The AIM series devices provide an easy interface for a wide range of
sample approach and positioning systems. The AIM modules provide
automated approach and computer-controlled coarse position control when
combined with the RHK SPM 1000.
RHK has developed AIM modules for Omicron's® MicroSlide control,
Physical Electronics'® Servo motor control, and stepper motor systems
such as Molecular Imaging's® PicoSPM, Digital Instruments'® Multimode™,
Nanoscope™, and Dimension™ microscopes, and for JEOL® UHV scanning probe
microscopes.
AIM series models are: AIM-Omicron, AIM-MI, AIM-JEOL, and AIM-TTL. |

The Model PPC-100 provides switchable approach and X, Y, Z coarse
position control with multi-tube scan heads, such as the “Besocke –
Beetle” design, which is the standard RHK scan head for STM and AFM.
The PPC-100 works by routing high voltage sawtooth waveforms to one or
more of the outer piezo tube sectors, depending on the desired axis of
motion.
The PPC-100 comes standard with RHK's UHV SPM subsystems and complete
systems. |

Position control and nanoscale motion of system components in scanning probe instruments often requires the use of highly specialized inertial piezo motors. These motors require a very sudden change in voltage to overcome strong frictional holding forces between the piezo and the secondary component. This requires special high voltage amplifiers with very fast slew rates. The RHK PMC 100 Piezo Motor Controller is designed to provide such a signal and can be directed to nine different outputs to operate nine separate motors! |

| The low voltage shape of the waveform output (before the high gain amplification stage) is shown in the diagram to the left. The slow rise segment (A) expands the piezo element, then the rapid drop (B) contracts the piezo suddenly, overcoming the static friction between it and the moving component. Speed of inertial motion is controlled by varying the time between sweeps or the period. |
