We have studied the cooling power of a Gifford-McMahon refrigerator by varying the phase lead of pressure relative to displacement oscillations of working helium gas. The increase of the size of spherical regenerator materials results in the increase in the optimum phase lead, which represents the poor thermal contact in the regenerator filled with large particles.
