Fundamental questions that ask about the nature and the fate of the Universe are of interest not only to astronomers, but also to the general public. In particular, the realisation that the Universe is dominated by dark energy has sparked wide public interest. We still know very little about dark energy. Is it Einstein's famous cosmological constant or something more exotic, such as a new particle or even new physics? This proposal aims to build a sample of very distant galaxy clusters that can then be used to search for a very special type of supernova - the Type Ia Supernova, which can be used as a tool to learn about the properties of dark energy.

关于宇宙的性质和命运的基本问题不仅对天文学家感兴趣，而且对公众也感兴趣。特别是，认识到宇宙是由暗能量主导的，引起了公众的广泛兴趣。我们对暗能量知之甚少。它是爱因斯坦著名的宇宙常数，还是更奇特的东西，比如一种新的粒子，甚至是新的物理学？这项提议旨在建立一个非常遥远的星系团样本，然后可以用来搜索一种非常特殊的超新星-Ia型超新星，它可以作为一种工具来了解暗能量的性质。
