A resonator set in a gap type holder in vacuum is connected to a radio frequency monitor and excited at 200 kHz of its second overtone at room temperature. The measurement is nerformed by sweeping the exciting frequency from the computer-controlled measurement system at a step of lmHz over about 1.3 Hz around the resonant frequency. A maximum Q-value of 2.2×10^7 is obtained by processing the data acquired from the measurement of the resonant curve of the resonator. This surpasses by 10% of the value estimated by Mason in Physical Acoustics, Vol. 1, Part A, p. 335, Academic Press, 1964.
