Abstract : 21m diameter MACE (Major Atmospheric Cherenkov Experiment) is being setup at a high altitude (4270m asl) astronomical site Hanle. The telescope will deploy a Photo-Multiplier Tube (PMT) based 1088-pixel imaging camera at its focal plane. In-house developed camera has been designed as a modular structure comprising 68 Camera Integrated Modules (CIM), each of which houses 16 PMTs along with signal processing electronics. A prototype camera comprising 4 CIMs (64 pixels) has been developed to characterize the operating parameters e.g high voltage, anode current, single channel rate etc. and evaluate the performance of the imaging camera in terms of stability of these parameters with time and GHz signal digitization using Domino Ring Sampler. The prototype camera has been extensively tested at ECIL, Hyderabad, under simulated light conditions using pulsed and DC LEDs to resemble the Cherenkov pulse and night sky background. The results of the performance evaluation of the 4CIM camera will be presented in this meeting.
