Abstract	A cylindrical oven whose axis is the axis of the 10 MHz quartz resonator (in HC 40 can) is studied. Thermal flux is canalized on its axis at a place where the thermistor is located. Thermal exchanges include conduction and radiation effects, reduced, however, by the use of a dual envelope. The oven is studied through a scheme which uses electric analogs, and results are obtained for external temperatures between -25 degrees C and +60 degrees C. The thermistor is located on the resonator can where temperature is very close to the turnover point. The analytical modeling uses oven symmetry. Thermal regulation design includes a frequency analysis between 0.001 Hz and 10 Hz, with a 60-dB gain. A response analysis to temperature steps and to linear temperature variation (0.5 degrees C/mn) is also performed. The thermal gain and dynamical behavior of oven electronics is deduced. Insertion of a correction network with phase advance in oven electronics yields a fast oven response. The oscillator improvements in space conditions are described.<>
