R. Wojcik et al., DEVELOPMENT OF X-RAY MINI-PROBES FOR THE DIGIRAY RGX SYSTEM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 353(1-3), 1994, pp. 307-311
We have developed and tested a variety of X-ray mini-probes for the Re
verse Geometry X-radiography((R),1) (RGX) system each having their own
advantages and disadvantages. These mini-probes consist of small scin
tillators (as small as 2 mm in diameter and 5 mm long) attached to opt
ical light guides (as long as 14 m) coupled to photomultipliers. Image
s produced with these probes show that even smaller probes and/or long
er light guides may be fashioned. Such probes may be useful in both no
n-destructive evaluation and medical imaging.
