A particle beam apparatus has a cooled anti-contaminator ( 18 ) and/or a cooled specimen holder ( 17 ). A thermal conductor ( 19 ) is provided for providing a connection between the anti-contaminator ( 18 ) and/or the specimen holder ( 17 ), on the one hand, and the cooler ( 21 ) of a cryogen vessel ( 20 ) on the other hand. The thermal conductor ( 19 ) includes a carbon fiber bundle. With the carbon fiber bundle ( 19 a, 19 b), a high thermal conductivity is ensured between the cooler ( 21 ) and the surface ( 17, 18 ) to be cooled. At the same time, thermal expansions are avoided which lead to a displacement of the anti-contaminator ( 18 ) and/or the specimen holder ( 17 ).
