Introduction

F4E is responsible for the in-kind procurement of the following:

Neutral beam heating system (100% assembly and testing, 100% beam line components, 100 % of compensation and active correction coils, around 50% of the remaining components broken down into:

• Neutral beam heating system assembly (3.8 kIUA); • Beam source and high voltage bushings (3.893

kIUA);

• Beamline components (3.9 kIUA); • Confinement and shielding (9.025 kIUA);

• Active corrections and compensation coils (4.4 kIUA);

• Heating and neutral beam power supplies (31.382

kIUA);

• Neutral Beam Test Facility (27 kIUA) approved

by the ITER Council as an additional direct investment.

Executive Summary

In the area of the neutral beam heating systems, the main highlights during 2012 are as follows:

• Many major procurement contracts for the

Neutral Beam Test Facility were signed in 2012

and the tendering procedures for many others were launched and progressed;

• The construction of the Neutral Beam Test Facility buildings at the Consorzio-RFX site in Padova started;

• Design work on towards the build-to-print

specifications of the heating neutral beam core components and front end progressed well, with the ITER Organization preliminary design review being successfully passed;

• The ELISE experiment in IPP entered into operation.

ITER Credit Status

Procurement arrangements for the neutral beam systems were signed in July 2009 and October 2010. In addition, credit has been awarded to F4E in both 2011 and 2012 for work completed.

Progress Report

The Neutral Beam Test Facility entered the construction phase in 2012, with the start of the works for the erection of the buildings in Padova. The buildings, managed by Consorzio RFX are part of the Italian contribution to the establishment of the Neutral Beam Test Facility.

In 2012, F4E continued to provide support to the ITER Organization to prepare the neutral beam technical specifications at the required level of detail. This support included most of the design and R&D activities related to the heating neutral beam system and the design and the establishment of the Neutral Beam Test Facility. In particular:

• The ITER preliminary design review for four of

the neutral beam front components (drift duct, VVPSS box, exit scraper and fast shutter) was approved successfully in 2012. The preliminary design review for the beam line and beam source vessel, the passive magnetic shield and active correction and compensation coils are foreseen for April 2013 final review in 2013 included.

• The design of the megavolt ITER injector and

concept advancement (MITICA) components was advanced: in March the preliminary design reviews of the neutral beam line components (neutraliser, electrostatic residual ion dump and calorimeter) and of the MITICA vacuum vessel were performed and all the components were accepted for the subsequent final design phase.

• An intense R&D activity was performed to verify

the applicable technology for the fulfilment of the stringent requirement of the high heat flux components.

• The test facility for ultra-high voltage tests for

vacuum insulation was fully commissioned and several experimental campaigns have been performed to verify electrostatic configuration of the beam source accelerator also in the presence of transversal magnetic field.

• Manufacturing activities for the ion source and

extractor power supplies (ISEPS) started in May and have been progressing well. The EGPS modules production started after successful prototyping, the prototyping and testing of the electronics is in progress (MFC control electronics, RAAD, PLC based controllers, and the development of the radio frequency generators by Himmelwerk is on-going. A quality assurance audit of the main supplier OCEM Energy Technology was conducted in November, with satisfactory results.

• The major contract for the procurement of the

SPIDER beam source and vacuum vessel was signed, being those are the core components of the SPIDER test bed.

• The technical exchanges held within the

competitive dialogue for the 1MV deck and bushing of MITICA and ITER injectors came to a successful conclusion in November in particular the critical interface with the SF6 transmission line provided by

the Japanese Domestic Agency. The procurement is now due to start soon. SPIDER high voltage deck and transmission line. The procurement is expected to start in the first months of 2013.

• The call for tender (negotiated procedure) for

the Neutral Beam Test Facility cooling plant was launched as foreseen in 2011, first offers were received in January 2012 and the contract was signed in September 2012.

• The contract for the procurement of the gas

storage and distribution, vacuum and gas injection systems for the Neutral Beam Test Facility was signed in December 2012.

The assembly of the Experiments of Large Radiofrequency Ion Source (ELISE) at the Institute of Plasma Physics (IPP) in Garching was completed

in November 2012 and during the same month the test facility was inaugurated celebrating the starting of the experiments. An ad-hoc group of experts has been appointed by F4E to constitute the ELISE Programme Advisory Committee (EPAC), whose mission is supporting the IPP team in preparing the experimental program and reviewing the results of the experiments.
