Neutron and X-ray tomography at Necsa

نویسنده

چکیده

Neutrons are sourced from the SAFARI-1 nuclear research reactor operated by Necsa. Necsa is located at Pelindaba in the Northwest Province of South Africa, which is 30 km west of Pretoria. The South African Neutron Radiography (SANRAD) facility is located on the beam port floor of the SAFARI-1 nuclear research reactor hall and sources neutrons from beam port No. 2. The facility has neighbouring facilities, i.e. a small angle neutron scattering (SANS) facility (beam port No. 1) and a neutron diffraction (NDIFF) facility (beam port No. 5), as shown in Figure 1.

Forty Years of X-Ray Binaries

In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...

Assessment of X-Ray Crosstalk in a Computed Tomography Scanner with Small Detector Elements Using Monte Carlo Method

Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...

Neutron radiography and other NDE tests of main rotor helicopter blades.

A few nondestructive examination (NDE) techniques are extensively being used worldwide to investigate aircraft structures for all types of defects. The detection of corrosion and delaminations, which are believed to be the major initiators of defects leading to aircraft structural failures, are addressed by various NDE techniques. In a combined investigation by means of visual inspection, X-ray...

A COMPARISON BETWEEN THERMAL AND X RADIOGRAPHY FOR STUDYING THE INTERNAL STRUCTURE OF BIOLOGICAL

 ABSTRACT Background: With respect to the difference in the interaction of thermal neutron and X rays with matter, using two radiography systems of thermal neutron and X rays will yield highly valuable information for studying the inner structure of biologic samples. Methods: The high sensitivity of thermal neutron to hydrogen, in particular, has led to recognizing this system as a useful tool ...
