Abstract

Experimental data of neutron yield Y n against pinch current I pinch is assembled to produce a more global scaling law than available. From the data a mid-range point is obtained to calibrate the neutron production mechanism of the Lee Model code. This code is then used for numerical experiments on a range of focus devices to derive neutron scaling laws. The results are the following: Y n = 2 × 1011 I pinch 4.7 and Y n = 9 × 109 I peak 3.9. It is felt that the scaling law with respect to I pinch is rigorously obtained by these numerical experiments when compared with that obtained from measured data, which suffers from inadequacies in the measurements of I pinch.
