Precision gearboxes can rotate the sample continuously during deposition, ablation or for other growth processing requirements. All goniometer and precision gearboxes are suitable for UHV use. Optional heating , cooling and sample transfer are available for most units. Please consult the factory for your application cost. The precision polar rotation, azimuthal rotation and flip motions move the sample about the virtual axis of the sample plane without line of sight interference.
Virtual axis allows glancing angle studies without gearbox shadow.
The TGB is a target gearbox only. To be a complete target drive system it must be connected to two rotary feedthroughs, one for the target rotation and the second used for clocking the targets into position to face the laser from behind the protective shroud. This capability can be used to sweep the ablated plume across the substrate. Last updated July 17, 1998.
