The systems consist of two chambers:

1. The preparation chamber
A sample introduction system
Typical surface preparation equipments (sputtering and annealing)
Characterization apparatuses (LEED, AES and RGA)

2. The microscope chamber
An on top He and nitrogen crypostat
A wobble stick for in-situ sample and tip transfer
Gas introducers for in-situ LT adsorption experiments

The microscope is designed so that high spatial resolution and low noise are achieved.

High mechanical stability obtained by pnuematic damping of the UHV system as well as springs and eddy cyrrent damping of the microscope body

Low drift rate, which is minimized by the choice of amterials with similar thermal expantion coefficients (Macor and Ti) and a symmetric design

Proper shielding of the electric wires, by twisting them when necessary and pasing them through the cryostat separated in proper groups that are shielded from each other by metallic pipes
