Power, Grounding and Shielding

Oral

The entire CMS silicon pixel detector will be replaced to operate at High Luminosity LHC. The novel scheme of serial powering will be deployed to power the pixel modules and new technologies will be used for a high bandwidth readout system. In this contribution the new TEPX detector will be presented, with particular focus on a novel concept to provide both power and data connectivity to the...

Oral

A high power density resonant switched capacitor DC-DC converter (rPOL2V5) has been developed as a possible alternative to the bPOL2V5, of particular interest to the CMS High-Granularity Calorimeter (HGCAL) due to the relatively compact 12nH air-core inductor that it requires. The converter is based on an ASIC developed in a 130nm CMOS technology. It is powered by a 2.5V input, it can supply a...

Two new radiation-hard DCDC converters are in development, which tolerate a higher input voltage (up to 48V) and provide a larger output power compared to existing solutions. They are called bPOL48V and rPOL48V, and they employ Gallium Nitride devices. bPOL48V can provide 12A of output current with 90% efficiency and is close to production readiness, while rPOL48V is in an early stage of...
