MBE PRO 753-V01/Oct10 UHV STM 1_210V02_Jan/06 UHV STM 1 The legendary STM developed by Omicron. Unsurpassed stability and resolution Eddy current damping UHV sample/tip exchange In-vacuum I/V converter UHV STM 1 scanner for unsurpassed stability and resolution. More than 200 instruments have been delivered and successfully installed around the world since the development of the UHV STM 1 in 1987. The Omicron UHV STM 1 is the benchmark for easy, reliable and high-performance STM measurements in UHV. The volume of our customers’ research results and publications is nal proof of the unbeatable performance and quality of the design. The popularity and ease of operation of the UHV STM 1 has lead to it gaining the reputation of a “workhorse” for UHV STM applications where rapid ultimate resolution is required. The proven Omicron eddy current damping allows high-resolution STM even in non-ideal conditions. An easy-to-use, pincer-grip wobble stick is used for fast transfer action between the main system manipulator, the sample/tip storage carousel and the sample acceptor in the UHV STM 1. An in-vacuum I/V converter close to the tip provides lowest noise conditions. UHV System Integration The UHV STM 1 is housed in its own, dedicated UHV chamber, which can either be mounted onto a standard Omicron system (Multiprobe™…) or bolted onto to an existing vacuum system. This concept allows easy access to the microscope and avoids interference with other techniques. Omicron’s proven internal spring suspension system with eddy current damping ensures excellent vibration isolation. The bolt-on chamber houses a sample carousel for up to 8 samples/tips. Transfer of samples is quick and reliable using a wobble stick. Viewports on the bolt-on chamber allow optimal observation of the tip/sample coarse positioning using the external CCD camera.
