摘要
A module of the NESTOR underwater neutrino telescope was deployed at a depth of 3800 m in order to test the overall detector performance and particularly that of the data acquisition systems. A prolonged period of running under stable operating conditions made it possible to measure the cosmic ray muon flux, I-0 (.) cos(alpha)(theta), as a function of the zenith angle theta. Measured values of index alpha and the vertical intensity I-0 (Graphics) are in good agreement with previous measurements and phenomenological predictions. (c) 2005 Elsevier B.V. All rights reserved.
