O LE FAIGOFIE Faʻaogaina o SMALL Neutron III

I le neutron imaging, le neutron tatau ona lemu lemu i lalo i le saoasaoa manaʻomia mo le ata pe a uma ona gaosia. O le saoasaoa o neutrons aafia ai le loloto o le ofi ma le mulimuli ata, faʻatagaina lelei-faʻaleleiina o le gaioiga. asiasiga o uelo, lafoina vaega, laupepa laupepa, uʻamea faʻatosina uʻamea ma maualuga-le sao vaega i alamanuia ma isi fanua, i le mauaina o mea pāpā.

Neutron activation analysis (NAA) e eseʻese mai neutron imaging ma masani ona galue i le tutusa auala e pei o Curiosity's DAN module. O le faʻateleina o le faʻaaogaina o fusion-faʻavae neutron gaosi mo neutron imaging ma fesoʻotaʻi mafuaʻaga mafai ai mo laiti, sili lelei masini e tulaʻi mai. O le US military's NEMESIS (neutron emission mobile explosives sensing and recognition system) polokalama o se tasi o ia polokalame, ina ia faʻafaigofie ai le faʻaaogaina o tamaʻi masini, e mafai ona maitauina le masini faʻapapa (IED) faʻapea ma maina o mea pāpā, ma e oʻo lava i le uʻamea ma le eleele sulu radar (GPR) e iloa saoloto o maina uʻamea.

Phoenix LLC, o loʻo aʻafia i le poloketi NEMESIS, talitonu o le NAA ma neutron imaging mea faigaluega e mafai ona faʻaaogaina i le lumanaʻi le gata mo galuega matautia, ae faʻapea foi mo galuega masani e pei o le siakiina o alalaupapa ma asiasiga vaʻalele. E tusa ai ma le kamupani, tele o le taumafaiga ua taulaʻi nei i le faʻaleleia atili o le mauaina o algorithms ma faia masini sili atu le malosi ma gafatia.

Mea faatusa
E ui o le tele o nei mea e foliga manaia, pei o le mafai ona 'vaʻai' i totonu o le eleele, mauaina ni mea pāpā na tanu, pe vaʻai i taʻetaʻei i laupepa poʻo le soʻoga faʻamau, e mafai e se tasi ona vaʻai i ai o se muamua i luga o masani masani ona faʻaaogaina metotia pei o X-ray . Talu mai le seneturi lona 20, ua maua le X-ray ma isi radiation e faigofie ona gaosia, ae o le gaioiga o le faʻatupuina o le tele o neutrons i se auala lelei e aunoa ma le manaʻomia o se malosiaga o le malosiaga o le eletise na faʻaleleia atili mo le tele o tausaga.

Fusion masini e tele ona lelei ma e le faigata ona faʻataʻitaʻi. Mo se fale e le faʻamaufaʻailogaina, o le faʻaauau pea o sapalai o le deuterium-tritium (poʻo le deuterium-deuterium) suauu e le manaʻomia se tausiga, seʻi vagana ai le suia o vaega e gaosia ai leisa. O nei vaega e faatatau i le maualalo - ma le feololo laʻasaga faʻataʻavaleina otaota, lea e tutusa ma otaota gaosia i falesuesue ma falemaʻi ma e faigofie ona lafoai.

E ui lava o ni masini e tilotilo ai i lima e faʻaaoga ai mea neutron mo suʻesuʻega o le siʻosiʻomaga o loʻo fai lava sina mamao ese atu, o ata faʻataʻitaʻi o le neutron e i ai le avanoa e faʻaleleia atili ai olaga i le tele o auala, pei lava o X-ray faia.

O faʻatekinolosi faʻafitauli e tatau ona foia i le faʻaogaina o le faʻaaogaina o le radiation puipuia i le malosiʻaga faaniukilia :(1) Faʻafefea ona mamanuina 8% boron-o loʻo iai le polyethylene laupapa; (2) Faʻafefea ona faia boric acid ma polyethylene liusuavai i le tutusa vevela i le gaioiga, ae le o le fausiaina metaboric acid ma pyroboric acid, ina ia faigofie ai ona palu, vevela, extrusion ma roll fausia. 1. E tusa ai ma le vailaʻau faʻavae H3BO3 ma atomic mamafa o boric acid, o le pasene o boron ua fuafuaina e avea ma 17.48%, ma o le mamafa pasene o boric acid e tatau ona faʻaopopoina i le 100 kg boron-o aofia ai polyethylene ua fuafuaina e avea ma 46% , ma le 8% boron-o loʻo iai le laupapa polyethylene ua fuafuaina. 2, o le atinaʻeina o le boric acid gaosi vevela mafai ona siʻi le tumau i le 120 ℃ aunoa ma le pala o le A solvable sooupu, ae mafai foi faʻaititia le liusuavai vaega o maualuga density polyethylene i 120 ℃ B solvable sooupu, e foʻia ai le faʻafitauli o boric acid coking. Talosaga: puipuiga o le neutron radiation i nofoaga o malosiaga faaniukilia, feololo (maualuga) televave o malosiaga, atomic reactors, submarines faaniukilia, vailaau faavavevave, neutron togafitiga masini ma isi nofoaga.

O la matou kamupani faʻapitoa i le gaosia o borated polyethylene sheet, lead boron polyethylene sheet ma isi oloa. E mafai ona matou faia le faʻagaioiga o le CNC e tusa ma ata. O le boron mea eseese e fesuisuiaʻi foliga 2% i le 50%. Afio mai e faʻafesoʻotaʻi matou!
