Mechanical module of Solver-P7UHV

Vibration isolation is provided by three springs that suspend the microscope module that is connected with the carrying flange by a bellows connection. Oscillations are damped by CoSm magnetic eddy current damping.

The sample-to-probe approach is achieved by a vacuum compatible stepper motor with a planetary reduction gear. Use of this reduction gear eliminates jamming during process of ultra-high vacuum.

Two vacuum chambers design:

High Vacuum chamber:
- Windows for samples observing;
- Manipulators allow to load and move samples, renewal of cantilevers and STM tips wihout depressurization;
- Additional flanges;
- Ultra-high vacuum (UHV) greater than 10^-10 torr is achieved by utilization of cryo-adsorption, ion, and sublimation titanium pumps.

Low vacuum chamber:
- Low-vacuum chamber with removable optical position system of cantilever position registration.

Solver P7 Controller Electronics:

Advanced electronics High-Q - 22 bits resolution in X, Y, allows to set frequency with ultimate 0.01 Hz, which allows to use probes with highest Q-factor with band <1Hz (cantilevers in vacuum).
