| contents | Air shower array at the university of Puebla for the study of cosmic rays J. Cotzomi O. Martínez H. Salazar E. Moreno L. Villaseñor Física, Astronomía y Matemáticas Cosmic rays energy spectrum arrival direction We describe the design and performance of an extensive air shower detector array built in the Campus of the University of Puebla (locatedat 19◦N, 90◦W, 800 g/cm2) to measure the energy and arrival direction of primary cosmic rays with energies around 1015 eV, known asthe knee of the cosmic ray spectrum. The array consists of 18 liquid scintillator detectors (12 in the first stage), and 3 water Cherenkovdetectors (one of 10 m2 cross section and two smaller ones of 1.86 m2 cross section), distributed in a square grid with a detector spacing of20 m over an area of 4000 m2. In this paper, we discuss the calibration and stability of the array and report on preliminary measurementsof the arrival directions and energies of cosmic ray showers detected with the first stage of the array consisting of 12 liquid scintillator and 3 water Cherenkov detectors. Our results show that the array is efficient in detecting primary cosmic rays with energies in the range of 1014to 1016 eV, with an angular resolution lower than 5.5◦ for zenithal angles in the range of 20◦ to 60◦. We also point out that the capability ofwater Cherenkov detectors to separate electromagnetic from muon components of extensive air showers. Finally we remark that this facilityis also used to train students interested in the field of cosmic rays. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063707 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
