The Burn-in testing of advanced custom low-voltage power supply components within ATLAS TileCAL testing facilities.

The upgrade of the ATLAS hadronic tile-calorimeter (TilCAL) Low-Voltage Power Supply (LVPS) falls under the high-luminosity LHC upgrade. This upgrade is composed of multiple projects that when combined will form the latest iteration of the LVPS. One such project is focused on an LVPS component known as a brick, which is a transformer coupled buck converter. These bricks function to step-down bulk 200VDC current to the 10VDC current required by the front-end electronics of a TileCAL module.Due to the LVPS bricks being located on-detector they are of a highly refined custom design. Within the development and production phase of these bricks the use of a custom built test-bed known as the Burn-in station is required. The Burn-in test station functions to detect the premature failure of electronic components on an LVPS brick via a process known as accelerated aging. By doing so the test station is able to ensure improved reliability of an LVPS brick once installed within ATLAS and therefore occupies a key role within the TileCAL LVPS brick testing facilities.
