ABSTRACT	The 750kW arc-heated (or arc-jet) wind tunnel is equipped with a channel nozzle to evaluate flat plate TPS materials. TPS material tests for HOPE-X design data have been made with this channel nozzle, but the flow characteristics of the high enthalpy flow generated in the nozzle have not been well investigated. Therefore, flow diagnostic experiments have been planned. Experimental items included in the plan are emission spectroscopy, mass spectrometry, heat flux measurements, and thermometry and direct surface observations of the test materials. A new calibration module was designed to install the instrumentation necessary for the measurement of these items in the channel nozzle test section. The conception of the experiments, design details of the module and main experimental results are presented.
