The purpose of this project is to design, construct and evaluate two types of miniature low power ovens for regulating the temperature of quartz crystals. The temperature of the ovens is to be controlled by a proportional sensing system, and the crystals are to be accessible. One type of oven, the M6, is to maintain one HC6u crystal at some preset temperature between 80C. and 90C. to within plus or minus .2C. over an ambient temperature range of -55C. to 75C. The volume of this oven cannot exceed 3 cubic inches and the maximum average power delivered, 400 mw. The N13 oven is to maintain two HC6u crystals at some preset temperature between 0C. and 5C. to within plus or minus .2C. over an ambient range of -55C. to -15C. The volume of this oven cannot exceed 5 cubic inches, and the maximum average power delivered, 150 mw. The M6 oven must reach operating temperature in 10 minutes and the N13 oven, within 3 minutes. Both ovens can utilize up to 3 watts for rapid warm-up. Author
