Abstract

An apparatus for use in material sublimation includes a hollow reservoir having thermally conductive walls. A piston is disposed between the sealed end and the ported end of the reservoir, and is in sliding contact with the walls of the reservoir. The piston has holes passing there through. A force generator is coupled to the piston for applying a continuous force to the piston wherein the continuous force biases the piston towards the sealed end of the reservoir.
