Abstract
The LHCb detector upgrade [1] foresees a new trigger-less readout system operating at 40 MHz. A new muon readout system, based on the nSYNC radiation tolerant ASIC [2] , [3] developed in the UMC 130 nm technology, will be installed and commissioned in 2019-20. The nSYNC chip implements all the required functionalities required: data alignment, time measurement of arriving signals from the front-end electronics using fully digital TDCs, data zero suppression. At the nominal luminosity, and during the ten years of upgrade operation, the chip will be exposed to a total dose of 130 Gy and fluence of 2 • 10 12 cm -2 1MeV neutrons equivalent, in the regions with the highest radiation levels. To guarantee a proper operation in these conditions the most sensitive functional blocks of the chip have been equipped with a triple modular redundancy system (TMR) and with error detection and correction system (EDAC) based on the Hamming code.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
