Description
The Phase-II upgrade of the ATLAS Tile Calorimeter (TileCal) for the High-Luminosity Large Hadron Collider will also comprise the new finger Low Voltage Power Supply (fLVPS) boards to satisfy the new requirements on radiation tolerance, reliability and performance of the device. University of Witwatersrand in South Africa share the production of 2048 fLVPS boards with UTA in America. University of Witwatersrand produced 1032 of these fLVPS boards. The fLVPS board is upgraded to supply stable and low-noise power and improved redundancy and fault tolerance for high energy performance in any harsh environment. Sourcing, assembling, and verification of components is done using a methodical way which complies with ATLAS standards. All quality assurance is managed in three steps: initial testing, burn-in and final testing. The production pipeline, testing protocols and performance metrics for the fLVPS boards are presented in this work. The outcomes shows that these systems meet all aspects of the necessary parameters regarding voltage stability, temperature stability, power efficiency, noise level and reliability. The work also demonstrates the contribution of Wits to providing hardware to conduct a large international experiment and the experience they gained from building in electronics production and testing.
