An experiment demonstrating the capability of a symmetrical layout type double crystal monochromator controlled using electronic cam technology

Abstract A demonstration test of a newly developed double crystal monochromator was performed on beamline BL06 in the NewSUBARU synchrotron radiation facility Hyogo University. Due to symmetrical layout 1st and 2nd units monochromator, maximum rotation speed main axis up 5.0 degrees/sec could be achieved. The is controlled by control board programmed with an electronic cam algorithm. system allows both Z 1 2 axes successively synchronized as Bragg angle changes. are moved apart equal amounts from center gravity increased. Also, at which increases larger angle. This can maintain stable exit beam height just well previous mechanical type monochromators proved measured encoder observed fluorescent screen. system, suitable for industrial use because it handle wide energy range high-throughput experiments carried out.
