deuterium AND tritium - 2024 Chicago Open

Question

Two answers required. An ion beam of these two nuclear species, typically accelerated into a titanium target, serves as part of “compact neutron generators.” Research at the NBTF in Italy uses negative ions of one of these nuclear species in neutral-beam injectors that target a mixture of these two species. One of these two species is used in radioluminescent powerless (15[1])lighting systems, and is produced from the other of these species through neutron (*) capture as a byproduct (10[1])of CANDU (10[1])(“can-doo”) reactors. The 1991 PTE experiment at JET (“jet”) used an 11/89 mixture of these two species, although an optimal 50/50 mix is assumed in Lawson’s criterion. (-5[1])The rarer of these two species (10[1])is produced from lithium “breeding blankets” (-5[1])using neutrons produced from the fusion of these two species in designs like ITER (“EE-tur”). For 10 points, (10[1])what two species (10[1])used as fuel in modern tokamaks (10[1])are the isotopes (10[1])of hydrogen with one (10[1]-5[1])and two neutrons? (10[1])■END■ (10[2]0[1])

ANSWER: deuterium AND tritium [accept H-2 or hydrogen-2 or D in place of “deuterium”; accept H-3 or hydrogen-3 or T in place of “tritium”; accept D–T fusion; prompt on heavy water or D2O in place of “deuterium” by asking “what is the specific isotope?”; prompt on hydrogen in place of either “deuterium” or “tritium” by asking “what is the specific isotope?”]
