title: Numerical investigation of alpha particle confinement under the perturbation of Neoclassical Tearing Modes and toroidal field ripple in CFETR
title: Numerical investigation of alpha particle confinement under the perturbation of Neoclassical Tearing Modes and toroidal field ripple in CFETR

description: The confinement of alpha particles in burning plasma is a key issue in fusion reactor design, including particle interaction with instabilities. This paper includes two topics, one is the effect of Neoclassical Tearing Modes (NTM) and toroidal field ripple on alpha particle loss, and another is the assessment of particle redistribution under NTM with a reduced model. We consider Chinese Fusion Engineering Test Reactor (CFETR) parameters, the alpha particle distribution given by TRANSP/NUBEAM and the NTM perturbation function given by the initial value code TM1. We show the synergistic effect of NTM and ripple is negligible; the particle loss fraction does not change with increasing NTM amplitude. Only passing particles are affected by the mode particle resonance, producing profile flattening but no increased loss because only trapped particles are influenced by ripple. To study alpha particle profile flattening, the work adopts an innovative method of phase vector rotation to determine regions of good and broken Kolmogorov Arnold Moser (KAM) surfaces and equilibrates the particle density according to local stochasticity.

title: Data for “Deuterium pellet fueling in type-III ELMy H-mode plasmas on EAST superconducting tokamak”
title: Data for “Deuterium pellet fueling in type-III ELMy H-mode plasmas on EAST superconducting tokamak”

description: Recently, pellet fueling experiments have been successfully carried out on EAST, an ITER-like tokamak. A maximum electron density of 0.73×nGW has been obtained. It is found that ELM behavior was modified immediately and a string of small ELMs were induced when pellets were injected at a low velocity from ˜40 cm above the mid-plane on the low field side, which isdifferent from the fact that pellets trigger signal ELMs in Type-I ELMy H-mode plasmas in other tokamaks. The decreased edge temperature caused by the cryogenic pellet was proposed as the reason for this ELM modification.The data set contains the main data that support the above points.

title: The data set for "Measurement of velocity and reliability of 50 Hz pellet injector for EAST"

description: A high frequency, 50 Hz, pellet injection system (PI-50) based on screw extrusion forming ice and pneumatic acceleration has been built and developed for ELM mitigation for EAST. As velocity and reliability of launching frozen pellet are of importance to ELM mitigation, a diagnostic system including video cameras is installed on this pellet injection system to acquire the pellet's velocity and monitor the quality of pellet. With the help of this diagnostic system, the velocity and reliability of PI-50 system have been measured successfully. This data set contains the main data supporting the above points.

title: Data set for "Density compensation and stored energy recovery in resonant magnetic perturbation suppressed edge-localized mode H-mode plasmas using pellet fueling on EAST"

description: The fueling of plasmas using frozen pellets in steady-state quiescent H-mode plasmas with edge-localized modes (ELMs) suppressed by external magnetic perturbations (RMPs) wassuccessfully demonstrated on the EAST tokamak in plasmas with similar shapes to those in ITER with q95 ~ 3.8, and triangularity δ ~ 0.45. During the fully suppressed-ELM phaseusing RMPs, the plasmas were refueled by deuterium pellets with a frequency of 5 Hz from ~40 cm above the mid-plane on the low field side. The results show that the pellet fueling would partially compensate density, which decreased due to the effect of pump-out induced by RMPs. It was interesting to discover that the stored energy of the plasma could be raisedto the value from before RMP application using pellet injection, which is rarely reported in other tokamaks. As for ELMs, they reappeared with a size smaller than the ELMs before RMPapplication accompanied with a magnetic coherent mode termination, however, the ELMs were still mitigated to a certain extent. Meanwhile, a similar experiment using supersonicmolecular beam injection fueling was also carried out, which confirmed that pellet fueling is better for raising plasma stored energy. The data set contains the main data supporting the above points.

title: The code for ion energy distribution in a radio frequency sheath of plasma with Kappa electron velocity distribution
title: 关于在含有高能电子成分射频鞘中的离子能量分布的程序

description: Ion energy distribution is an important research direction in the field of radio frequency sheath. When there are high energy electrons in the RF sheath, the change of sheath potential will cause the dependence of ion energy distribution on the high energy electrons. To solve this problem, a one-dimensional collisionless RF sheath program with high-energy electronic components is developed. Based on the RF sheath model established by Edelberg and Aydil in 1999, the program assumes that the high-energy electronic components obey the Kappa velocity distribution, and makes changes in the program we wrote earlier [An, Ou, and Men, Plasma Sci. Technol. 22 (2020) 065103]. The program can be used to analyze the sheath structure of non - Maxwell electrons and the influence of disturbing current and frequency on sheath structure in the case of non Maxwell electrons. Then, the probability density function ksdensity of Matlab is used to obtain the ion energy distribution. The results of this program support published articles [Ou and Huang, Contribut. to Plasma Phys. 2021; 61: e202000108]

title: 存在超热电子的磁化射频鞘特性的程序

description: This program is based on the radio-frequency sheath model established by Edelberg and Aydil in 1999. It is assumed that the high-energy electronic components obey the Kappa velocity distribution, and we have made changes in our previous program [Ou and Huang, Contribute. to Plasma Physics. 2021; 61: e202000108]. The program can analyze the sheath sheath of non Maxwell electrons under different magnetic field intensities and angles, and the influence of disturbance current and frequency on sheath structure under non Maxwell electrons, but the program is not suitable for the case where the angle is less than 5 degrees. Then, according to the structural characteristics of RF sheath, we can analyze the ion energy distribution and other related issues. The results of this program support the published article [ou and Huang, Phys. Scr. 96 (2021) 125601]

title: ITER PF6 线圈双饼氦管的电学性能数据

description: The helium inlet is one of the most important components of the ITER Poloidal Field (PF) coils. The insulation structure of the helium inlet is critical to provide sufficient electrical and mechanical properties for a practical application. In this paper, an ITER PF6 coil double pancake helium inlet trial mock-up was designed and manufactured by simulating the actual manufacturing process. A thermal cycling test on the sample was carried out from 280 K to77 K, also before and after the thermal cycling, a turn-to-turn DC HV test and Paschen test were performed. The test results satisfied the ITER requirements. It has therefore been verified that the PF6 coil double pancake helium inlet insulation has good electrical properties, and can be applied to the formal production of the PF6 coil double pancakes.
