Design of the supporting platform for low temperature UHV STM microscope
 Dao, Tomáš ; Křupka, Ivan (referee) ; Pavera, Michal (advisor)
Diploma thesis deals with the design of a vibration isolated platform for low temperature scanning tunneling microscope working under ultra high vacuum (UHV STM). Cooling of the microscope is done by liquid helium using a flow cryostat designed in Institute of Scientific Instruments of the AS CR. In the thesis, general requirements of designing of an ultra high vacuum compatible devices are discussed, as well as the ways of vibrational isolation and damping. Also some ways how to restrict the transfer of vibration between vacuum devices and surroundings are mentioned. This knowledge is then applied to the design of the antivibrational microscope platform compatible with low temperature usage. For better understanding of vibrational transfer and damping, a real model of the designed platform is made and vibrational transfer characteristics are measured and compared with the theory.
