White Beam Mask

The white beam mask can be used in the front end or as a cost effeective alternative to the white beam synchrotron slit. The white beam mask consists of two Cu alloy blocks with tapered square cutouts that can be moved vertically and latteraly such that each of the blocks form one-half of the vertical and one-half of the horizontal beam definintion (like two L’s opposing eachother).

The standard max apperature is 23x23mm and the standard max heat absortion is 3000W. The resolution of the vertical and lateral motions are 1µm and the open loop reperability is < 3 um.
