The Indian National Gamma Array (INGA) is set up at TIFR-BARC accelerator facility, as a part of a national collaboration between different research Institutes and Universities. The array is designed for 24 Compton suppressed clover detectors providing around 5% photo-peak efficiency. Recently, a digital data acquisition system with 96 channels (based on Pixie-16 modules developed by XIA LLC) has been implemented for this Compton suppressed clover array. The digital system provides higher throughput, better energy resolution and better stability for the multi-detector Compton suppressed clover array compared to its previous conventional system with analog shaping. A number of nuclear spectroscopic experiments have been carried out using the array. The results from the initial in-beam experiments of the complete set-up will be discussed in this paper.
