The MP1 XRF mounting plate was designed to facilitate the use of the XR100/X-123 and Mini-X x-ray tube. The plate provides a standard 45 degree detector to x-ray tube XRF geometry. Mounting holes for both the XR100 and X-123 are provided. The moutning holes for the x-ray tube are only for use with the Mini-X.

Figure 3. MP1 mounting plate mechanical dimensions. The distance from the edge of the plate to the sample should be 0.375 inches (1 cm) in order to be at the intersecting point of the detector and x-ray tube. All dimensions are in inches (in).

Figure 4. MP1 mounting plate height dimensions. Height dimensions are from the top of the plate. All dimensions are in inches (in).

Figure 5. MP1 45 degree detector to tube XRF angles and distances. The distance from the edge of the plate to the sample should be 0.375 inches (1 cm) in order to be at the intersecting point of the detector and x-ray tube. All dimensions are in centimeters (cm).
