Abstract
Measurement and analysis of the energy distribution of the neutron emission from the nuclear burnup of tritons produced at 1 MeV in d+d --> t+p reacti ons are reported. The results refer to deuterium plasmas with a strongly pu lsed neutron production attained with neutral beam heating in the JET tokam ak representing both quasi-steady and transient plasma conditions. The meas ured triton produced neutron spectrum is described with reference to the tr iton slowing down behaviour in the plasma and pertinent parameter dependenc es as predicted with a time dependent model. The first study of the triton burnup neutron spectrum for both transient and quasi-steady-state plasma co nditions is presented and a description based on classical confinement and slowing down of fast tritons is largely supported.
