我们从基础和应用两个层面描述了天体粒子物理学的一些项目和倡议。为研究宇宙射线的各种特性和现象，设计、建造并投入使用了3台专用仪器。其中一种基于切伦科夫效应的探测器由三个水切伦科夫探测器组成，该探测器在空间和时间上进行了校准，可以表征宇宙射线粒子的次级级联。这些设备可以研究从地面探测到的二次粒子中产生的初级宇宙射线的原始成分和参数。第二种基于闪烁效应的探测器用于材料和山地结构表征的特定应用。这些探测器允许计数入射的二次粒子（主要是介子），同时确定它们的到达方向。通过研究它们在物质介质中的衰减，可以推断其组成和密度分布。
We describe some projects and initiatives for astroparticles physics from basic and application level. Three specialized instruments have been design, built and put into operation for the study of various characteristics and phenomena of cosmic rays. One of detector based on Cherenkov effect consists of three Water Cherenkov Detectors calibrated spatially and temporally, that allow the characterization of secondary cascades of cosmic ray particles. These devices allow to study the original composition and parameters of primary cosmic rays from the secondary particles detected on the ground. A second type of detectors based on scintillation effect are used for specific applications in the characterization of materials and mountainous structures. These detectors allow the counting of incident secondaries particles (muons mainly) while determining their arrival direction. Studing their attenuation in the material medium we can infer composition and density profiles.
