摘要：
A search for cold dark matter has been carried out at the Canfrane Underground Laboratory with a set of three sodium iodide scintillators of 10.7 kg each, during two years of data taking. The results, corresponding to an exposure of 4613.6 kg day are presented in the form of exclusion plots sigma(m) for spin-independent and spin-dependent WIMP-matter interacions, by conventionally comparing the observed rate with the expected signal. Distinctive features of the CDM signal, like annual and daily modulations have been looked for, in, respectively, 1342.85 kg day and 2769.6 kg day of data. The non observance of such modulations have been used to draw stringer exclusion plots than those derived from the previous, conventional method.
