南极的冰立方中微子天文台通过研究用IceTop和冰中探测器测量的空气簇射的Muonic和电磁成分，探测高能宇宙线天空。然而，要了解高能宇宙线天空的天体物理学，还需要更详细的测量。这一点，再加上减轻积雪对冰顶储罐的影响的需要，推动了我们进一步升级，包括闪烁体和基于SiPM读数的站。展示下一代宇宙线探测技术进步的原型站目前正在建设中，将于2017年12月在南极部署。我们描述了该项目的物理和现状。
The IceCube Neutrino Observatory at the South Pole probes the high-energy cosmic-ray sky by investigating the muonic and electromagnetic component of air showers measured with IceTop and the in-ice detector. However, more detailed measurements are needed to understand the astrophysics of the high-energy cosmic-ray sky. This, along with the need to mitigate the impact of snow accumulation on IceTop tanks, has given us impetus for further upgrades including scintillator and SiPM-readout-based stations. Prototype stations showcasing technological advances for the next generation in cosmic ray detection are currently under construction for deployment at South Pole in December 2017. We describe the physics and the current status of the project.
