First bushing ring for neutral beam produced

22 May 2009 - Sabina Griffith
Takashi Inoue (Japan Atomic Energy Agency, JAEA) and Masanobu Tanaka (ITER) proudly present a prototype of the ceramic bushing ring for the ITER neutral beam heating system.

A prototype of the five bushing rings that serve as insulators on ITER's neutral beam heating system has been produced at KYOCERA Corporation and passed testing of the metalizing/brazing process at Hitachi Haramachi Electronics Company in Japan.

The bushing rings connect the high pressure transmission lines for the 1 megavolt power supply with the vacuum chamber inside the neutral beam system. The rings are made of a special ceramic (alumina) with conductor plates brazed for the electrical connections and measure 1.46 metres in diameter.
