Abstract
Surface nanomanipulation is becoming an important part of the emerging nanotechnologies. Part of the process are controlled displacement, disociation and rearangement of various molecules with the goal to prepare nanostructures of a desired shape, composition and ultimately also properties. Such processes can only be performed with the use of a scanning tunneling microscope, operated at low temperatures and under extremely clean conditions, with the topography of the substrate controlled on an atomic scale and with the required extreme mechanical stability. Of greatest importance is the construction of the cryostat, which in addition to the extreme temperature (liquid helium temperature) and vacuum requirements (below 10-10 hPa) has to offer the rquired mechanical stability. Such cryostats are as a rule constructed on special order and adjusted to a particular instrument. The goal of the applied project is to construct a cryostat with all the required extreme characteristics, which might ultimately also represent a marketing possibility for the domestic knowledge.
