Ingxenye eyodwa yomkhumbi we-vacuum (izinto ezibheke kwi-plasma) yethuluzi lokuhlola le-fusion kanye ne-fusion reactor yesikhathi esizayo ihlangana ne-plasma. Lapho ama-ion e-plasma engena entweni, lezo zinhlayiya ziba i-athomu engathathi hlangothi futhi zihlale ngaphakathi kwento. Uma kubonakala kuma-athomu ahlanganisa izinto, ama-ion e-plasma angenayo aba ama-athomu okungcola. Ama-athomu okungcola ahamba kancane ezikhaleni phakathi kwama-athomu ahlanganisa into futhi ekugcineni, asakazeke ngaphakathi kwento. Ngakolunye uhlangothi, amanye ama-athomu okungcola abuyela phezulu aphinde akhishelwe kuyi-plasma. Ngokuvalelwa okuzinzile kwe-fusion plasma, ibhalansi phakathi kokungena kwama-ion e-plasma kokubalulekile kanye nokuphuma kabusha kwama-athomu okungcola ngemva kokufuduka ngaphakathi kwento ebaluleka kakhulu.

Indlela yokufuduka kwama-athomu okungcola ngaphakathi kwezinto ezinokwakheka kwekristalu efanelekile icaciswe kahle ocwaningweni oluningi. Kodwa-ke, izinto zangempela zinezakhiwo ze-polycrystalline, bese izindlela zokufuduka ezifundeni zomngcele wokusanhlamvu bezingakacaciswa okwamanje. Ngaphezu kwalokho, ezintweni ezithinta i-plasma ngokuqhubekayo, isakhiwo sekristalu siphukile ngenxa yokungena ngokweqile kwama-ion e-plasma. Izindlela zokufuduka zama-athomu okungcola ngaphakathi kwento enesakhiwo sekristalu esiphazamisekile bezingakahlolwa ngokwanele.

Iqembu locwaningo likaSolwazi Atsushi Ito, weNational Institutes of Natural Sciences NIFS, liphumelele ukwenza indlela yokusesha okuzenzakalelayo nangokushesha mayelana nezindlela zokufuduka ezintweni ezinejiyomethri ye-athomu engafanele ngokusebenzisa amandla emolekyuli nokubala okufanayo kukhompuyutha enkulu. Okokuqala, bakhipha inqwaba yezizinda ezincane ezihlanganisa yonke into.

Ngaphakathi kwesizinda ngasinye esincane babala izindlela zokufuduka zama-athomu okungcola ngokusebenzisa amandla e-molecular. Lezo zibalo zezizinda ezincane zizoqedwa ngesikhathi esifushane ngoba usayizi wesizinda mncane futhi inani lama-athomu okufanele aphathwe aliningi. Ngenxa yokuthi izibalo kusizinda ngasinye esincane zingenziwa ngokuzimela, izibalo zenziwa ngokuhambisana kusetshenziswa i-supercomputer ye-NIFS, i-Plasma Simulator, kanye nohlelo lwamakhompiyutha amakhulu lwe-HELIOS e-Computational Simulation Center of International Fusion Energy Research Center (IFERC-CSC), i-Aomori, Japan. Ku-Plasma Simulator, ngoba kungenzeka ukusebenzisa ama-CPU angu-70,000 cores, izibalo ngasikhathi sinye ezingaphezu kwezizinda ezingama-70,000 zingenziwa. Ukuhlanganisa yonke imiphumela yokubala evela ezizindeni ezincane, izindlela zokufuduka phezu kwayo yonke into ziyatholwa.

Indlela enjalo yokufanisa ye-super computer ihlukile kuleyo evame ukusetshenziswa, futhi ibizwa nge-MPMD3) -uhlobo lokufana. Kwa-NIFS, indlela yokulingisa esebenzisa ngempumelelo ukufana kohlobo lwe-MPMD yayiphakanyiswe. Ngokuhlanganisa ukufana nemibono yakamuva emayelana nokwenza ngokuzenzakalela, bafike endleleni yokusesha esheshayo yesivinini esikhulu yomzila wokufuduka.

Ngokusebenzisa le ndlela, kuba nokwenzeka ukucinga kalula indlela yokufuduka kwama-athomu okungcola ukuze uthole izinto zangempela ezinemingcele yezinhlamvu eziyikristalu noma ngisho nezinto lapho ukwakheka kwekristalu kuphazamiseka ngokuthintana isikhathi eside ne-plasma. Ukuphenya ukuziphatha kokuhamba okuhlangene kwama-athomu okungcola ngaphakathi kwento esekelwe olwazini olumayelana nale ndlela yokufuduka, singajulisa ulwazi lwethu mayelana nebhalansi yezinhlayiyana ngaphakathi kwe-plasma kanye nokokusebenza. Ngakho-ke ukuthuthukiswa kokuvalelwa kwe-plasma kulindeleke.

Le miphumela yethulwa ngoMeyi 2016 eNgqungqutheleni Yamazwe Ngamazwe Ye-22 Ye-Plasma Surface Interaction (PSI 22), futhi izoshicilelwa kujenali I-Nuclear Materials and Energy.
