摘要： The invention relates to an arrangement and method for damping vibrations during microscopic examinations of inorganic and organic material samples at low temperatures. The aim of the invention is to provide an arrangement for microscopically examining inorganic and organic material samples that are cooled by an electromechanical cryocooler, wherein the transfer of vibrations from the cryocooler onto the sample, the microscope table and the instrument table is suppressed. The solution to the problem is solved using an arrangement and a method for damping vibrations during microscopic examinations of samples in an evacuated measurement cell at low temperatures, said arrangement comprising a cryocooler unit (100) and a microscopy unit (200) that are combined with a damping unit (300) on a common longitudinal axis (21), the damping unit (300) having a series arrangement of inter-coupled evacuatable compensation chambers (310, 320, 330, 340) along the longitudinal axis (21), the series arrangement being combined with damper groups, two of which act at least diametrically. A tensioning unit (400) is operationally connected to the damping unit (300) at at least two points on the series arrangement. The method is characterised in that the damping unit (300) is subjected to adjustable pre-tensioning.
