Abstract

A new collimator of 0.3 × 2 mm aperture and a beam trap have been made for the Philips 114.83 mm camera. As a result of this, longer spacings cart be recorded (d=35 Å with Co Kα, with scope for further improvement by slimming the beam trap) the resolution of the camera has been improved, the background scatter is considerably reduced, and the exposure time is reduced by about one-third, in comparison with the standard collimator of 1 mm diameter.
