METHODS FOR LOW POWER TEMPERATURE CONTROL.
Abstract
An investigation was made of methods, techniques, and devices by which the temperature of a quartz crystal can be maintained, with a minimum of power, at a nominal operating temperature over environmental temperature extremes. The work includes investigation of second-order effects applicable to the design of low-power crystal ovens. End products resulting from the study are three types of ovens: a 3-cu in., 500-milliwatt oven (Type J6) requiring accessibility to the crystal and operating at +75 C = 1 C over a -55 C to +60 C ambient; a 3-cu in., reduced power, sealed oven (Type K6G) with similar operating requirements; and a 4-cu in., 250-milliwatt oven (Type L6) requiring accessibility to a chamber capable of housing two crystals and operating at 0 C = 1 C over a -55 C to 0 C ambient.
