TL;DR
The Tunka-133 array, operational since 2006, is a large-scale Cherenkov detector designed to study cosmic rays' energy spectrum and composition in the 10^15 to 10^18 eV range using a novel method.
Contribution
This paper reports the development and initial deployment of the Tunka-133 array, a new large-area Cherenkov detector for cosmic ray research.
Findings
First cluster operational since October 2006
Preliminary data acquisition results obtained
Array design enables detailed cosmic ray studies
Abstract
The new EAS Cherenkov array Tunka-133, with about 1 km**2 sensitive area, is being installed in the Tunka Valley since the end of 2005. This array will permit a detailed study of the cosmic ray energy spectrum and the mass composition in the energy range of 10**15-10**18 eV with a unique method. The array will consist of 19 clusters, each composed of 7 optical detectors. The first cluster started operation in October 2006. We describe the data acquisition system and present preliminary results from data taken with the first cluster.
