Which mechanism hinders sustained fusion when using deuterium isotopes?

💡 Explanation

Bremsstrahlung losses increase significantly with higher plasma temperatures in DT fusion; radiative losses dissipate more energy than alpha particle heating can replace because bremsstrahlung radiation scales with the square root of temperature, therefore leading to quenching of the fusion reaction rather than a sustained burn.
