Characterization of anti-vibration technology at cryogenic temperatures

Master thesis | Physics (MSc)
In this work, a near-zero stiffness mechanical filter is designed for use in STMs in a cryogenic environment. The filter is a Geometric anti-spring (GAS) filter which consists of a set of blades with a payload attached. This design allows for a low resonance frequency of 0.27 Hz and thus a low cutoff frequency in terms of filtering. First, a theoretical model is described in order to determine the relevant properties of the filter and its approximate workings. Second, the model was experimentally verified. From this, the resonance and damping of the filter were found. A limited amount of vibration measurements were also done to check if the filter is functioning as expected, however, due to instrumental limitations this was not conclusive.
