Enye inxalenye yesixhobo sokufunxa (i-plasma ejongene nezinto ezijongene nayo) yesixhobo sokulinga ukudibanisa kunye ne-reactor yokudibanisa yexesha elizayo idibana neplasma.Xa i-plasma ion ingena kwizinto eziphathekayo, ezo ngqungquthela ziba yi-athomu engathathi hlangothi kwaye zihlala ngaphakathi kwezinto.Ukuba ibonwa kwii-athomu ezibumba izinto, ii-ion zeplasma ezingenileyo ziba zii-athomu zokungcola.Iiathom zokungcola zihamba kancinci kwizithuba phakathi kwee-athomu ezibumba izinto kwaye ekugqibeleni, zisasazeke ngaphakathi kwezinto.Kwelinye icala, ezinye iiathom ezingacocekanga zibuyela phezulu zize ziphinde ziphume kwiplasma.Ukuvalelwa okuzinzileyo kweplasma ye-fusion, ibhalansi phakathi kokungena kwee-ion ze-plasma kwizinto eziphathekayo kunye nokukhutshwa kwakhona kwee-athomu zokungcola emva kokufuduka ngaphakathi kwempahla kubaluleke kakhulu.
Indlela yokufuduka yee-athomu zokungcola ngaphakathi kwezixhobo ezinokwakheka kwekristale efanelekileyo icaciswe kakuhle kuphando oluninzi.Nangona kunjalo, izinto ezibonakalayo zinezakhiwo ze-polycrystalline, kwaye ke iindlela zokufuduka kwimimandla yemida yeenkozo zazingekacaciswa.Ukuqhubela phambili, kwizinto ezithinta ngokuqhubekayo i-plasma, isakhiwo se-crystal siphukile ngenxa yokungena ngokugqithiseleyo kwee-ion ze-plasma.Iindlela zokufuduka kwee-athomu zokungcola ngaphakathi kwezinto ezinokwakheka kwekristale ephazamisekileyo azizange zihlolwe ngokwaneleyo.
Iqela lophando likaNjingalwazi Atsushi Ito, wamaZiko eSizwe eNzululwazi yezeNdalo i-NIFS, liye laphumelela ekuphuhliseni indlela yokukhangela ngokuzenzekelayo nangokukhawuleza malunga neendlela zokufuduka kwizinto ezinejiyometri yeathom engalawulekiyo ngokusebenzisa amandla emolekyuli kunye nokubala okufanayo kwi-supercomputer.Okokuqala, bakhupha inani leendawo ezincinci ezigubungela yonke imathiriyeli.
Ngaphakathi kwendawo nganye encinci babala iindlela zokufuduka zeeathom zokungcola ngokusebenzisa i-molecular dynamics.Ezo zibalo zemimandla emincinci ziya kugqitywa ngexesha elifutshane kuba ubungakanani besizinda buncinci kwaye inani le-athomu ekufuneka liphathwe alininzi.Ngenxa yokuba izibalo kwi-domain nganye encinci ingenziwa ngokuzimeleyo, izibalo zenziwa ngokuhambelana nokusetyenziswa kwe-NIFS supercomputer, i-Plasma Simulator, kunye ne-HELIOS inkqubo ye-supercomputer kwi-Computational Simulation Centre ye-International Fusion Energy Research Centre (IFERC-CSC), i-Aomori, Japhan.KwiPlasma Simulator, kuba kunokwenzeka ukusebenzisa i-70,000 CPU cores, ukubala ngaxeshanye ngaphezulu kwe-70,000 yemimandla enokwenziwa.Ukudibanisa zonke iziphumo zokubala ezivela kwiinkalo ezincinci, iindlela zokufuduka phezu kwezinto zonke zifunyenwe.
Indlela enjalo yongqamaniso yekhompyuter ephezulu yohluka kuleyo isetyenziswa rhoqo, kwaye ibizwa ngokuba yiMPMD3) -uhlobo lokuhambelana.Kwi-NIFS, indlela yokulinganisa esebenzisa ngokufanelekileyo i-MPMD-type parallelization yayicetyiwe.Ngokudibanisa ulungelelwaniso kunye neengcamango zamva nje malunga nokwenziwa ngokuzenzekelayo, baye bafika kwindlela yokukhangela ngokuzenzekelayo kwisantya esiphezulu sendlela yokufuduka.
Ngokusebenzisa le ndlela, kuyenzeka ukuba ukhangele ngokulula indlela yokufuduka yee-athomu zokungcola kwizinto zokwenyani ezinemida yeenkozo zekristale okanye nezixhobo apho ubume bekristale buphazamiseka kukunxibelelana kwexesha elide neplasma.Ukuphonononga isimilo sokufuduka ngokudibeneyo kweeathom zokungcola ngaphakathi kwemathiriyeli esekwe kulwazi malunga nale ndlela yokufuduka, sinokulwenza nzulu ulwazi lwethu malunga nokulingana kwamasuntswana ngaphakathi kwiplasma kunye nezinto.Ngaloo ndlela ukuphuculwa kokuvalelwa kweplasma kulindelwe.
Ezi ziphumo zithiwe thaca ngoMeyi 2016 kwiNkomfa yaMazwe ngaMazwe ye-22 ye-Plasma Surface Interaction (PSI 22), kwaye iya kupapashwa kwijenali ye-Nuclear Materials and Energy.
