Abstract : To effectively utilize an arc-imaging furnace as a source of controlled thermal energy, the flux density received at the sample must be known. A commercially available, double-elliptical, arc-imaging furnace has been calibrated using both an integrating calorimeter and a discriminating radiometer. The results show the thermal flux received over both a 0.9-mm-diameter area and a 9.5-mm-diameter area as a function of three-dimensional position within the receiving zone. In addition, flux contour maps are presented for several appropriate planes in the focal zone. The effects of rotating interrupter shutters on both heat flux and optical temperature measurements are discussed.
