Abstract
The Non-Imaging CHErenkov Array (NICHE) is a low energy extension to Telescope Array and TALE using an array of closely spaced (~200 m) light collectors covering an area of ~2 square km. It is being deployed in the field of view of TALE and will overlap it in the energy range above 4 PeV. Cosmic ray air showers with energies 1-100 PeV will be reconstructed using both the Cherenkov light Lateral Distribution and the Cherenkov time Width Lateral Distribution. These two methods will allow shower energy and $X_\mathrm{max}$ to be determined. A prototype of the array, called j-NICHE, has been deployed. Firstly mentioning the performance of detector's component, current status of the detectors and the observations will be presented.
