“…Based on the above description, a time slice (t = 4.65 s) of the high plasma performance phase with ITB and heavy impurities accumulation was chosen to analyze to illustrate the key physics of the formation of n e , T i and V t ITBs and understand the core W transport for shot #71326. Other potentially useful experimental information in this work, including the radiated power density [81,82] as the power sink and kinetic profiles [68,69,[83][84][85], has been provided in figures 5 and 6 respectively. It should be noticed that there is no sawtooth in this shot #71326.…”

“…Recently, ITB discharges have been achieved in EAST [24][25][26][27]. In this paper, the turbulence in the plasma core before and after ITB formation is investigated for the first time using multichannel poloidal correlation reflectometry (PCR) [46] and density profile reflectometry (DPR) [47][48][49][50] in EAST. The remaining sections in this paper are as follows.…”

“…Ultra-wideband (UWB) antennas are an important research topic in antenna theory and are widely used in many fields, such as broadband ground penetrating radar, 1 UWB/WLAN applications, 2,3 biomedical detection, 4 and plasma microwavediagnostics. [5][6][7] Recently, UWB microwave diagnosis is an important trend in plasma reflection diagnosis. An ultrawide range of electromagnetic waves can increase the diagnostic range of plasma electron density.…”

“…An ultrawide range of electromagnetic waves can increase the diagnostic range of plasma electron density. 5 In the UWB plasma reflection diagnostic system, it is necessary to transmit and receive electromagnetic waves, and thus the UWB antenna is an indispensable component. Moreover, the UWB antenna needs a simple structure, the size is as small as possible, the performance is stable, and it is convenient to integrate with the electronic circuit.…”
