The LHC Logging service is aimed to satisfy the requirement of capturing and storing any relevant accelerator data to track its variation over time. This service is presently operational on the whole CERN accelerator complex, from ion and proton sources to LHC, and has become a critical component of the CERN control systems. The focus is given to the measurement part of this service, which is responsible for the data acquisition and preparation (processing, filtering, concentration) prior to its storage in database and file systems. Incoming data is often processed by a concentration layer, the processes that transform data of multiple devices into single values according to well defined rules and then publish them further on, to the LHC Logging among others. The paper describes the architecture and presents the solutions to the very challenging requirements imposed by the LHC in terms of overall performance and reliability. The efficiency of the data acquisition and filtering as well as the flexible software design are highlighted.

After a detailed study of the PS complex requirements by experts of the CERN controls & operation groups, a proposal to develop a new system, called Injectors Control Architecture (InCA), was presented to and accepted by the management late 2007. Aiming at the homogenisation of the controls systems across CERN accelerators, InCA is based on components developed for the Large Hadron Collider (LHC) but also new components required to fulfill operation needs. In 2008, the project was in its elaboration phase and we successfully validated its architecture and critical use-cases during several machine development sessions. After a minute description of the architecture put in place and the components used, this paper will describe the planning approach taken combining iterative development phases with deployment in operation for validation sessions.
