Kainic acid (KA) administration is known to cause seizures and neuronal death in the hippocampus. High-frequency stimulation (HFS) of the hippocampus can be a promising method in the treatment of epilepsy while the mechanism of action is unknown yet. It remains unknown whether HFS is neuroprotective for hippocampal neurons following KA-induced seizures in(More)
A new multi-channel poloidal correlation reflectometry is developed at Experimental Advanced Superconducting Tokamak. Eight dielectric resonator oscillators with frequencies of 12.5 GHz, 13.5 GHz, 14.5 GHz, 15 GHz, 15.5 GHz, 16 GHz, 17 GHz, and 18 GHz are used as sources. Signals from the sources are up-converted to V band using active quadruplers and then(More)
Recently, the stationary high confinement operations with improved pedestal conditions have been achieved in DIII-D [K. H. Burrell et al., Phys. Plasmas 23, 056103 (2016)], accompanying the spontaneous transition from the coherent edge harmonic oscillation (EHO) to the broadband MHD turbulence state by reducing the neutral beam injection torque to zero. It(More)
