Figure 3
(a) An exploded view showing the individual components. The scintillator screen is housed in the threaded tube (4) and fixed in position using the clamp and spring (1, 2). The threaded tube (4) is then mounted into the front casing (6) and locked in position. By rotating (4), the distance of the scintillator relative to the casing and lens could be adjusted and locked. The aspheric lens is clamped between two metal rings and pushed towards the front casing by a spring (6, 7). The rear casing (10) holds the system together under stress. The alignment set screws (11) allow the adjustment of the lens angle and position relative to the scintillator screen. Panels (b) and (c) show photographs of the assembled system with a ruler for reference. |
