The MULTIPROBE LT UHV systems are dedicated surface science systems for the low temperature UHV STM. Three standard MULTIPROBE LT configurations are available – S, XP and XA.

Each standard system can be used as a base to match the customer’s special requirements. The LT S represents the basic system configuration with the LT STM main chamber and an easy to operate fast entry chamber. Transferring samples and probe tips is made quick and reliable using a UHV wobble stick.

Omicron UHV systems are optimized for high throughput, reliable and secure operations. The wobble stick based transfer in the LT STM microscope enables for fast sample exchange (< 30 s) with the sample either cooled or at room temperature.

The LT XP system is an extended version of the LT S offering a separate chamber for various sample preparation and analysis techniques. These could include sample heating, sputter cleaning, evaporation/deposition and analysis techniques such as LEED and RHEED.

The LT XA system provides an extended sample preparation/analysis chamber for a variety of surface analysis techniques such as XPS, UPS, ISS, LEED, AES or others. The MULTIPROBE LT XA can also be equipped with a cold sample transfer to keep the sample well below 50 K during all UHV operations.

Omicron´s key strength is the capability to combine a wide range of techniques in one instrument - the multi-technique approach. Following this philosophy, the LT STM has been integrated into customized system solutions with research emphasis ranging from magnetism, electron spectroscopy to MBE and many others.

The modularity of the MULTIPROBE LT STM fits perfectly with the wide range of other modular solutions Omicron offers. Omicron has the unique flexibility, expertise and infrastructure to develop completely new system concepts to meet nearly every customer’s special requirements. Each system is designed to guarantee true UHV operation in the 10^-11 mbar range and ease-of-use with secure operation, while retaining the LT STM’s high level of performance and versatility.
