内容記述 |
A multi-directional muon telescope having an area of 8m² was constructed in a tunnel with a vertical depth of approximately 50 m. w. e. at Matsumoto. Continuous measurements of cosmic-ray intensity have been made since April 7, 1971. A preliminary report is presented concerning the underground site, experimental apparatus, and its arrangement, as well as some examples of experimental data obtained, and analyzed results of cosmic-ray daily variation. Counting-rates are 6 x 10⁴/hr of vertical component for 8 m² area at a depth of ～50 m. w. e., and 3.4 x 10⁴ /hr of N-component at ～42 m. w. e., 0.85 x 10⁴ /hr of S-component at ～92 m. w. e. for each of 6 m² area, 1. 1 x 10⁴ /hr of E-component at ～65 m. w. e., and 1. 55 x 10⁴ /hr of W-component at ～53 m.w.e. for each of 4m² area, inclined at 40° to the vertical. It is found that the observed phases of diurnal and semidiurnal vectors for five components are indicative of the extraterrestrial nature of the daily variation. The observation thus may provide an important information on the modulation of cosmic-ray intensity variation. |
