HEAT-PIPE OVEN - A NEW, WELL-DEFINED METAL VAPOR DEVICE FOR SPECTROSCOPIC MEASUREMENTS

A new, well-defined metal vapor device called the heat-pipe oven has been developed on the basis of the heat pipe, a heat conductive element designed by Grover and his co-workers in Los Alamos. It continuously generates homogeneous vapors of well-defined temperature, pressure, and optical path length. The vapor is confined by inert gas boundaries which remove the window problem and allow a direct pressure measurement without relying on vapor pressure curves. Due to the continuous evaporation and condensation the vapor purifies itself during operation. © 1969 The American Institute of Physics.
