Bender of crystal 2 in the monochromator. Bottom: drawing of the bender showing its two independent pushing rhombs. Top: drawing of crystal 2 and crystal holder. (1) Thin silicon crystal with ribs on the back for preventing anticlastic curvature, firmly glued onto the holder; (2) U-shaped stainless-steel crystal holder which is curved, together with the crystal, by the bender which pushes aside the legs of the holder; (3) flexible part of the crystal holder allowing twist correction; (4) motorized jack acting on (3) for correcting the twist of the bent crystal. |
