SECOND MEETING OF THE ITER PREPARATORY COMMITTEE
By M. Drew, EU Contact Person for ITER Transitional Arrangements
The Committee charged to oversee the ITER Transitional Arrangements (ITA), the ITER Preparatory
Committee, held its second meeting on 24 September 2003 at the JET Facilities at Culham, UK. Dr. Umberto
Finzi of the European Commission was chairman.
This was the first such meeting since the formal accession to the ITER Transitional Arrangements of the threenew participants to the ITER Negotiations – China, the Republic of Korea and the USA (see Newsletter issue
No. 7, August 2003, Note by the Editor) – who thus were officially represented in the meeting for the first time.
The full list of the currently designated members of the Committee and its Contact Persons (CP) is shown
below.

Dr. N.A. DAVIES
Dr. M. ROBERTS (CP)This meeting was also the first since the succession by Dr. Yasuo Shimomura to Dr. Robert Aymar as Interim
Project Leader (IPL). Welcoming Dr. Shimomura in his new capacity, the Committee paid tribute to the outstanding contributions of his predecessor to the definition, design and promotion of ITER, and expressed thegratitude of all Participants to Dr. Aymar and its best wishes for future success in his new appointment.
The technical activities of the ITA were the main focus of the Committee’s discussions. The Committee took
note of the IPL’s Status Report on ITA Technical Activities and endorsed the IPL’s proposals for the top levelstructure of the International Team, including the designation of Dr. Pietro Barabaschi as Deputy to the IPL.

The Committee took note of the IPL’s proposals on Participants’ contributions to the ITA and of theParticipants’ stated intentions and expectations in this regard. Several Delegations pointed out that access tonecessary resources would depend strongly on progress made towards the Agreement. All Participants wereinvited, in the shared interests of the project, to respond constructively to the specific technical areas where
the IPL reported a lack of resources.
Following a presentation from the IT on Project Management Tools, the Committee expressed support, in general, for the proposed strategy designed to provide the current team with the CAD and Data Management elements necessary to prepare for an efficient start of ITER construction, and asked the IT Leader to report onan estimate and time profile of expenditure during the period to mid-2004.
Dr. David Campbell, Chairman of the International Tokamak Physics Activities (ITPA) Co-ordinating
Committee, gave a presentation on ITPA Support for the ITER ITA. The Delegations recognized the central
role of the IPL in assessing the relevance to ITER of proposals under the ITPA. Some Delegations said thatthey would like to have a positive assessment by the IPL of proposed meetings of the ITPA and its TopicalGroups as a precondition of their support within the ITER framework. The IPL was invited to assess future
proposals for ITPA meetings for this purpose.
The Committee supported the proposals to re-establish the ITER Test Blanket Working Group.
The US Delegation outlined its view of the need for a comprehensive review of the project baseline to takeplace under the Nominee Director General so as to provide a reliable basis for the start of physical construction, and for the related requests for funding. In the US view, the ITER Preparatory Committee should have arole in the coming year in overseeing the preparation for such a review; similarly the Committee should havea role in overseeing the development of the Project Risk Management Process and tools, given the criticalimportance of cost control.
The Committee agreed that the phasing of planned future financing should be further discussed among theParticipants with a view to establishing as far as possible a common basis for the start of ITER construction.
Finally the IPL was asked to estimate the project’s needs for cash to support common expenses over the coming two years and to report on this matter to the next meeting, which has been set tentatively to take place inthe margins of N-10.

TENTH NEGOTIATORS’ STANDING SUB-GROUP (NSSG-10) AND RELATEDMEETINGS
by M. Drew, EU Contact Person
The Tenth Meeting of the ITER Negotiators’ Standing Sub-Group (NSSG-10) and related meetings were held
during the period 18–27 September 2003 at Culham, UK, at the kind invitation of UKAEA-Euratom, who

Topical Working Groups in support of ITER NSSG-10

2Participants at the Meeting

placed their JET meeting facilities at the disposal of the Sub-Group and its Topical Working Groups. The
European Union hosted the meeting, which was also attended by delegations from Canada, China, Japan,
the Republic of Korea, the Russian Federation and the USA.
The meetings followed the now usual format of a series of meetings of specialist Working Groups eachfocussing on a specific aspect of the joint implementation of ITER (see box on the previuos page) followed by
the plenary meeting of the NSSG. With many of the members of the ITER Preparatory Committee present,the opportunity was also taken to hold the second meeting of the Committee (see previous article).
Over the course of seven days the Working Groups met, at times in parallel sessions, to make progress intheir respective topic areas. The work of each group was led by a rapporteur, who subsequently presented
the group’s findings and recommendations to the NSSG as a whole for consideration and guidance.
The focussed discussion enabled further good progress to be made in developing the many different elementsthat will be involved in the joint implementation of ITER. In particular the discussions on procurement allocation reached the stage at which it was possible to charge the NSSG Moderator to transmit to the Participants
at a high level an agreed proposed allocation among the Parties of responsibilities to procure and contributein kind the various systems and components for ITER construction. The proposed allocation is well defined
up to the current limits of understanding on cost sharing and includes areas of flexibility to allow a full matching to the definitive cost sharing as and when it is finally agreed.
The results of the meeting are to be presented to the next meeting of the Negotiators scheduled for midNovember in China.

