A new test-bench design and performance testing of a Low Voltage Power Supply for the ATLAS Tile Calorimeter front-end electronics

We present test-station designs for testing the latest version of a switch-mode power supply for the front-end electronics of the ATLAS hadron TileCal(Tile Calorimeter)at the LHC. We further discuss the steps taken to test the new TileLVPS (Low Voltage Power Supply), using a custom based software to perform tests and graphically display and record all performance metrics. The test station verifies performanceand electrical specificationslaid out by ATLAS TileCal and ensures protection against over-temperature, over voltage and over-current. These test stations will build upon the previous generation of testing stations used in the initial production of the TileCal system and will power the next generation of upgraded LVPS hardware.
