We report mineral magnetic results from a 7.5 m loess sequence (150 samples) the southernmost extremity of Chinese plateau (which includes last two glacial cycles). In this area sediments experienced particularly intense weathering processes. The assemblage is dominated by mixture pseudo‐single domain (PSD) and multidomain (MD) magnetite with associated superparamagnetic (SP) grains either or maghemite in paleosols weathered horizons. All rock parameters fluctuate parallel marine sediment δ...
The Matuyama‐Brunhes (M/B) boundary, termination of Jaramillo normal subchron (J/M) as well three young geomagnetic excursions has been revealed in the Weinan loess section [ Zhu et al. , 1994 1998 1999 ]. Recently, we carried out further paleomagnetic directional studies on same and recovered onset (M/J) four excursions, two Brunhes late Matuyama. fact that all seven found this are units expected paleosols not suggests short‐lived signals could be only recorded units, may have fully...
Abstract Since the last IAEA-FEC in 2021, significant progress on development of long pulse steady state scenario and its related key physics technologies have been achieved, including reproducible 403 s long-pulse steady-state H-mode plasma with pure radio frequency (RF) power heating. A thousand-second time scale (∼1056 s) fully non-inductive high injected energy up to 1.73 GJ has also achieved. The EAST operational regime β P significantly extended ( H 98y2 > 1.3, ∼ 4.0, N 2.4 n e / GW...
Although the wind‐blown loess and interbedded paleosol sequence in Loess Plateau of China has been extensively studied regarded as one most complete terrestrial records both geomagnetic field climatic changes during Quaternary, little attention paid to it a source relative paleointensity. In this study, we examine Malan (L1), last glacial sediments, Lingtai section determine whether is able reliably record Toward that end conventional normalizing method well pseudo‐Thellier [ Tauxe et al. ,...
We have conducted a detailed mineral magnetic study of loess unit 8 (L8) and paleosol (S8) from three localities (Jingbian, Yichuan, Duanjiapo) along N‐S transect in the Chinese plateau. As expected, low‐field susceptibility (χ) has higher values S8 lower L8. Similarly, superparamagnetic particle concentrations increase with increasingly humid climates transect, which suggests that pedogenic enhancement is related to climate. However, at Duanjiapo, χ so low there no correlation between...
A high‐resolution paleomagnetic and rock magnetic investigation supported by scanning electron microscopy observations, X‐ray diffraction determinations, anisotropy of susceptibility analyses has been carried out on a loess‐paleosol sequence from Jingbian (37.4°N, 108.8°E), at the northern extremity Chinese Loess Plateau. The results indicate that assemblage is dominated pseudo‐single‐domain magnetite with associated maghemite traces higher‐coercivity phase, probably hematite....
A bridge arm prototype of ITER poloidal field (PF) converter modules has been designed and fabricated. Non-cophase counter parallel connection is chosen as the structure prototype. Among all factors affecting current sharing, main one. During design prototype, a novel method based on inductance matrixes employed to improve sharing arm. The test results show that performance much better than relevant requirement, matrix very effective analyze solve problems thyristor converters.
Three loess sequences located east of the Liupan mountain region, China, were studied to obtain records Blake polarity event. Palaeomagnetic from appropriate stratigraphic interval these three sequences, however, record event poorly in one case and not at all other two cases. It is important understand why miss event, whereas others it quite well. We conclude that regional variations sedimentary environment over Chinese plateau are responsible for inconsistent recording The palaeomagnetic...
This paper describes the coupled force and natural convection analysis technique to calculate increase in temperature of international thermonuclear experimental reactor poloidal field converter water-cooling dc busbar. The busbar is due Joule's losses heat dissipation by cooling water air convection. loss calculated 3-D eddy-current used as input for thermal fluid analysis. Energy conservation equation coded primary coefficient on external surface calculated. An interactive procedure...
Fusion power plants can meet the energy demands of world. The high thermal performance a generation system is still challenge and one developing trends with fusion reactor due to outlet temperature.

The tokamak cooling water system (TCWS) is the primary of ITER machine, providing to vacuum vessel and in-vacuum components. In addition, it provides gas baking its clients as well drying them prior maintenance activities. It a Safety Important System that subject French Order on Nuclear Pressure Equipment. TCWS design has been modified significantly since preliminary design. Such changes required approval Authority (ASN). first main modification was relocate equipment loop for in-vessel...
The DC busbar is an important component for the ITER PF converter module to connect and reactor. This paper analyzes different cross-sections thermodynamic properties under natural-cooling water-cooling conditions, simulation carried out by software of finite element method (FEM). result analysis shows that better choice busbar.
