Purpose, scope and roles of ITERMAG, the ITER Magnetics Diagnostic Consortium
This is a document for ITERMAG discussion, prior to establishing the formal documents inside the Consortium Agreement, which will be:
- The ITERMAG Consortium Agreement
- Annex I Scope and roles of the ITERMAG consortium
- Annex II Cost sharing and revenu sharing for the ITERMAG Consortium
Preamble
Work on the ITER magnetics diagnostics is currently being carried out under EFDA Tasks by 4 Associations, namely CEA, CIEMAT, CRPP and ENEA. CRPP presently assumes the project leadership. This cluster of Associations is referred to as the ITERMAG Cluster. A great deal of R&D work was previously performed by ITER IO over the last 10 years.
Procurement of this set of diagnostics will be under Fusion for Energy (F4E) and to guarantee the transition from R&D and preliminary design support at the EFDA level to detailed design, procurement, commissioning and operation, the creation of a Consortium is proposed by the same Associates, referred to as the ITERMAG Consortium.
At the time of writing (March 2008) a number of issues are being handled:
- Purpose of the ITERMAG Consortium
- Technical scope of the ITERMAG Consortium
- Roles of the ITERMAG Consortium
- Structure of the ITERMAG Consortium
- Legal and financial identity of the ITERMAG Consortium
This present document is restricted to the first three issues, namely the purpose, scope and roles of the Consortium.
Purpose of the ITERMAG Consortium
The purpose of the ITERMAG Consortium is driven by the currently perceived requirements of F4E, of ITER IO and of the present ITERMAG Cluster members. The principle drivers for this scope are to:
- Offer a single competent technical interface on the ITER Magnetics Diagnostic for F4E
- Offer a single competent scientific interface to the ITER Magnetics Diagnostics for ITER IO
- Offer a single competent scientific interface to the ITER Magnetics Diagnostics for the scientific community
- Offer a single competent unit for defining the scientific and technical completeness and consistency of the design of this diagnostic set
- Offer a single competent unit to oversee the detailed design contracts with industry
- Offer a single competent unit to oversee the manufacturing and installation contracts with industry
- Offer a single unit for the efficient scientific and technical deployment of this diagnostic set, from installation through commissioning into operation
- Offer a single unit to guarantee optimal scientific exploitation of this diagnostic set, generating all interfaces to other ITER IO activities
The Consortium Agreement is created with the intention to last for the duration of the construction and operation of ITER, although the Consortium can modify this duration.
Technical scope of the ITERMAG Consortium
The ITERMAG Consortium Agreement specifies that the Members will respond in a coordinated and agreed fashion to calls for interest and calls for tender within the technical scope of the consortium. This section defines “within the technical scope” and clarifies the usage of the terms within this definition.
The technical scope of the ITERMAG Consortium is defined to include: “ aspects of the development, design, modeling, testing, construction, installation, commissioning, maintenance and scientific use of sensors and associated equipment used for the measurement of magnetic fields in ITER”
Development refers to any process which leads to a revised concept or implementation of any appropriate measurement method. It includes “research”.
Design refers to any process which leads to the establishment of a specific implementation of any measurement method.
Modelling refers to any process which leads to an analytical, or computerized or quantified description of the behaviour of measurement methods. It includes, but is not restricted to the passive 3D conducting structures and active 3D conducting structures surrounding the plasma and the plasma itself.
Testing refers to any process which leads to the qualification of any measurement method, during development, prototyping, factory or site testing, commissioning and maintenance.
Construction refers to any process which leads to a physical realization of a sensor or associated equipment for any measurement method.
Installation refers to any process by which constructed equipment is installed in a different environment, whether at a factory site, or on site.
Commissioning refers to any process which leads to the deployment of a sensor or associated equipment for any measurement method. It includes, but is not restricted to installation and testing.
Maintenance refers to any process which periodically or occasionally leads to improvements to, repair of and re-qualification of a sensor or associated equipment for any measurement method.
