The development of 1 MW ECRH system on J-TEXT [PDF]

open access: yesEPJ Web of Conferences, 2023
A 1 MW electron cyclotron resonance heating system has been designed and developed for J-TEXT tokamak not only to enhance the total heating power but also to provide another possible way to control the plasma parameters.

Plans for the electron cyclotron heating system on J-TEXT [PDF]

open access: yesEPJ Web of Conferences, 2019
A new 105 GHz/500 kW/1 s electron cyclotron resonance heating (ECRH) system has been designed and being constructed on J-TEXT Tokamak. This system mainly consists of a microwave source, a transmission line, a launcher and other auxiliary units.

Critical switching current density of magnetic tunnel junction with shape perpendicular magnetic anisotropy through the combination of spin-transfer and spin-orbit torques

open access: yesScientific Reports, 2021
Recently, magnetic tunnel junctions (MTJs) with shape perpendicular magnetic anisotropy (S-PMA) have been studied extensively because they ensure high thermal stability at junctions smaller than 20 nm.

Observation of X(2370) and search for X(2120) in $$J/\psi \rightarrow \gamma K{\bar{K}} \eta '$$ J/ψ→γKK¯η′

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Using a sample of $$1.31\times 10^{9} ~J/\psi $$ 1.31×109J/ψ events collected with the BESIII detector, we perform a study of $$J/\psi \rightarrow \gamma K{\bar{K}}\eta '$$ J/ψ→γKK¯η′ . X(2370) is observed in the $$K{\bar{K}}\eta '$$ KK¯η′ invariant-mass

Upgrade of vacuum ultraviolet spectroscopy system on J-TEXT tokamak [PDF]

open access: yesReview of Scientific Instruments, 2021
The vacuum ultraviolet (VUV) spectroscopy system on the Joint Texas Experimental Tokamak has been upgraded to achieve fast acquisition for the study of impurity transport in transient modulated experiments. In this upgrade, the previous high-energy charge-coupled device detector was replaced by a microchannel plate with a CsI-coated photocathode and ...

First measurement of the $$C\!P$$ C P -violating phase in $${{B} ^0_{s}} \!\rightarrow {{J /\psi }} ($$ B s 0 → J / ψ ( $$\rightarrow $$ → $$e ^+e ^-$$ e + e - ) $$\phi $$ ϕ decays

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
A flavour-tagged time-dependent angular analysis of $${{B} ^0_{s}} \!\rightarrow {{J /\psi }} \phi $$ B s 0 → J / ψ ϕ decays is presented where the $${J /\psi }$$ J / ψ meson is reconstructed through its decay to an $$e ^+e ^-$$ e + e - pair.
