title: Diode End-Pumped 1.37 W Er:YSGG Continuous-Wave Laser Around 2.8-µm

description: We demonstrate the laser performance of a LD end-pumped Er:YSGG crystals with different doping concentrationscomparatively. The experimental results show that 30 at. % Er:YSGG crystal with dimensions of 2 mm × 2 mm × 8 mm has the best laser output. In continuous-wave (CW) mode and pulse mode, the maximum output powers of 1.37 and 1.20 W are achieved, corresponding to slope effificiencies of 23.62% and 22.91%, respectively. To the best of our knowledge, compared with other Er3+-doped garnet laser crystals, we obtained a larger power and higher effificiency CW laser simultaneously for LD end-pumped Er:YSGG crystal. The beam quality factor M2 in x and y directions are determined to be 1.64/1.65, suggesting the Er:YSGG laser possesses a higher beam quality. All these results indicate that Er:YSGG is a promising mid-infrared gain medium for high effificiency and high power laser operation.

title: Design of Langmuir probe diagnostic system for the upgraded lower tungsten divertor in EAST tokamak

description: In order to achieve long-pulse H-mode plasma scenario over 400 s with high heating power in the Experimental Advanced Superconducting Tokamak (EAST) device, the lower graphite divertor will be upgraded into a tungsten (W) divertor with active water cooling, which consists of theW/Cu monoblock units and the W flat-tile units as the divertor plasma facing components. As a fundamental diagnostic tool, the divertor Langmuir probe (Div-LP) diagnostic system will be upgraded accordingly. This paper presents the design of two kinds of new Div-LP systems, which are planned to be utilized on the W/Cu monoblock units and the W flat-tile units for the upgraded lower tungsten divertor, respectively, including their structures and preliminary poloidal and toroidal layouts. The Div-LP diagnostic system can measure the plasma parameters with the schemes of triple-probe, double-probe, and single-probe, to obtain the spatial and temporal distribution of plasma behavior on the divertor targets, which is useful for the discharge control and operation in EAST. In addition, the thermal analysis of the two kinds of probe assemblies is also carried out by using the three-dimensional finite element code ANSYS, which is aimed to get the optimal designs to withstand the long-pulse and high-power operation in EAST future experiments.

title: Comparison of measurements with different types of divertor Langmuir probe in EAST tokamak

description: Divertor Langmuir probes (Div-LPs), embedded in the divertor target plates, are the important diagnostic tools to measure the plasma parameters in EAST divertor region. A series of measurement methods, i.e., single-probe, double-probe and triple-probe schemes, are applied and compared for the Div-LPs on EAST, to get the electron temperature Te and the electron density ne at the same poloidal position, respectively. It is found that the electron temperature Te and the electron density ne measured by the single-probe and the double-probe schemes are basically the same during the plasma discharge phase. Further analysis of the electron energy distribution function (EEDF) represented by the first derivative curve method shows that the electrons conform to a Maxwell distribution, which indicate that the three methods can be applied in the EAST divertor region. Besides, the domed and flush-mounted probe tips for measuring the plasma parameters are also compared, and the results show a good match. The sheath potential coefficient Λ is also calculated from the I-V characteristic curves by two ways, i.e. Λp = (Vplasma-Vf )/Te and ΛI = ln(|Ies/Iis |), and compared with the traditional value Λ = 2.8, the results indicate that the ∼1.5ΛI and Λ = 2.8 are available to replace the Λp under the different strength of toroidal magnetic field in EAST tokamak.

title: The Eye Movement Data of Chinese Children Aged 1-6 Years of Free-Viewing Paragim

description: Eye movement of Hidden Markov Model is used to explore the characteristic of eye movement patterns in Chinese children aged 1-6 years when completing the free-viewing face paradigm and to investigate the relationship between eye movement patterns and children's cognition. We found that children exhibit holistic and analytic eye-movement patterns. As the age-group advanced, the change of the eye-movement patterns for different faces was similar. The likelihood that children in each age group would adopt the same eye-movement patterns was higher among groups than within groups. In addition, our research demonstrated a clear relationship between eye-movement patterns and cognitive abilities in children, and this relationship was more pronounced in the toddler group. Children exhibiting analytic patterns showed better performance compared with those exhibiting holistic patterns. Children with an analytic pattern may engage in both local and global processing, whereas participants with a holistic pattern may primarily engage in global processing. We discuss potential underlying mechanisms and suggest that the potential application of eye tracking as an efficient method for the early detection of cognitive abilities and neurodevelopmental disorders in infants and young children.

description: A passive and noninvasive diagnostic system based on high-frequency B-dot probes (HFBs) has been designed and developed for the measurement and identification of ion cyclotron emission (ICE) in the Experimental Advanced Superconducting Tokamak (EAST). Figures for ICE signals corresponding to the fundamental cyclotron frequency of hydrogen ions and harmonics of deuterium ions were observed in experiments where deuterium plasmas were heated with deuterium-neutral beams had been updated. The field dependence of ICE has been verified by recent experiments with three different background magnetic fields. The figures record: 1. the relationship between ICE frequency and background magnetic field; 2. the spectrum of ICE during NBI operation;3. the edge and core ICE detected in EAST tokamak.

title: Upgrade Design of Lower Divertor Langmuir Probe Diagnostic System in the EAST Tokamak
title: Upgrade Design of Lower Divertor Langmuir Probe Diagnostic System in the EAST Tokamak

description: A flush-mounted Langmuir probe system has been built on the lower graphitic divertor targets in the experimental advanced superconducting tokamak (EAST) in 2016, which is revised from the previous divertor Langmuir probes, aimed to reduce the erosion from high-energy particle and strong heat flux on the probe surfaces exposed in the plasma, and explore new structure applications. The theories of single and triple flush-mounted probes relevant to their dimensions and the plasma parameters in the EAST divertor region are reviewed. During the 2016 EAST campaign, the flush-mounted probe system measured the plasma parameters by using single and triple probes, respectively, to obtain plasma parameters. The results were compared with the previous measurements by the domed probe in the similar condition. The results showed a good agreement between measurements using different probe geometries and techniques. This demonstrated the reliability of the flush-mounted probe system as a diagnostic tool in the EAST divertor. Optimization of these Langmuir probe system for the next generation of EAST lower divertor, which will be upgraded to a full tungsten divertor with active water cooling, is also discussed.

title: Rotation braking with n = 1 nonaxisymmetric magnetic perturbation in the EAST tokamak
title: Rotation braking with n = 1 nonaxisymmetric magnetic perturbation in the EAST tokamak

description: The toroidal plasma rotation braking effect during the application of n = 1 static resonant magnetic perturbation is studied by momentum transport analysis in the EAST tokamak. The braking torque shows a global profile and two peaks located near the plasma core and the edge, respectively. The effect of momentum diffusion contributes significantly to the calculated torque. Simulation results with the obtained torque and momentum diffusion coefficients well reproduce the observed plasma rotation evolution. Neoclassical toroidal viscosity (NTV) torque is modeled for comparison with the experimental torque. The total integrated NTV torque is around −0.12 Nm, which is comparable to the observed braking torque (around −0.33 Nm). In the plasma edge, there is a peak in the NTV torque profile, which agrees well in amplitude with the obvious peak in the observed torque density profile. An additional peak in the NTV torque profile due to the ion bounce resonance is also located in the core region. However, the magnitude of this peak is much smaller than the observed one near the plasma core.
