Abstract
Development of instrumentation to measure high heat-flux levels (≥ 1.0 MW/m2 ) is described. Progress has followed the provision of arc-image thermal irradiation facilities of power inputs between 2-30 kW. Fact response radiometers have been constructed and after - calibration against an absolute calorimetric measurement used to indicate incident radiant intensity. Constantan-foil disc radiometers can confer a high degree of spatial as well as temporal resolution with a high degree of precision. Delicate disc-centre thermocouple joints were necessary as well as robust peripheral welding to a cold solderless junction. About ten different coating blacks have been assessed for burn-off tendency over the linear region of response, up to thermal intensities of 5.0 MW/m2.
