“…The resulting environment has necessitated the development of new electronics, both on-and off-detector, to ensure the continued peak performance of the Tilecal. The development, production, installation and commissioning of the new electronics falls under the Tilecal Phase-II upgrade [5][6][7]. The Tilecal Low-Voltage Power Supplies (LVPS) and the components therein will be upgraded as part of Phase-II upgrade.…”

The upgrade of the ATLAS hadronic tile-calorimeter (TileCal) Low-Voltage Power Supply (LVPS) falls under the high-luminosity LHC upgrade project. This article serves to provide an overview of the development of a burn-in test station for a Phase-II upgrade LVPS component known as a Brick. These Bricks are radiation hard transformer-coupled buck converters that function to step-down bulk 200 V DC power to the 10 V DC power required by the on-detector electronics. To ensure the high reliability of the Bricks, once installed within the TileCal, a burn-in test station has been designed and built. The Burn-in procedure subjects the Bricks to sub-optimal operating conditions that function to accelerate their aging as well as to stimulate failure mechanisms. This results in elements of the Brick that would fail prematurely within the TileCal failing within the burn-in station or to experience performance degradation that can be detected by followup testing effectively screening out the ’weak’ sub-population. The burn-in station is of a fully custom design in both its hardware and software. The development of the test station will be explored and the preliminary burn-in procedure to be employed will be presented. The commissioning of the burn-in station will be presented along with a summary and outlook of the project.
