TA和奥格最近的观测提高了我们对超高能量宇宙射线的理解，但它们的起源仍然不清楚。在未来，通过观察更大的统计量来获得定向能谱和成分分布将是一种有效的方法，并且对未来的大规模实验有积极的讨论。为了实现如此巨大的观测面积，宇宙射线空气荧光菲涅耳透镜望远镜（craft）项目已经开始研制具有成本效益的菲涅耳透镜荧光望远镜。我们利用原型望远镜与TA同步观测，成功地观测到了宇宙射线引起的空气阵雨。我们目前正在开发一种使用波形的事件重建方法，优化焦平面，开发校准系统，并开发用于未来大规模部署的自主观测系统。讨论了该项目的现状和未来发展前景。
Recent observations by TA and Auger have advanced our understanding of ultra-high energy cosmic rays, but their origin is still unclear. As a future approach, it will be effective to obtain the directional energy spectra and compositional distributions by observing even larger statistics, and there are active discussions on future large-scale experiments. In order to realize such a huge observation area, the Cosmic Ray Air Fluorescence Fresnel lens Telescope (CRAFFT) project has started to develop a cost-effective fluorescence telescope with Fresnel lenses. We have succeeded in observing cosmic ray induced air showers by simultaneous observations with TA using prototype telescope. We are currently working on the development of an event reconstruction method using waveforms, optimization of the focal plane, development of a calibration system, and development of an autonomous observation system for future large-scale deployment. The current status and future prospects of the CRAFFT project are discussed.
