Adaptation kit for Beetle-type SPMs
Full software and manual control for any Beetle-type SPM head
The adaptation kit for beetle-type SPM heads (AKBE) offers full control for the operation of a Beetle-type SPM head. All coarse, scan and offset configurations are accessible through the Nanonis user interface and are, once configured, also available when using the PMD4 handset. A manually operated switchbox is no longer necessary.
The auxiliary channel of the HVA4 can easily be used to add Z-offsets. With a dual-HVA4 configuration, the scan reach can be significantly extended also in X-Y direction by applying offset voltages to the electrodes of the outer piezo tubes if the central tube is used for scanning.
The AKBE required a HVA4 and a PMD4b for operation.
Flexible configuration of the scan, coarse and offset modes
The motor control module for the AKBE offers individual options for the Z and X/Y electrodes of both the central piezo tube and the outer piezo tubes. It can be set for configurations where the outer tubes have piezo electrodes with a 0o/90o or 45o orientation with respect to the X/Y motion axes, and for cases where the center piezo has 5-, 4- 2-quadrant (z-only) configurations or where there is no center piezo at all.
- The X/Y electrodes of the outer piezos can be configured for coarse motion only or for combined coarse and scanning motion. The can also be connected to GND if no motion is required
- The Z electrodes of the outer piezos can be configured for Z-offset (AUX channel of the HVA4), Z-feedback or connected to GND
- The X/Y electrodes of the center piezo can be configured for scanning motion or connected to GND
- The Z electrode of the center piezo can be configured for Z-feedback, Z-offset (AUX channel of the HVA4) or connected to GND
