Superheating in the heat-pipe oven

This paper presents a device which modifies the heat-pipe oven in such a way that the molecular number density can be drastically reduced. The device is essentially a small chamber with a independent internal heater inserted in the center of the ordinary linear heat-pipe oven , which serves in turn as a reservoir of the liquid metal. The advantage of this design of superheating within the heat-pipe oven where temperature differences of several hundreds degrees centigrade were obtained, is shown in the case of far blue wings of the first self-broadened potassium resonance lines
