Temperatures between 4 K and 1 K are obtained by pumping on a 4He bath. In order to reduce the consumption of liquid helium, it is common to pump only on a small volume of He inside a small chamber (1 K pot), continuously replenished from the main bath through an impedance. 1 K pots are a necessary cooling stage in dilution refrigerators, which are used to cool many different kind of sensitive detectors to temperatures in the mK range, e.g. gravitational antennas, bolometers for far-infrared radiation or high resolution particle detection. It is known that continuously filled 1 K pots are affected by vibrations that are a source of excess noise, and thus can decrease the performance of the detectors. We present our study on the origin of these vibrations and a solution we have found to eliminate this excess noise from the detectors. .