Scientific use refers to any process which makes use of the data derived from the sensors or associated equipment of any measurement method, for a scientific purpose. This usage may take place during operation, or after operation. This usage includes, but is not restricted to the following illustrative activities:
- Reconstruction of the plasma equilibrium and its time evolution, possibly including non-magnetic diagnostic information
- Development of estimators of feedback variables for n=0 and n>0 control
- Identification of MHD activity at timescales faster than equilibrium control
- Interpretation of data produced by the sensors and associated equipment
- All application software to provide for the above usage of the data
- All application software to treat the measurement data at source
Sensor refers to any component which is designed to be sensitive to a magnetic field.
Associated equipment refers to any component which is designed to transport or modify signals derived from sensors. It includes, but is not restricted to the full electronics chain up to delivery to a global data handling system.
Magnetic fields includes all those magnetic fields which are due to the process of confining hot plasma. It includes the confining fields, the equilibrium fields, the fields produced by the plasma and all fields due to induced currents in passive conducting structures. It includes fields modified by the presence of magnetic materials.
Roles of the ITERMAG Consortium
The various roles of the ITERMAG Consortium clearly have to be defined for 4 separate timelines:
- R&D and design to complete the engineering design of the diagnostic
- Detailed design and manufacturing by industry
- Installation and commissioning up to first plasma
- Maintenance and scientific exploitation of the diagnostic
The work for linked to the ITER magnetics is broken into the following phases:
- Design
- R&D
- Creation of Proc. Arrangement
- Creation of Work Programme
- Creation of consortium
- Call for interest to consortium
- Call for interest to industry
- Selection of industrial partners
- Industrial contracts
- Manufacturing and testing
- Development of software
- Installation and testing of hardware
- Installation and testing of software
- Commissioning of diagnostic
- Integration into CODAC
- Benchmarking of EM models
- Continuous operation and maintenance
- Scientific exploitation
During these phases, different roles are played on the different interactions. These interactions have been drawn for all phases, to analyse the problem.
Figure 1 shows the potential interactions between the actors in all these phases.

As a result of these considerations, 3 principle roles are considered for the ITERMAG Consortium, and are considered in what follows:
- Contractor
- Consultant engineers
- Manufacturer
Contractor
In the role of contractor, the Consortium accepts a contract to supply a product to the client. This product can be R&D, planning, design, software, integration, development of layout. It includes all activities linked to the production of functioning systems, with the exception of “mass production” which we refer to as “manufacturing”.
Figure 2 illustrates this direct link.
Figure 2. Role as contractor to F4E
Consultant engineer
Terminology varies here. The intended sense is “Assistance au maître de l’ouvrage” which is an appropriate relationship much used in France.
Under this relationship, the added value of the Consortium is to support its client (F4E) on all technical issues related to a contract which is placed with industry. This assistance includes the selection of an appropriate industry, calls for interest and tender, preparation of contracts, overseeing of the planning and manufacturing process, of quality control, of all factory and site testing of any delivered product.
In view of the difficulty of placing a manufacturing contract through the Consortium, this role is the one which appears to be most appropriate to the procurement phase.
We assume (and first contacts support this assumption) that the Member institutions will consider all consultant engineering activities as within their mandate.
Figure 3 illustrates the consultant engineering role.

Manufacturer
At the time of writing (Spring 2008), the third role, namely “Manufacturer” appears to be excluded for the original members which are EURATOM Associates. The principle reason is that these institutions are publicly funded for the purposes of scientific research and development, not for competing with manufacturing industry. The term manufacturing includes the generation of multiple manufacturing drawings from existing detailed design drawings.
Two areas of uncertainty arise here. Firstly, small batches, or pre-series, might be considered as dominated by R&D costs, and therefore not “competing with industry”. Secondly, the Consortium might find it useful to expand to include one institution which does not have this restriction. This potential role is therefore not excluded from the Consortium Agreement, although it cannot be used today.
Figure 4 illustrates the manufacturing role, contracting directly to industry.
