Abstract
Bremsstrahlung is one of the most important energy loss mechanisms in
achieving ignition, which is only possible above a threshold in
temperature for a given fusion reaction and plasma conditions. A
detailed analysis of the bremsstrahlung process in degenerate plasma
points out that radiation energy loss is much smaller than the value
given by the classical formulation. This fact seems not useful to relax
ignition requirements in self-ignited targets, because it is only
relevant at extremely high densities. On the contrary, it can be very
positive in the fast ignition scheme, where the target is compressed to
very high densities at a minimum temperature, before the igniting
beamlet is sent in.
