AB - Construction of the SuperKEKB has been progressed in KEK. The target luminosity of the SuperKEKB is 8×1035 cm⁻²s^{−1}, which is 40 times larger than the KEKB. The vertical beam sizes of electron and positron must be squeezed to the level of 50 nano-meter at the interaction point. The beam final focus system for the SuperKEKB consists of 4-superconducting (SC) quadrupole doublets, 43 SC-correctors, 4 SC-compensation solenoids. The designs of the cryostats in the left and right side with respect to the beam interaction point are being studied with the progress of the magnet designs. In the design works, the support structure of each cryostat, strength of the cryostat components and support rods for supporting cold mass are investigated. As for the vibration issue, vibration properties of the superconducting quadrupole magnets due to the ground motion has been studied. Also vibration properties of the concrete bridges where the two cryostats will be placed in the interaction region were investigated and measured. We will present the cryostat designs and these vibration studies in this paper.
