Summary: | Abstract
The ATLAS detector is set to undergo a substantial upgrade
termed the “Phase-II” upgrade during the Long-Shutdown in
preparation for the start of operation of the High Luminosity Large
Hadron Collider (HL-LHC). This paper describes the development and
implementation of the Phase-II upgrade low voltage power supply
transformer-coupled buck converter (Brick) test bench. A large
scale production of approximately 2048 finger low voltage power
supplies, with an identical output voltage, is set to be undertaken
in the year 2022. This production will culminate in the complete
replacement of the LVPS Brick V7.5.0 currently installed within the
Tile Calorimeter. Due to the location of the Bricks within the inner
barrel of the TileCal their reliability is of the utmost
importance. Therefore, the implementation of performance screening
will be implemented and will involve the testing and certification
of all Bricks produced. A custom test bench has been developed in
order to facilitate the above-mentioned testing. The test bench
described herein quantifies and logs the performance of an upgrade
Brick allowing for comparison with predefined performance metrics
before being approved and subsequently installed on-detector. |
