Cover Story: The firmware developed for the readout and trigger processing of the information that emerged from the BIS78-RPC Muon Spectrometer chambers in the ATLAS experiment at CERN is presented here, together with data processing techniques, data acquisition software, and tests of the readout chain system, which represent efforts to make these chambers operational in the ATLAS experiment. This work is performed in the context of the BIS78-RPC project, a pilot deployment of a new generation of sMDT+RPCs in the experiment, which will be installed in the Phase II upgrade. On-chamber front-ends include an amplifier, a discriminator ASIC, and an LVDS transmitter. The signal is digitized and then processed by a Xilinx FPGA, which is the heart of the readout and trigger processing, using various techniques. View this paper
