Times Cited Count:7 Percentile:41.4(Engineering, Electrical & Electronic)The Central Solenoid (CS) of the ITER magnet system will play a major role in tokamak operation, providing not only the major part of the inductive flux variation required to drive the plasma but also contributing to the shaping of the field lines and to vertical stability control. To meet these requirements, the design has been optimised by splitting the CS into six independently powered coils enclosed inside an external structure which provides vertical precompression thus preventing separation of the coils and, additionally, acting as a support to net resulting loads. To ensure that the CS design meets the ITER criteria, several analyses are performed along with a series of R&D trials to qualify the technologies to be used for the manufacture of the conductor, the coils and the structure.

The LOH (loss of heterozygosity) induction by various ion beam radiations was investigated in diploid . The ion beams C, C, He and Ar at the lowest dose (75, 75, 200 and 150 Gy, respectively), which had 3050% lethality, induced LOH with 10-fold higher frequency. The LOH induction was predominantly (90%) resulted from homologous recombination. Pol may be involved in the induction of LOH by ion beam radiations, because in the strain lacking Rev3, only slight induction of LOH was observed. In addition, the effects of 14 herbal extracts were examined on iron-beam radiation induced LOH, and ethanol extract of possessed inhibitory effect on LOH induced by C ion-beam radiation with the manner dependent on doses of extract.
