(a) The attenuator wheel assembly. The foils are held inside each of the inserts and the beam passes through the point where all three wheels intersect. (b) CIVIDEC XBPM mount. The four active pads used for monitoring beam intensity and position are coloured pink. (c) Sample shutter showing the stepped arrangement of the blades that allow for altering patterns of opening and closing. Blue is 50/50 and pink is 75/25. (d) Goniometer assembly showing the air-bearing, the scissor-like x–y translation stages, the z motion, the mirror interferometers and the tilt mechanism. |
