其它 | For the preparation of cryogenic fuel layer in inertial confinement fusion experiments, the vibration amplitude of cryogenic target must be reduced to the order of 1 mu m or less to ensure the fuel layer to be distinguished by the Xray phase contrast imaging system. An efficient vibration-reduction system with the Gifford-McMahon cryocooler mounted at the horizontal direction is designed, which is based on a two-stage floating thermal shielding and flexible connection. The obtained lowest temperature of the sample mount is less than 10 K, the temperature stability is within +/- 1 mK@18 K, the cooling power is greater than 500 mW, and the corresponding vibration amplitude is less than 1 mu m. |
