Description
To handle the intense radiation at the High-Luminosity LHC, the ATLAS Liquid Argon Calorimeter readout electronics are being upgraded. The includes the production of custom ASICs, including the COLUTA chip—an 8-channel, 15-bit, 40 MSPS ADC.
The ADC meets and exceeds the specifications for the analog performance and the HL-LHC radiation tolerance. With 80,000 chips needed, robotic test stands are performing quality control, with performance metrics stored locally and in a centralized database. Updates on chip performance, radiation testing, robotic systems, and production yields will be presented.
