    For the ATLAS Inner Tracker Pixel Outer Barrel, robust grounding and shielding (G&S) are critical to ensure the required detector performance. This contribution presents the G&S strategy developed to avoid ground loops, enhance common-mode noise rejection, and maintain shielding integrity for the pixel modules. Results from electromagnetic compatibility (EMC) testing of the first...

    The Low Voltage Power Supply is a modular power converter stepping down 380VDC to 12VDC to power the widely used bPOL12V point-of-load converters. It is designed to operate in the radiation and magnetic-field environment of the CMS towers of experimental cavern. Three prototype iterations underwent radiation and magnetic-field testing, followed by progressive technical qualification. We...

    The low-voltage supply chain for the High Granularity Calorimeter (HGCAL) Phase-2 upgrade of CMS powers the front-end electronics of 620m2 of silicon sensors and 370m2 of SiPM-on-Scintillating tiles. This chain consists of Low-Voltage Power Supplies custom-developed by CMS to operate in the experimental cavern, that power bPOL12V-based DCDC converters located inside the experiment, and custom...
