PPPL - National Spherical Torus Experiment (NSTX)
A ride around toy train tracks inside a fusion experimental
machine can reveal much about a hot gas called plasma.
PPPL research staff recently mounted a neutron source on
a toy train inside the National Spherical Torus Experiment
(NSTX), placed it on hobby train tracks that had been
installed and sent it on a three-day continuous zip around
the rails. The purpose: to calibrate the neutron rate
during fusion experiments.
