New inductively coupled plasma (ICP) heated wind tunnel (so-called Plasmatron) was designed and constructed in National Aerospace Laboratory of Japan (NAL). By utilizing this ICP-heated wind tunnel, surface catalytic effect on TPS can be evaluated more accurately. Designed maximum power is 110kW and maximum flow rate is 6g/s. Inner diameter of the plasma torch is about 75mm made of quartz tube. It is attached to the test section of the existing NAL/NASDA 750kW arc-heated wind tunnel by exchanging the arc-heater to ICP torch. This new facility has been started to operate with subsonic flow and initial data of the performance of the wind tunnel were obtained. Maximum heat flux was about 1MW/m^2 in air plasma at 90kW and 10kPa. This heat flux is sufficient for the catalytic tests of TPS, and it is confirmed that this tunnel is useful for the heating tests.
