← ScienceWhich energy transformation limits pulsed fusion reactor efficiency?
A)Neutron moderation heats surrounding materials
B)Alpha particle escapes confine plasma
C)Bremsstrahlung causes radiative energy loss✓
D)Gamma ray emission causes direct ionization
💡 Explanation
Bremsstrahlung radiation converts particle kinetic energy to photons, because rapid deceleration of plasma ions causes radiative energy loss. Therefore option C, rather than the other options, occurs significantly at high fusion temperatures because lighter electrons undergo greater acceleration.
