A large mystery that is currently being investigated by the High Energy Physics (HEP) field is the origin and the nature of the Ultra-high energy Cosmic Rays (UHECR). Coming from deep within the Universe, they interact with Earth’s atmosphere and multiply from a single particle with enormous energy to billions of particles with much lower energy, causing what scientists call Extensive Atmosphere Showers (EAS). Another current challenge in HEP and science in general is raising and training new generations of capable scientists to investigate the current mysteries and discover new ones. The shape of the EAS when it reaches the planet’s surface is a disk of varying thickness, similar to magnifying glass – thicker in the center and tapering towards the edges. The main goal of this proposal is to develop a fast-speed detector system that is capable of recording cosmic ray events, digitized at high speed. From that data, the information of the disk thickness can be studied for the purpose of improving current EAS simulation software as well as developing and improving the existing methods for analyzing the data so that we can tell the origin of the particle, its energy, and its species (i.e., was it a neutron, a proton, or a nucleus of some element). Additionally, the capabilities of the detector will assist in the search for the new types of the EAS, such as Cosmic Ray Ensembles proposed by CREDO collaboration, and in the confirmation of the Unusual Events that were observed by the Horizon-T collaboration. Participation of undergraduate students in these activities with support and supervision will provide the training for the future scientists using the real experiment in multiple topics will provide hands-on research experience for a diverse student population supporting the groups underrepresented in the Mathematical and Physical Sciences.The intent of this proposal is to initiate the scalable research project in physics that can be subsequently extended. The project goal will be the development, design and construction and deployment of core modules of DUCK (Detector system of Unusual Cosmic-ray casKades). The main scientific importance for the DUCK project will be adding the capabilities of the high-speed full wavelength recording of the EAS events with different trigger possibilities, analysis of which would contribute: to general EAS event analysis methodology using the full waveform and detector response width, to CORSIKA simulation development and check of the current and upcoming versions (7 and 8), to the overall cosmic ray flux and space weather monitoring, to the search for the Cosmic Ray Ensembles by CREDO collaboration, and to an independent verification of the detection of the ‘unusual’ cosmic ray events by the Horizon-T detector system. The project will involve computer simulation activities, design and construction, data acquisition system design, data collection and analysis, allowing participation of students pursuing not only physics but also other STEM fields, such as Chemistry, Engineering and Computer Science. The project will extend the research potential and facilities at Clayton State University (CSU). This would serve as strong institutional support and encouragement of first-generation college students for whom there is often little family support for going to graduate schools after graduation from CSU.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

高能物理（HEP）领域目前正在研究的一个大谜团是超高能量宇宙射线（UHECR）的起源和性质。它们来自宇宙深处，与地球大气层相互作用，从一个具有巨大能量的单个粒子繁殖到数十亿个能量低得多的粒子，造成科学家所谓的广泛大气阵雨（EAS）。HEP和整个科学目前面临的另一个挑战是培养和训练新一代有能力的科学家来调查当前的奥秘并发现新的奥秘。当EAS到达行星表面时，它的形状是一个不同厚度的圆盘，类似于放大镜——中心较厚，边缘逐渐变细。该提案的主要目标是开发一种能够记录宇宙射线事件并高速数字化的快速探测器系统。从这些数据中，可以研究磁盘厚度的信息，以改进当前的EAS模拟软件，并开发和改进现有的数据分析方法，以便我们可以告诉粒子的起源，它的能量，它的种类（即，它是中子，质子，还是某种元素的原子核）。此外，探测器的能力将有助于寻找新的EAS类型，例如CREDO合作提出的宇宙射线集合，以及确认地平线- t合作观测到的不寻常事件。本科生在支持和监督下参与这些活动，将为未来的科学家提供培训，使用多个主题的真实实验，为不同的学生群体提供实践研究经验，支持数学和物理科学中代表性不足的群体。本提案的目的是启动可扩展的物理研究项目，该项目可随后扩展。该项目的目标是开发、设计、建造和部署DUCK（异常宇宙射线级联探测系统）的核心模块。DUCK项目的主要科学意义在于增加对具有不同触发可能性的EAS事件进行高速全波长记录的能力，对其进行分析将有助于：到使用完整波形和探测器响应宽度的一般EAS事件分析方法，到CORSIKA模拟开发和当前和即将发布的版本（7和8）的检查，到整体宇宙射线通量和空间天气监测，到由CREDO合作寻找宇宙射线合奏，以及对地平线- t探测器系统探测到的“不寻常”宇宙射线事件的独立验证。该项目将涉及计算机模拟活动、设计和建造、数据采集系统设计、数据收集和分析，让学生不仅可以参与物理，还可以参与其他STEM领域，如化学、工程和计算机科学。该项目将扩大克莱顿州立大学（CSU）的研究潜力和设施。这将为第一代大学生提供强有力的制度支持和鼓励，因为他们从科罗拉多州立大学毕业后，通常没有什么家庭支持去读研究生。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
