![]() Dr. Shishir P. Deshpande, Project Director of ITER-India and Dr. Norbert Holtkamp, Principal Deputy Director-General of the ITER Organization signing the In-Wall Shielding PA. Others in the picture from left to right are Akko Maas, Yusuke Tada, Guenter Janeschitz, Peter Swenson, Indranil Bandyopadhyay, Haresh Pathak (IWS Responsible Officer) and Vinay Kumar. In-wall shielding consists of about 9000 blocks made out of borated steel and ferromagnetic steel. The blocks will fill the space between the double walls of the ITER vacuum vessel and will perform the dual role of absorbing the neutrons generated by the fusion reaction within the plasma and reducing the toroidal field ripple, a periodic variation of the toroidal field from its nominal value. << return to Newsline #101 |
