摘要

A 12 layered 1 m \(\times \) 1 m Cosmic Muon tracker, based on Resistive Plate Chamber (RPC) has been operational in TIFR. An in-house developed Data Acquisition (DAQ) chain have been configured to collect data using a VME backend. During the long-term operation, we have observed sudden electronic noise pick-up in the stack and instability of the front-end amplifiers. A permanent solution was needed to improve the data quality with new age technology. One way is to design and mount amplifier cum discriminator boards as close as possible to the detector and transmit the differential logic signals to the digital front-end. Upgradation was also needed to improve the power consumptions of the electronics. A compact 8-in-1 NINO amplifier-cum-discriminator boards and Adaptor boards have been specially designed and developed. A scheme of modified DAQ system, integration and RPC performance in terms of efficiency and noise rate are discussed in this proceeding.
