The Rainwater Memorial Calibration Facility for X-Ray Optics
Figure 3
Facility overview with source room connected to calibration room by 162.2 m long tunnel pipe line and calibration room connected to detector room by 10 m detector pipe line. The individual components are (a) high power X-ray tube (b) thin four-film filter unit, and thick (up to 50 mm) attenuator. The filter unit is remote controlled, while the attenuator block must be inserted and removed manually. (c) Collimator plate with 12 mm aperture, (d) 22 mm diameter 75 μm thick Kapton vacuum window, (e) 48 cm diameter Kevlar-reinforced Mylar vacuum window, (f) coarse aperture plate, (g) autocollimator, (h) fine aperture plate, (i) calibration bench for mounting optic. Available movements are translation, roll, yaw, and pitch indicated by green arrows (j and k) 48 cm Kevlar-reinforced Mylar vacuum windows. (l) Four-blade slit unit. Each blade is 4 mm thick Tungsten. Maximum aperture size is mm2 and the entire unit can be translated and rotated in yaw (m) X-ray detector. Detector can be translated (n) Beam monitor. Beam monitor can be translated in both X and Y to facilitate unobstructed view during calibration.
