description of the experimental set-up is reported, then the procedures for calibration and data analysis are described in detail. The results show that the rate measured in this latitude range stays constant within a novel accuracy of \(\pm 1\)%.

利用PolarquEEEst实验，对北极圈外的宇宙带电粒子速率进行了新的高精度测量

所述PolarquEEEst实验的目的是测量在纬度宇宙带电粒子率超过66更大\（^ {\ CIRC} \） N，其中在海平面没有系统和精确的测量曾经被执行。在帆船上探索了一个位于北极圈上方的纬度范围，最高达到了\（82 ^ {\ circ} 07 ^ {\ prime} \） N的最北端的值。在本文中，对实验集进行了描述报告升级，然后详细描述校准和数据分析的过程。结果表明，在此纬度范围内测得的速率在\（\ pm 1 \）％的新精度内保持恒定。
