Hoʻokahi ʻāpana o ka moku ʻūhā (ka mea e kū pono ana i ka plasma) o ka mea hoʻokolohua fusion a me ka reactor fusion e hiki mai ana e hui pū me ka plasma.Ke komo nā ion plasma i loko o ka mea, ua lilo kēlā mau ʻāpana i ʻātoma kū ʻole a noho i loko o ka mea.Inā ʻike ʻia mai nā ʻātoma i haku i ka mea, ua lilo nā ion plasma i komo i mau ʻātoma haumia.Ke neʻe mālie nei nā ʻātoma haumia i waena o nā ʻātoma i haku i ka mea a ma hope, hoʻolaha lākou i loko o ka mea.Ma ka ʻaoʻao ʻē aʻe, hoʻi kekahi mau ʻātoma haumia i ka ʻili a hoʻokuʻu hou ʻia i ka plasma.No ka hoʻopaʻa paʻa ʻana o ka plasma fusion, ʻo ke koena ma waena o ke komo ʻana o nā ion plasma i loko o ka mea a me ka hoʻokuʻu hou ʻana o nā ʻātoma haumia ma hope o ka neʻe ʻana mai loko mai o ka mea i lilo i mea nui loa.

Ua wehewehe maikaʻi ʻia ke ala neʻe o nā ʻātoma haumia i loko o nā mea me ka hoʻolālā aniani maikaʻi i nā noiʻi he nui.Eia nō naʻe, loaʻa i nā mea maoli nā hale polycrystalline, a laila ʻaʻole i wehewehe ʻia nā ala neʻe i nā palena ʻāina.Eia kekahi, i loko o kahi mea e hoʻopā mau ana i ka plasma, ua wāwahi ʻia ke ʻano aniani ma muli o ka hoʻonui nui ʻana o nā ion plasma.ʻAʻole lawa ka nānā ʻia ʻana o nā ala neʻe o nā ʻātoma haumia i loko o kahi mea me kahi ʻano aniani ʻino.

Ua lanakila ka pūʻulu noiʻi o Polofesa Atsushi Ito, o National Institutes of Natural Sciences NIFS, i ka hoʻomohala ʻana i ke ʻano no ka huli ʻakomi a me ka wikiwiki e pili ana i nā ala neʻe i nā mea i loaʻa i ka geometry atom arbitrary ma o ka molecular dynamics a me nā helu like ʻana i kahi supercomputer.ʻO ka mea mua, lawe lākou i nā helu liʻiliʻi liʻiliʻi e uhi ana i nā mea āpau.

Ma loko o kēlā me kēia wahi liʻiliʻi e helu lākou i nā ala neʻe o nā ʻātoma haumia ma o ka molecular dynamics.E hoʻopau ʻia kēlā helu ʻana o nā kikowaena liʻiliʻi i ka manawa pōkole no ka mea liʻiliʻi ka nui o ka domain a ʻaʻole nui ka helu o nā ʻātoma e mālama ʻia.No ka mea hiki ke hoʻokele kūʻokoʻa ka helu ʻana i kēlā me kēia wahi liʻiliʻi, hana ʻia nā helu ʻana me ka hoʻohana ʻana i ka supercomputer NIFS, ka Plasma Simulator, a me ka ʻōnaehana supercomputer HELIOS ma ka Computational Simulation Center o International Fusion Energy Research Center (IFERC-CSC), Aomori, Iapana.Ma ka Plasma Simulator, no ka mea hiki ke hoʻohana i nā cores CPU 70,000, hiki ke hana ʻia nā helu like ʻana ma luna o 70,000 mau kikowaena.I ka hui ʻana i nā hualoaʻa helu a pau mai nā kāʻei kua liʻiliʻi, loaʻa nā ala neʻe ma luna o nā mea āpau.

He ʻokoʻa kēlā ʻano hana like o ka lolouila super mai ka mea i hoʻohana pinepine ʻia, a ua kapa ʻia ʻo MPMD3) -type parallelization.Ma NIFS, ua noi ʻia kahi ʻano simulation e hoʻohana pono ana i ka hoʻohālikelike ʻano MPMD.Ma ka hoʻohui ʻana i ka parallelization me nā manaʻo hou e pili ana i ka automatization, ua hōʻea lākou i kahi ala huli ʻakomi kiʻekiʻe no ke ala neʻe.

Ma ka hoʻohana ʻana i kēia ʻano, hiki ke ʻimi maʻalahi i ke ala neʻe o nā ʻātoma haumia no nā mea maoli i loaʻa nā palena o ka palaoa aniani a i ʻole nā ​​​​mea i hoʻopilikia ʻia ke ʻano kristal e ka pilina lōʻihi me ka plasma.Ke noiʻi nei i ke ʻano o ka neʻe ʻana o nā ʻātoma haumia i loko o nā mea e pili ana i ka ʻike e pili ana i kēia ala neʻe, hiki iā mākou ke hoʻonui i ko mākou ʻike e pili ana i ke koena o nā mea i loko o ka plasma a me nā mea.No laila ke manaʻo ʻia nei ka hoʻomaikaʻi ʻana i ka hoʻopaʻa plasma.

Ua hōʻike ʻia kēia mau hopena ma Mei 2016 ma ka 22nd International Conference on Plasma Surface Interaction (PSI 22), a e paʻi ʻia ma ka puke pai Nuclear Materials and Energy.
