System for cooling a sample in a device for processing the sample

To the cooled processing a sample, a system for cooling the sample has a holding means (22) for receiving the sample in a sample holder (20) and a cooling chamber (12) surrounding the position (P) of the mounted on the holding device sample. The holding device (22) is cooled by means of a fluid coolant to an adjustable temperature and provides cooling of the sample. For this purpose, a coolant flows, eg. As liquid nitrogen, through a coolant channel (24) of the holding device (22) which is fed on the input side (31) with the coolant and the output side (41) opens into the cooling chamber (12) which is filled in this way with refrigerant gas , In addition, the holding means (22) on a pivot arm (21) for pivoting the sample is placed. The cooling chamber (12) together with the swivel arm forms an attachment, which is detachably via a connecting interface (17) can be mounted, wherein the tool holder (16) for processing the sample through a window (47) in the connection interface (17) (in the cooling chamber 12 ) projects.
