About JCOP

The Joint COntrols Project (JCOP) is a collaboration between the LHC experiments, the PH Department and EN-ICE, the Controls Group in the Engineering Department. It was started in order to encourage the use of controls solutions developed in common by the LHC experiments and its partners in the PH and the IT Departments. The document setting out the project proposal may be found here. Given the increasing constraints on manpower, as well as the evident similarity in technical requirements for controls amongst the experiments, the project should enable more efficient use of resources to be made. The background, objectives, and other details of the project may be found in the Initial Project Plan and a report on the first phase of the project is available at the report in the document Initial Phase. A major External Review of the Joint COntrols Project project was held at CERN in March 2003. In 2009, and following the reorganization of the controls support group at CERN, an internal review of the project took place which led to a clarification of reporting lines and a revised mandate. 

Day-to-day decisions are taken taken by the JCOP Coordination Board which is chaired by the JCOP Project Leader. The Coordination Board meets bi-weekly and includes the experiments' Controls Co-ordinators and representatives from EN-ICE and PH-DT. The JCOP Project Leader reports to a the Extended Co-ordination Board, previously known as the Steering Group, which also include representatives from the EN and PH management. The Extended Coordination Board meets quarterly and must approve the programme of work, as well as identify and make available the necessary resources.

Today, JCOP provides, supports and maintains a common Framework of tools and a set of components. These allow the configuration, the monitoring and the operation of the different sub-detectors and also include communication mechanisms with the Data Acquisition/Trigger systems as well as with external systems such as the CERN infrastructure services and the LHC.

A number of studies and sub-projects have been completed in the framework of JCOP since its origins. Presently the work in JCOP is divided into four major sub-projects:


Detector Safety System


Tools and Guidelines for implementation.

GAS Control

In collaboration with Gas Working Group

Rack Control

In collaboration with EN/EL

During these years, JCOP has organized three major workshops:

JCOP Workshop-3

CERN on 5-6 June 2002

JCOP Workshop-2

CERN on 6-7-8 September 1999

JCOP Workshop-1

CERN on 3-4-5 June 1998
