Description

A fundamentally new tool for studying the Cherenkov light emission from EAS based on a slit camera, a Cherenkov differential detector (CDD), was created on the Yakutsk complex EAS array. Several these detectors were placed around the center of the array. Arranged in such a way, they operate as a part of a the main array and their data can be used for reconstruction of air shower arrival direction and geometry. The photomosaic of a CDD consists of 10 photomultiplier tubes, each observing a certain region of the sky through a narrow slit in the roof of a detector housing. In the photomosaic plane the longitudinal development of a shower is represented as a series of photomultipliers with varying amplitudes. The important feature of CDD is the ability to determine the spatio-temporal picture of the development of the Cherenkov component of EAS in the atmosphere.
