Abstract

Empirical scaling relations are deduced describing the neutron emission from TFTR supershots using a database that includes all of the supershot plasmas (525) from the 1990 campaign. A physics based scaling for the neutron emission is derived from the dependence of the central plasma parameters on the machine settings and the energy confinement time. This scaling has been used to project the fusion rate for equivalent DT plasmas in TFTR, and to explore the machine operation space that optimizes the fusion rate. Increases in neutron emission are possible by either increasing the toroidal magnetic field or further improving the limiter conditioning.
