← ScienceWhich energy loss mechanism strongly influences fusion reactor efficiency?
A)Bremsstrahlung radiation emission✓
B)Neutron absorption by the coolant
C)Synchrotron radiation losses
D)Alpha particle confinement degradation
💡 Explanation
Bremsstrahlung radiation reduces fusion efficiency because accelerated electrons emit photons when scattered by ions; this process is radiative loss. Therefore, thermal energy is lost by radiation rather than sustaining the fusion, because fusion plasma interacts electromagnetically.
