CMS HCAL VTRx-induced communication loss and mitigation / Cummings, Grace (speaker) (University of Virginia)
The Compact Muon Solenoid (CMS) Phase 1 Hadron Calorimeter Upgrade (HCAL) saw the first large-scale use of VTRx modules, optical transceivers designed to be radiation and magnetic field tolerant. During Run II of the Large Hadron Collider, the CMS HCAL experienced a short period of communication loss that revealed a manufacturing weakness in the VTRx affecting nearly half of the communication links.

High-accuracy 4D particle trackers with Resistive Silicon Detectors (AC-LGADs) / Arcidiacono, Roberta (speaker) (Universita e INFN Torino (IT))
Future particle trackers will have to measure concurrently position and time with unprecedented resolutions, approximately 5 microns and 10 ps respectively. A promising good candidate are the AC-LGADs, silicon sensors of novel design, with internal gain and an AC-coupled resistive read-out to achieve signal sharing among pads. [...]

Towards Optical Data Transmission for High Energy Physics Using Silicon Photonics / Prousalidi, Theoni (speaker) (National Technical Univ. of Athens (GR))
Future upgrades of CERN Experiments will require low power optical data links to support ever-increasing data-rates at ever-higher radiation levels. Silicon Photonics is a CMOS optoelectronics technology compatible with such requirements. [...]

48V input rad-hard DCDC converters for HEP experiments: development and results / Antoszczuk, Pablo Daniel (speaker) (CERN)
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. [...]

Serial powering and signal integrity characterisation for the TEPX detector for the Phase-2 CMS Inner Tracker / Reimers, Arne Christoph (speaker) (Universitaet Zuerich (CH))
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. [...]

rPOL2V5: a compact radiation-hard resonant switched-capacitor DC-DC converter for the CMS HGCAL / Caregari, Stefano (speaker) (National Central University (TW))
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. [...]

The Scalable Readout System as a common initiative - a personal review / Lupberger, Michael (speaker) (University of Bonn (DE))
When the RD51 collaboration formed in 2008, the community initiated efforts for a standardised common readout system, the Scalable Readout System (SRS). The APV25 chip, originally designed for the CMS silicon strip detector, was the working horse within the first decade reading out gaseous detectors. [...]

Installation, integration and first operating experiences of the ALICE ITS Upgraded Readout System / Groettvik, Ola Slettevoll (speaker) (CERN)
The ALICE Inner Tracking System has gone through a significant upgrade for the upcoming third running period of the CERN LHC. The new detector consists of seven layers of high-granularity pixel sensors, while 192 custom FPGA-based readout units control the sensors and transmit the data upstream for analysis. [...]
