The construction of an arc vessel designed to measure the axial profile of thermal wall loading in a vortex-stabilized arc lamp is described. The cooling jacket, which surrounds the quartz arc tube is made of glass and is partitioned so that the axial profile of wall loading can be measured by continuous flow calorimetry. A notable feature is that, if required, the inner tube can easily be removed and replaced. Procedures for the calibration of the calorimeter are outlined and checks which were made for systematic errors in the apparatus are also reported. A profile, obtained with the calorimeter, is presented for a 17-kW arc operating in argon at a pressure of 5 1/2 atm and with a dc current of 225 A.
