望远镜阵列低能量扩展（TALE）将由闪烁计数器和荧光望远镜阵列组成，旨在将望远镜阵列（TA）实验的最小能量降低大约一个数量级。荧光探测器将有 11 个望远镜，覆盖仰角 31 至 59 度，方位角 108 度。与现有TA表面阵列一样，将有45个400m间距的闪烁计数器、31个600m间距的闪烁计数器和37个1200m间距的闪烁计数器。 TALE 的物理目标是研究宇宙射线光谱的第二拐点和银河系-河外转变，并表征 10 eV 的宇宙射线簇射，以与等效质能中心的大型强子对撞机测量进行比较。
The Telescope Array Low Energy Extension (TALE) will consist of an array of scintillation counters and fluorescence telescopes designed to lower the minimum energy of the Telescope Array (TA) experiment by about an order of magnitude. The fluorescence detector will have 11 telescopes which cover elevation angles between 31 and 59 degrees, and 108 degrees in azimuth. There will be 45 scintillation counters with 400m spacing, 31 with 600m spacing, and 37 counters with the same 1200m spacing as the existing TA surface array. The physics aims of TALE are to study the second knee of the cosmic ray spectrum and the galactic-extragalactic transition, and to characterize cosmic ray showers at 10 eV to compare with LHC measurements at the equivalent center of mass energy.
