The Cryo Vibration Isolation Platform (CVIP) is a passive vibration isolation platform with z, Rx and Ry attenuation of floor vibrations (read our application note on Z-Transmissibility Measurements). It is placed directly on the cryostat cold plate and carries the experiment. It is a relatively stiff spring design, which results in atypical high cut-off frequencies and high payload. Although this will limit the damping of low frequencies, compared to conventional dampers with low cut-off frequencies, it is much more insensitive to added cables and thermal braids between cold plate and experiment. These can become the limiting factor for stability in conventional dampers.

HV rated positioners can realistically be considered compatible with pressures as low as 1E-8 mbar. Lower pressures can be achieved by prolonged baking of positioners in vacuum at 100-150 deg C, depending on the type of positioner. Upon request JPE can provide such service at additional costs.
