The slits will be used at front end of Diamond I13 X-ray Imaging and Coherence beamline which has two canted beamline branches. Required by the beamline optics, the front end slits function as virtual sources for the 250 meters long beamline. Working for the dual beam geometry, these specialised slits can vary the size of one x-ray beam with rotational motions while allowing the second beam to pass through unaffected. The rotational operations of the slits are achieved by an innovative commercial flex pivot and a unique in-house designed pivoting flexure.
