The AT-C8-HV slit was developed for scientists at the APS who needed to get a high precision slit into the immediate proximity of the sample, while still maintaining vacuum and visibility to several backscattering detectors.
The result is this extremely compact AT slit with centered opening.
The slit system holds four in-vacuum motors that set the position and the opening of the aperture. For each dimension, one motor defines the aperture opening and another determines the position of the aperture. Due to the fact that only one motor is moved during a one-dimensional scan, the AT-C8-HV is the optimum choice for high precision scans with a fixed aperture.
