A new scintillator-based fast ion loss detector (FILD) has been installed on Experimental Advanced Superconducting Tokamak (EAST) to investigate the fast ion loss behavior in high performance plasma with neutral beam injection (NBI) and ion cyclotron resonance heating (ICRH). A two dimensional 40 mm × 40 mm scintillator-coated (ZnS:Ag) stainless plate is mounted in the front of the detector, capturing the escaping fast ions. Photons from the scintillator plate are imaged with a Phantom V2010 CCD camera. The lost fast ions can be measured with the pitch angle from 60° to 120° and the gyroradius from 10 mm to 180 mm. This paper will describe the details of FILD diagnostic on EAST and describe preliminary measurements during NBI and ICRH heating.
一个基于闪烁体的新型快离子损失探测器（FILD）已安装在实验先进超导托卡马克（EAST）上，用于研究在中性束注入（NBI）和离子回旋共振加热（ICRH）的高性能等离子体中的快离子损失行为。一个二维40毫米×40毫米涂有闪烁体（ZnS:Ag）的不锈钢板安装在探测器前方，用于捕获逃逸的快离子。来自闪烁体板的光子由Phantom V2010 CCD相机成像。可以测量损失的快离子，其俯仰角范围为60°至120°，回旋半径范围为10毫米至180毫米。本文将描述EAST上FILD诊断的详细情况，并描述在NBI和ICRH加热期间的初步测量结果。
