A Gram-positive, non-motile, white-pigmented, short rod actinobacterium, designated YIM 90734T, was isolated from a saline soil sample collected Ganjiahu Suosuo Forest National Nature Reserve in Xinjiang province, north-west China, and its taxonomic position investigated by using polyphasic approach. Strain 90734T grew optimally at 28–37 °C pH 6.0–8.0 5 % (w/v) NaCl. The peptidoglycan type A4α, l-Lys–l-Ala–l-Glu tyvelose mannose were the major cell-wall sugars. predominant menaquinones MK-10...
Mastering nuclear fusion, which is an abundant, safe, and environmentally competitive energy, a great challenge for humanity. Tokamak represents one of the most promising paths toward controlled fusion. Obtaining high-performance, steady-state, long-pulse plasma regime remains critical issue. Recently, big breakthrough in steady-state operation was made on Experimental Advanced Superconducting (EAST). A with world-record pulse length 1056 s obtained, where density divertor peak heat flux...
A comparison of the ASDEX Upgrade 3-strap ICRF antenna data with linear electromagnetic TOPICA calculations is presented.The substantiates a reduction local electric field at radially protruding plasma-facing elements as relevant approach for minimizing tungsten (W) sputtering in conditions when slow wave strongly evanescent.The measured reaction time-averaged RF current limiters to feeding variations less sensitive than predicted by calculations.This likely have been caused temporal and...
Abstract Tungsten (W) is one of the most promising plasma-facing materials for future fusion devices. Although its melting point highest among all metals, it still has great risk under extremely high plasma heat fluxes, which a big concern ITER and reactors. Actively cooled W components (PFCs) with both monoblocks flat-type structure have been successfully installed in lower divertor EAST tokamak since 2021, provide good opportunity direct comparison damage mechanism two types PFCs. Various...
Under varying working conditions, the failure prediction model for same type of equipment often proves ineffective in its deployment and application. Aiming to address limitations current fault diagnosis models based on neural networks, such as limited depth, insufficient feature extraction ability, lack adaptive poor classification effectiveness various domains, a novel algorithm called deep adaption residual network (DARN) was studied proposed. The incorporates pretraining enhance...

JET ITER-like wall, produces about 20% less main chamber radiation old A2 antennas. However...
The design, calibration, and installation of disruption halo current sensors for the Experimental Advanced Superconducting Tokamak are described in this article. All Rogowski coils that surround conducting structures, all signals analog integrated. Coils with two different cross-section sizes have been fabricated, their mutual inductances calibrated. Sensors installed to measure currents several parts both upper divertor (tungsten) lower (graphite) at toroidal locations. Initial measurements...
Experimental Advanced Superconducting Tokamak (EAST) Technical Diagnostic System (TDS) is used to monitor the outlet temperature of all superconducting coils; in case a anomaly, it will trigger safety interlock system meet EAST device requirements. The data acquisition TDS (TDS_DAQ) charge continuous DAQ nitrogen and helium signals, security alarm, long-term storage. TDS_DAQ has several functions: 1) DAQ, which includes DAQ. based on PCI eXtensions for Instrumentation technology obtains from...
During the smooth running of EAST (Experimental Advanced Superconducting Tokamak), a perfect network management system guaranteeing robust is important. In present complex infrastructure, it daunting task to manage all devices manually in and make sure they are not only up but also performing optimally.
