摘要:Proton precession magnetometer is a high-precision device for weak magnetostatic field measurement. The measurement accuracy depends on the frequency measurement of free induction decay (FID) signal, while the signal to noise ratio (SNR) is an important factor affecting the resul...

摘要:222Rn and 220Rn can be used as tracers of groundwater or submarine springs, and 222Rn in water also could indicate indoor radon problems in some regions. The half-life of 222Rn is long enough that its concentration may remain signi...

摘要:The influences of electrode biasing (EB) on toroidal rotation and turbulent (toroidal) momentum transport at the plasma edge have been experimentally studied in the J-TEXT tokamak. In the absence of bias (i.e. the bias current I b = 0 A), plasma toroidal rotation ...

摘要:The in–out divertor asymmetry in the Experimental Advanced Superconducting Tokamak (EAST), as manifested by particle fluxes measured by the divertor triple Langmuir probe arrays, is significantly enhanced during type-I edge localized modes (ELMs), favoring the inner divertor...
