Miller and R.G. Ross, Jr. ©¶International Cryocooler Conference, Inc., Boulder, CO, 2012 WebAiming to attenuate the vibration that is induced by a Gifford-McMahon (G-M) cryocooler, a method attenuating the vibration with mechanical vibration isolators (MVIs) is proposed. A scheme supporting the G-M cryocooler with one kind of supporting system that mainly comprises the MVIs is presented.
