Comparative modelling of X-ray backscattering in the Novillo tokamak

摘要

Results of X-ray backscattering studies on the Novillo tokamak using thermoluminescent dosimeters (TLDs) are presented. Dose measurements were carried out on the equatorial plane of the tokamak along 12 radial directions. The backscattering can be due to the interaction of the radiation with the surrounding walls. Two kinds of phenomenological mathematical methods describing the X-ray backscattering were obtained from the experimental data and compared. Good agreement was found between the data and the predictions of the models. (C) 2001 Published by Elsevier Science Ltd. [References: 10]
