N2 - This work introduces optimization techniques for designing pulse-tube coolers with the focus on coolers of smaller size. Methods are presented to select two geometric design parameters: Pulse-tube length to regenerator length ratio, and system length to diameter ratio. The optimum values of these parameters are a function of the conduction heat loss down the tube walls, the regenerator effectiveness as a function of its length, and the pressure drop along the pulse tube. Results indicate that the optimum regenerator length/pulse tube length ratio increases with decreasing system length, and the optimum system length/diameter ratio increases with decreasing system volume.
