The JJ X-Ray AT-C30-HV slit was developed for applications where relatively large apertures (up to 30 mm x 30 mm), and/or highly accurate slit-scans are required. The AT-C30 is therefore an optimum solution for customers with a need for blade motions similar to those of the standard AT-F7-HV slit, who have found the 7 mm opening too small.
The slit system holds four 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-C30-HV is the optimum choice for high precision scans with a fixed and relatively large aperture.
The blades can be installed in two configurations, either providing a curved surface of radius 16 mm or providing a knife-edge sloping at 0.5 degrees. Standard blades are polished to obtain a roughness better than 25 nm RMS.
In its basic configuration, the AT-C30-HV slit is delivered with a flange-opening and tightening bolts to allow connection with KF-40 flanges.
