Abstract

Scintillator detector have been used in a wide range of experiments in different areas: Nuclear and High Energy Physics, Medicine, and Radiation Security among others. It is common to use scintillator counters coupled to Photomultiplier Tubes (PMT) as a read out detectors. Nowadays, there has been a great interest in using the Silicon Photomultipliers (PMSi) as a replacement for PMT's due to their high photon detection efficiency (PDE) and their high single photon time resolution (SPTR). The fast the signal is detected, the whole detection system will be useful to search for new physics. PMSi is also known to have a good compactness, magnetic field resistance and low cost. In our lab we are measuring the time resolution of two different models of PMS in order to build a fast radiation detector system.

Abstract 
The pyramid of Cholula was built at the beginning of 100 B.C. and during of period of 500 years it was finished, had several new constructions, based on the previous constructions. The primarily material of construction is the adobe. Early in 1931 archaeological excavations began with the intention of exploring the interior of the pyramid, excavations were stopped in 1971, and to date no further excavations have been carried out. This work shows the first measurements of muons, particles that are very penetrating, these are generated by primary cosmic rays that was incoming in the atmosphere and these generates a rain of secondary particles, among them the muons. To measure this kind of particles was implemented a detector system, it is formed by a scintillator plastic coupled to a tube photomultiplier; the signals were acquired by mean of an oscilloscope. The detector was collocated near of the center of the pyramid; the location belongs to the maxima concentration in mass over the detector. Graphs of the charge distribution, maximum amplitude and characteristic rise times of the generated pulses in a plastic scintillator are shown, this is scintillator was synthesized in the materials laboratory of the FCFM-BUAP. In addition the optical characterization of the same was realized.
