Given that ECRH enhances RE generation, it is crucial to assess whether subsequent mitigation techniques such as shattered pellet injection (SPI) with impurities like neon remain effective under these heated conditions. Pure neon injection could increase the RE current dissipation through pitch-angle scattering due to collisions with impurity ions. This study on J‑TEXT examines RE plateau formation triggered by argon massive gas injection and its dissipation by neon SPI, aiming to clarify the impact of on‑axis ECRH on disruption and dissipation dynamics.

This process gives rise to novel quantum phenomena distinct from conventional photoionization processes. Our results show that vortex photons carrying very small total angular momentum (typically zero or minus one) exhibit sensitivity to the magnetic moments of Rydberg atoms, especially those in circular Rydberg states, thereby establishing them as a possible spectroscopic probe of Rydberg magnetism. It is further shown that the initial photon energy plays a crucial role in obtaining significant experimental results, as a strong dichroism effect requires larger initial photon energy.
