FATALIC: a fully integrated electronics readout for the ATLAS tile calorimeter at the HL-LHC

The ATLAS Collaboration has started a vast program of upgrades in the context of high-luminosity LHC (HL-LHC) foreseen in 2024. The current readout electronics of every sub-detector, including the Tile Calorimeter (TileCal), must be upgraded to comply with the extreme HL-LHC operating conditions. Th...

Sumario:The ATLAS Collaboration has started a vast program of upgrades in the context of high-luminosity LHC (HL-LHC) foreseen in 2024. The current readout electronics of every sub-detector, including the Tile Calorimeter (TileCal), must be upgraded to comply with the extreme HL-LHC operating conditions. The ASIC described in this document, named Front-end ATlAs tiLe Integrated Circuit (FATALIC), has been developed to fulfill these requirements. FATALIC is based on a $130\,$nm CMOS technology and performs the complete processing of the signal, including amplification, shaping and digitization on a large dynamic range A dedicated channel for low current is also designed in order to perform absolute calibration with radioactive cesium source, producing a known but low signal with a typical frequency of $100\,$Hz. In this document, the design of FATALIC is described and the measured performances as well as results of tests using beam of particles at CERN are discussed.
