The control systems of the four LHC experiments are being developed in common within the Joint COntrols Project (JCOP).

LHCb's Experiment Control System is in charge of the configuration, control and monitoring of all the components of the online system. This includes all devices in the areas of: data acquisition, detector control (ex slow controls), trigger, timing and the interaction with the outside world.

Framework

The central ECS team will provide a framework to the sub-detectors groups which will need to configure and develop the specific control functions for their sub-detector. 

The control framework is based on a SCADA (Supervisory Control and Data Acquisition) system called PVSSII and it will have to be interfaced to all experimental equipment.

Recommended Components and Interfaces

• Interface to Electronics

• Detector Control Devices (HV, LV, temperatures, etc.)

Program of work & activities

• Develop the electronics interfaces to ECS (SPECS, CC-PCs)

• Framework development (sub-system integration, partitioning, etc.)

• LHCb Framework (=JCOP Framework + LHCb specific components)

• Framework deployment in the Test Beam

• Test Beam support

• Provide consultancy and support to sub-detectors

• Continue gathering sub-detector requirements

  • Scale of the System (or what we think we know already)

• Configuration database

• Gaucho (Gaudi Component Helping Online)
