“…Traditionally, this has been done with custom electromechanical relay-based cards controlled serially via CAMAC crates. In order to improve the robustness and maintainability of the system, while keeping it analog to preserve the low latency, a VME card based on Analog Devices' AD8116 analog matrix chip has been developed. …”

“…Various upgrades were performed on the Large Hadron Collider (LHC) Beam Dumping System (LBDS) during Long Shutdown 1 (LS1) at CERN, in particular to the Trigger Synchronisation and Distribution System (TSDS): A redundant direct connection from the LHC Beam Interlock System to the re-trigger lines of the LBDS was implemented, a fully redundant powering architecture was set up, and new Trigger Synchronisation Unit cards were deployed over two separate crates instead of one. These hardware changes implied the adaptation of the State Control and Surveillance System and an improvement of the monitoring and diagnosis systems, like the various Internal Post Operation Check (IPOC) systems that ensure that, after every beam dump event, the LBDS worked as expected and is 'as good as new' for the next LHC beam. …”

“…In DAQ/EF-1 there is an element called the LDAQ which is responsible for providing local run-control, error-handling and reporting for a number of read- out modules in front end crates. This element is also responsible for providing event data for monitoring and for the interface with the global control and monitoring system (Back-End). …”
