SUMMARY
The D-D reaction is chosen for the Divertor Tokamak Test Facility (DTT) in Frascati, Italy, due to its smaller cross section compared to the D-T reaction and the lower energy of emitted neutrons. This selection significantly impacts heat and particle exhaust management in the divertor, which primarily experiences ion bombardment from the plasma. The DTT is designed as a divertor test facility and will not engage in significant fusion reactions, making deuterium a more manageable option than tritium.
PREREQUISITES
- Understanding of fusion reactions, specifically D-D and D-T reactions.
- Knowledge of plasma physics and its interaction with divertors.
- Familiarity with heat and particle exhaust systems in tokamak designs.
- Basic principles of neutron behavior in fusion environments.
NEXT STEPS
- Research the impact of neutron energy on divertor materials in fusion reactors.
- Explore the design and operational principles of divertor test facilities.
- Study the differences between D-D and D-T fusion reactions in detail.
- Investigate the challenges of tritium handling in fusion environments.
USEFUL FOR
Researchers, engineers, and physicists involved in fusion energy development, particularly those focusing on tokamak design and divertor technology.
