INFLUENCE OF NEUTRON SCATTERING AND SOURCE EXTENT ON THE MEASUREMENT OF NEUTRON ENERGY SPECTRA AT ASDEX
We consider the problem of nuclear emulsion measurements at ASDEX. Besides the application of the VINIA-3DAMC software, this needs a description of the plasma neutron source, a model of the ASDEX structure, and calculation of the response of the nuclear emulsion to the incoming spectral neutron flux. The latter is essential for comparing the numerical results with measurements at ASDEX. To treat this part, we developed the NEPMC software. The aim of the present work is not to give a detailed solution to all problems involved, but to demonstrate the feasibility, reliability and usefulness of the method. We therefore used simplified treatments for the ASDEX model, the plasma neutron source and the track statistics in the NEPMC software, which are now to be improved. It should be pointed out, however, that such calculations are of interest not only for nuclear emulsion measurements as well as any other neutron diagnostics, but also for all problems of neutron shielding for other diagnostics.
