QUEST研究了球形托卡马克在受控PWI和电子伯恩斯坦波电流驱动下的稳态运行。QUEST的主要目的之一是实现MW级注入功率的长时间放电。因此，QUEST应在热量和颗粒处理方面具有挑战性的区域内运行。为了进行粒子处理，计划使用高温全金属壁（高达623 K）和封闭偏滤器，以实现循环比R = 1下的稳态操作。这是对DEMO的一次验证，因为从氚滞留的角度考虑，壁面泵浦应尽可能避免。QUEST项目将以增量的方式进行开发，如：I.在限制器配置中的低β稳态操作，II.偏滤器构型中的低β稳态运行，III.在闭合偏滤器配置中的相对高β稳态操作。项目的第一阶段对应这两年，第一阶段的最终目标是使全电流驱动等离子体达到20 kA。第二阶段将设计和测试封闭偏滤器。QUEST从10月开始运行，2008年，第一个结果。
QUEST focuses on the steady state operation of the spherical tokamak by controlled PWI and electron Bernstein wave current drive. One of the main purposes of QUEST is an achievement of long duration discharge with MW-class injected power. As the result, QUEST should be operated in the challenging region on heat and particle handling. To do the particle handling, high temperature all metal wall up to 623 K and closed divertors are planned, which is to realize the steady-state operation under recycling ratio, R = 1. This is a dispensable check to DEMO, because wall pumping should be avoided as possible in the view of tritium retention. The QUEST project will be developed in increment step such as, I. low β steady state operation in limiter configuration, II. low β steady state operation in divertor configuration, III. relatively high β steady state operation in closed divertor configuration. Phase I in the project corresponds to these two years, and final goal of phase I is to make full current drive plasma up to 20 kA. Closed divertor will be designed and tested in the Phase II. QUEST is running from Oct., 2008 and the first results are introduced.
