Abstract
The reservoir system includes a heater coil having electrical leads adapted to be coupled to a voltage source. The heater coil is adapted to generate heat in correspondence with a heater voltage provided by the voltage source. A reservoir material layer is adapted to regulate pressure of a gas disposed within the gaseous-discharge device in accordance with temperature of the reservoir material. Heat is transferred from the heater coil to the reservoir material through a series of thermally conductive layers in which each of the layers have different thermal conductivity and coefficients of expansion. As a result, the thermal path resistance between the heater coil and the reservoir material layer increases as temperature of the heater coil increases so that the reservoir material increases in temperature at a slower rate than the heater coil.
