A lokacin da na biyu da ake matsawa via radiation-induced ablation, neutrons daga primary kama sama da x-haskoki, shiga cikin na biyu, da kuma fara kiwo tritium via na uku dauki lura a cikin na farko sashe a sama. Wannan Li-6 + n dauki ne exothermic, samar da 5 MeV da spark taron. A filasha ba a riga an matsa, kuma ta haka ne, subcritical fission, don haka ya rage wani gagarumin sakamako ko neutrons. Idan na farko fashewa samar da wani in mun gwada opaque radiation gaba a cikin tashar filler, wanda abubuwa kamar wani jinkirin-motsi logjam zuwa jinkirta da nassi na radiant makamashi.
