Abstract
Cryogen-free dilution refrigerators are getting popular for rare event searches underground due to their advantages. However, the application of a pulse tube refrigerator introduces mechanical vibration that can translate into temperature fluctuation for calorimeters. The effect is significant in particular when the sensor is attached to a large absorber. A mechanical filter is installed to isolate the calorimeters from the vibration inside a cryogen-free dilution refrigerator while meeting thermal requirements.
