ACCELERATOR BEAM LINES IN RESEARCH AND DEVELOPMENT AT NECSA

 

 

Presented by

 

MR GRAHAM DANIELS

 

From

NECSA (South African Nuclear Energy Corporation Limited)

 

 

ABSTRACT:

 

P-Labs at Necsa consist of two linear particle accelerator facilities; a Van de Graaff with        terminal potential up to 4 MV and two radio frequency quadrapole (RFQ) accelerator s          ystems that can accelerate D+ ions to 3.7 – 5.1 MeV (or protons to 1.8 – 2.5 MeV).              Depending on the beam target used these accelerators can produce fast neutrons (and          associated gamma rays) at a rate of 106- 1012 n/cm2/s.

 

One can utilize the high penetrative nature of the fast neutrons as well its ability to   distinguish between different elements, to conduct radiography and tomography on           samples.  These fast neutrons can also be used to conduct time of flight analysis.  One can             also utilize the associated gamma rays together with the fast neutrons for material    identification and non destructive testing including identification of threat material within       cargo.  Utilization of the Monte Carlo Neutral Particle code (MCNP) is also done to             simulate the facility and experiments beforehand.  Some of the techniques currently   being investigated will be presented here.
