BELMONT-MORENO, E et al. Initial results of the mexican participation in the Alpha Magnetic Spectrometer Project. Rev. mex. fis. [online]. 2007, vol.53, suppl.3, pp.49-51. ISSN 0035-001X.

México is part of the AMS (Alpha Magnetic Spectrometer) project, consisting of several radiation detectors integrated in a single telescope to be sent to the outer space in search of antimatter. One of those detectors is a RICH (Ring Imaging Cherenkov), where the cosmic particle's speed is calculated from the Cherenkov light-rings observed. The IF-UNAM group works in characterizing the silica aerogel used as luminous element in this detector. Because the spectrometer will be in orbit for several years, some particular studies are necessary. Our group works on possible ageing mechanisms, showing that the main threat to this material is contamination rather than thermal, or vacuum, shocks.

Palabras llave : AMS; RICH; aerogel.
