Abstract
The dynamics and thermonuclear fusion parameters of a spinning
gas-puff staged
pinch are investigated by considering a DT-fibre plasma seeded with a Kr
impurity.
The effects of anomalous heating, line radiations from Kr, α-heating
and radiative
collapse are studied for different spin velocities Ω
0
,
keeping the spin coupling
parameter
f
0
(=0.1) fixed. Numerical
results indicate that the choice of Ω
0
is highly
critical. Large values of the spin velocities although provide stabilization
against
the R–T instability in the final stage of compression, but causes
an adverse reduction
in the values of the plasma parameters that are essential to achieve controlled
fusion. Our analysis suggests that a judicious choice of spin velocity
can provide
the desired temperature and density when we seed a DT-fibre plasma with
a small
fraction of Kr impurity to initiate radiative collapse.
