　　报告内容简介  

　　

　　This presentation will cover the latest development in the upgraded design of Atlas Tile Calorimeter Front-end readout electronics and data acquisition system for ATLAS experiment at High Luminosity LHC.

　　The Tile Calorimeter is essential for measuring the energy and direction of the quarks and gluons produced in the collisions. These appear in the detector as jets of charged and neutral particles. The calorimeter consists of a fine-grained steel matrix with 430,000 “tiles” of plastic scintillator dispersed in the matrix. Optical fibers from the tiles are grouped into 5,000 calorimeter cells, whose signals are detected and recorded by 10,000 photomultiplier tubes and associated readout electronics. Signals from each photomultiplier are digitized every 25ns and processed with dedicated electronics to obtain energy and time measurements.
