Abstract
We developed a two-dimensional x-ray detector for x-ray beam profile analysis. The detector was built from commercially available parts, which included a low-cost 8-bit CCD camera, and a zoom lens coupled to a close-up lens, to which was attached a fiber-optic faceplate coated with (Gd2O2S:Tb) phosphor to a surface density of (10 mg/cm2). Testing of the detector unit has shown good linearity of response to the incident x-ray intensity (within ±4%), and good spatial linearity. The advantages of this detector lie mainly in its compactness, its ease of maneuverability, and the fact that it can be remotely controlled by a PC/AT computer at a reasonable cost (∼$1000 without the PC/AT).