FIFTH MEETING OF THE ITPA TOPICAL GROUP ON DIAGNOSTICS
by Drs. A.J.H. Donné, FOM Institute for Plasma Physics Rijnhuizen,
and A.E. Costley, ITER International TeamThe Fifth Meeting of the International Tokamak Physics Activities (ITPA) Topical Group (TG) on Diagnostics
was held at the Ioffe Educational Center in St. Petersburg, Russian Federation from 16 to 18 July 2003. The
meeting followed the 30th EPS Conference and was combined with a joint meeting of all ITPA TGs dedicatedto plasma control which was held on 14 July, and with a progress meeting on diagnostic developments ongoing in the Russian Federation which are relevant to ITER and more generally to burning plasma experimental (BPX) devices. About 40 participants attended the ITPA Diagnostics and/or progress meetings and all four
ITPA partners were well represented. For the first time an observer from China attended the Diagnostics TGmeeting.
The key topics reviewed and discussed at the TG meeting were:
●
●
●
●
●
●

detailed measurement requirements for ITER along with their justifications;overall status of diagnostic development for ITER;
progress in the research on the designated high priority topics;
progress with some key BPX/ITER relevant diagnostic developments in progress in the ITPA participantlaboratories;
progress and plans for the work of the specialist working groups;
status and plans for the International Diagnostic Database.

Good progress has been made in the tasks designated as high priority:
1. New concepts were presented for the vertical viewing neutron camera. This device is required to enable
an independent measurement to be made of the alpha particle birth profile. Conventionally thismeasurement is made with a radial and a vertical view neutron camera, but on ITER the coverage of theradial camera has been limited and severe interface difficulties have been experienced in theimplementation of a camera viewing from above the machine. The proposal to extend the radial neutron
camera utilizes additional compact in-plug collimators and detectors that mainly sample the upper andlower regions of the plasma. Together with the existing radial views, about 90% of the plasma is now
covered. The new concepts for the vertical viewing camera are a reduced scale camera viewing fromabove, and a compact camera viewing from within a divertor port. The preliminary work on these concepts
was reviewed.
2. Much progress has been made in the possible impact of the radiation induced electromotive force (RIEMF)
on the performance of magnetic coils made from mineral insulated cables. Recent reactor tests in theJapanese Material Test Reactor (JMTR) have indicated that thermoelectric effects, enhanced by radiation(RMTV), are comparable to or even dominate the net RIEMF contribution to the coil voltage. In principle,
the contribution of RMTV can be reduced by changing coil construction to improve cooling. A temperature
difference over the coil of ~1 – 2 K (as opposed to the present 100 K) may be low enough that the residual
RMTV is negligible, at least for some materials. Such a temperature difference may be achievable for ITER
by using, for example, a copper matrix. This is in any case necessary to guard against a variety ofthermomagnetic effects, which have been calculated to be of similar magnitude. Changing the cable
composition and geometry to be more stable against high energy neutron damage and/or to have lower
transmutation effects can also reduce the impact of RMTV.
3. An initial investigation has shown that many of the measurement requirements for operating in Advanced
Tokamak (AT) mode are already reasonably well covered in the present ITER measurement specifications.
The most critical items are the measurement of the different components of ?, the gradients in a numberof parameters as well as the possibility to match the flexibility in shape control, especially at the top of theplasma. Work on the measurement requirements and justifications for ITER are in progress.
4. New data were presented on the effects of erosion and deposition on first mirrors. The list of suitablematerials for first mirror fabrication is becoming longer. Experimental investigations of the behaviour of firstmirrors in several fusion devices have started and more are being prepared. The analysis of thecomposition of contaminating carbon-based deposit on stainless steel mirror samples exposed during a
recent experimental campaign inside the T-10 vacuum vessel has been completed. Some interesting and4

relevant tests have recently been carried out on NSTX, where a quartz balance has been exposed to theplasma and the net layer deposited per shot determined. In most cases material was deposited typicallyat the rate of 0.2 nm per second of exposure to the plasma but in disruptive shots it was observed thatdeposited material was removed at the enhanced rate of 22 nm/s.
5. In the field of alpha particle diagnostics, extensive calculations were presented on the feasibility of thevarious wavelength options for collective ion Thomson scattering (CTS) in ITER. CTS would measure theconfined fast ions and specifically the alpha particles.
The parties reported steady progress for many diagnostic techniques that are relevant to a BPX. A productive progress meeting on ITER/BPX relevant diagnostic developments in the RF was held with many contributions reporting good progress, for example advances in the design of the divertor Thomson scattering system, development of vacuum photodiodes for soft X-ray tomography, and development of the waveguide andantennas for the microwave reflectometer. The Specialist Working Groups (SWG) reported good progress intheir specific fields since the previous meeting. The SWG on Radiation Effects was urged to further develop
the Radiation Effects Database. The charter for a new SWG on Beam-Aided Spectroscopy and NPA wasaccepted.
Since the 4th meeting of the Topical Group on Diagnostics, in total 34 new diagnostics have been added tothe International Diagnostic Database (IDD). In particular, the many new diagnostics added by the TORE
SUPRA team should be highlighted. The database, which is now password protected, contains information on239 diagnostics. Addition of information on new diagnostics and information updates for diagnostics that arealready in the database continue to be actively stimulated.
An outline proposal for the diagnostics sections in the Tokamak Physics Basis was discussed and the preliminary authorship for the various sections proposed.
It is proposed to hold the 6th meeting of the ITPA TG on Diagnostics at JAERI, Naka, in the week 16–21
February, 2004, with a second stage in San Diego immediately after the High Temperature Plasma
Diagnostics Conference (19–22 April). Dedicated sessions on ITER/BPX relevant diagnostic work in progressin Japan and the USA will be included. A special session on active spectroscopy for ITER/BPX devices willbe included in the meeting held in San Diego.

Participants at the Meeting5Both meetings ran very smoothly and the participants are grateful to the Ioffe Institute for its hospitality. They
