JCOP Overview JCOP External Review 10th-12th March 2003
Overview of presentation • Project Start-up • Structure and Reporting • Complications • Project Scope • Project Approach • Overview of Activities • Potential Issues • Summary • From my point of view
Project Start-up • JCOP was established in January ’98 with David Myers (IT-CO) as Project Leader • Reasons: • Recommendation by inter-divisional / inter-experiment WG • Similar technical requirements • More efficient use of shrinking resources • Collaboration between five equal partners - the four LHC experiments and IT-CO (later also EP-ESS) • Mandate: “To develop a common Framework and components for detector control of the LHC experiments and to define the required long-term support.“ • Mandate and reporting structures updated in February 2000 • David Myers replaced by Wayne Salter as Project Leader in January 2001
JCOP Steering Group (SG) • Responsible for addressing strategic and resource issues and for overseeing the progress of the project • Meetings held 3-4 times per year • Report by Project Leader on the status of activities • Other issues of concern at the time • Membership: • Experiment Technical, DAQ and Controls Co-ordinators • Representatives of the IT and EP management (DL or DDL) – one acting as Chairman • Group Leaders of support groups (IT-CO/EP-ESS) • Project Leader (secretary) • Experiment GLIMOSs (DSS)
JCOP Executive Board (EB) • Responsible for the overseeing the day-to-day running of the project • Establishing the Programme Plan, which defines activities, milestones, resource requirements • Approving sub-projects • Defining priorities • Meets bi-weekly • Reports from relevant meetings • Issues of concern at the time • Membership: • Project Leader (Chairman & Secretary) • Experiment Controls Co-ordinators • Group Leaders of support groups (IT-CO/EP-ESS) • Other people invited by the Chairman if appropriate • Steering Group Chairman (ex-officio)
JCOP Project Team • Forum for technical discussions and presentations • Forum for the dissemination of information and the exchange of information and ideas between the experiments • Bi-weekly with published minutes • Participation: • All people involved in controls in the LHC experiments • Members of the support groups • Attendance: • Typically 30-40 people at each meeting • People from other controls domains at CERN

Complications Some complications are inherent with common projects • Different approaches to controls in the experiments Þ initial difficulties in defining the scope and responsibilities (initial Programme Plan) • Initial difficulties in obtaining requirements and milestones • Unclear reporting lines • As well as the change of PL there have been several changes of experiment controls co-ordinators – LHCb (1), ALICE (2), CMS (2) Situation improved with the revised mandate and reporting – particularly the separation of functions

JCOP Approach • Decisions made via consensus • Compromise • Involve the experiments as much as possible in the JCOP sub-projects • Commercial solutions wherever possible and beneficial • Limited manpower • Maintenance issues • General purpose and maintainable solutions and components • Global rather than local optimisation • Sufficient to meet need • Sufficient flexibility • Experiments choose which to use and for what

Programme Plan - I • Technology Survey (completed) • Axel Daneels and 10 staff from IT-CO and one coopérant from ALICE • 1997-2000 • Development of Supervisory Framework (on-going) • Manuel Gonzalez Berges with 3FTEs from IT-CO • Specific developments done by the experiments • Communications with CERN infrastructure services (on-going) • Participation of Wayne Salter and Mark Beharrell (IT-CO) and Clara Gaspar (LHCb) in the LDIWG to define data exchange mechanism (DIP) • Applications to Interface to CERN Infrastructure (not started) • Dependent on the outcome of the above • Control of Gas Systems (on-going) • Renaud Barillère (IT-CO)/Stefan Haider (EP-TA1) and 2.4 FTEs from IT-CO, 0.5 FTE EP-TA1 and 0.8 FTE from EP-ESS on loan • Gamma Irradiation Facility (on-going) • Mike Clayton of EP-ESS with some fraction of a technical student • Front-End Communications (not started) • For commercial equipment OPC being used as a standard • DIM selected as an intermediate solution for custom equipment • No common requirements for other mechanisms
Programme Plan - II • Detector Safety System • Bruce Flockhart with 2 FTEs from IT-CO • Prototype being developed • Rack Control (on going) • Paul Maley from EP-ESS as part of the common rack project • Crate Control (on going) • Handled as part of the common rack tendering of EP-ESS • Sub-detector Cooling and Ventilation (not started officially) • A number of discussions held to clarify responsibilities • Control of High and Low Voltage (not started officially) • Support provided to CAEN, WIENER and ISEG for the development of OPC servers • Temporary solutions developed by IT-CO while awaiting the above • Vertical Slice (completed) • Sergei Zelepoukine as a Project Associate in IT-CO with support from IT-CO • February - July 2001
Additional Activities • Database Issues • Componentware • Prototypes • ATLAS TRT GCS • CMS B1 GCS • ALICE HMPID • CMS B2 GCS • NA60 GCS • Show Cases and Hands-on Environments • Several equipment labs in IT-CO • SCADA, DSS, OPC, PLCs, Field bus equipment • Tutorials and demos • Test machines and H/W
Use of JCOP Technologies • Used in Fixed Target Experiments • HARP • NA60 • COMPASS • Enable technology to be used in realistic environment • Provides good feedback to development team • Low-level of support required • Showed value of experiment contact persons • Being introduced for LHC experiments
JCOP Workshops • Opportunity to exchange information in a wider audience, both within and between experiments • JCOP I • Understand best practice from ‘current’ experiment • Identify the critical technical issues • JCOP II • Get an update on the experiment controls activities • Discuss technology choices and particularly SCADA • Discuss the future direction • JCOP III • Get an update on the experiment controls activities • Present/demonstrate the available JCOP components and tools • Discuss the future direction and priorities
Concerns • Adoption of components by sub-detectors • Small attendance at JCOP III • Major test-beam activities this year • ELMB Support • Developed for/by ATLAS but is being widely used not only in ATLAS • No official S/W support for non-standard SW • Final production planned this year • Long-term maintenance • Availability of resources
Summary • Wide range of activities have been undertaken • Many common components already provided • We will hear more about these during this review and see some of them in demos • Further components are under development • Will be described in other presentations • Provides building blocks for the experiments to construct their control systems • Need to ensure that the sub-detectors gain experience with these components • Long-term maintenance to be addressed
