Microscope Setup
The sample is mounted onto a stack consisting of an ANPxyz101 coarse
positioning unit, an ANSxyz100 scanner and a copper sample plate that
carries heater and temperature sensor. The attoAFM I module, consisting
of the cantilever holder and the attoAFM I head together with the fiber
based deflection detection system, is fixed onto a slide which is mounted
in the microscope housing.
The microscope module is mounted below the 3He pot . The top of the 3He
insert contains all electrical connectors and feedthroughs, the vacuum
window, and the fiber feedthrough. The AFM module including the fiber-
and sample positioning units is attached to the bottom of the insert, see
Figure 5. The microscope housing is inserted into a inner vacuum chamber
(IVC) and subsequently sled into the cryostat utilizing a log G10 tube .

The positioning stage ANPxyz101 is built from three individual positioners
mounted on top of each other (please find the specifications in the
respective manual). The ANSxyz100 scanners will be mounted on top of the
positioner stack, followed by a plate with integrated heater and
