Accelerator Sequencing and Synchronisation (Timing)
Accelerator Sequencing and Synchronisation (Timing) What is the CERN Controls Timing System ? The Timing system ensures that CERN’s accelerator complex behaves as expected as a function of time. It calculates and broadcasts events based on GPS clocks, Operator input, database configurations and accelerator interlocks. It is a distributed system in constant change, resulting from

Software Infrastructure for Low-level Equipment ControllerS (SILECS)
Software Infrastructure for Low-level Equipment ControllerS (SILECS) What is SILECS? Programmable Logic Controllers (PLCs) and other micro-controller families are essential components of the CERN control system. Both have their weaknesses and their strengths and as they typically present custom communication protocols, it is difficult to federate them into the control system using a single communication

Open Analogue Signal Information System (OASIS)
Open Analogue Signal Information System (OASIS) What is OASIS? OASIS stands for Open Analogue Signal Information System. Its purpose is to acquire analogue signals from devices in the particle accelerators in CERN and display them in a convenient, graphical way. It is used by equipment specialists, engineers and operators in order to watch the behavior

Controls Middleware (CMW)
Controls Middleware (CMW) What is CMW? The CMW (Controls Middleware) service provides a communication infrastructure for all CERN accelerators, enabling client applications to connect, control and acquire data from all types of equipment. This is achieved via a common naming protocol called Device-Property Model and a set of common operations a client application can execute

Controls for the SPS experimental areas (CESAR)
Controls for the SPS experimental areas (CESAR) What is CESAR? CESAR is a client-server control system for the beamlines of the SPS experimental areas, used by an overall community of over 1000 experimental physicists. Apart from controlling 30 different types of hardware, CESAR is capable of reliably managing beamline settings. How is CESAR made? Technically,

Front-End Software Architecture (FESA)
Front-End Software Architecture (FESA) FESA wiki (CERN only) What is FESA? FESA is a comprehensive environment for equipment specialists to design, develop, test and deploy real-time control software written in C++ for front-end computers (in the context of CERN’s control system, Front-End refers to computers which control particle accelerator’s equipment, and has nothing to do
