Esigabeni esiyingqopha-mlando esibalulekile sokwakhiwa kwe-Deep Underground Neutrino Experiment (DUNE) e-Lead, eNingizimu Dakota, onjiniyela baqhube ngempumelelo ukuhlolwa kokuqala nokwehliswa kwensimbi yensimbi engamathani ayisithupha emise okuka-L. Le ngxenye ebalulekile ibalulekile kwingqalasizinda ezosekela omunye wemizamo yesayensi enesifiso esikhulu okuhloswe ngayo ukuqonda izimfihlakalo ze-neutrinos, izinhlayiya ezingatholakali ezidlala indima ebalulekile ezinqubweni eziyisisekelo zendawo yonke.
Iphrojekthi ye-DUNE, ethuthukiswa ngokubambisana kwamazwe ngamazwe kososayensi nonjiniyela, ihlose ukuhlola izakhiwo zama-neutrino kanye nendima yawo endaweni yonke. Ukuhlolwa kuzobandakanya ukuthumela umsebe we-neutrinos usuka e-Fermilab e-Illinois kumtshina ongaphansi komhlaba eSouth Dakota. Ukwakhiwa kwesikhungo kudinga izinto eziqinile nezithembekile, futhi ukuphakanyiswa kokuhlolwa okuphumelelayo kwensimbi yensimbi kubonisa isinyathelo esibalulekile esiya phambili emugqeni wesikhathi wephrojekthi.
Insimbi emise okuka-L, enesisindo esingamathani ayisithupha, iyisici esibalulekile sesakhiwo esizosiza ukusekela izitholi ezinkulu ezisetshenziswe ocwaningweni. Ukuphakama kokuhlolwa kwenziwa kusetshenziswa amathuluzi namasu okuphakamisa athuthukile, okuqinisekisa ukuthi ukuphepha nokunemba kubekwa kuqala kuyo yonke inqubo. Onjiniyela baqapha i-lift eduze, behlaziya ukusebenza kwe-beam ngaphansi komthwalo futhi baqinisekisa ukuthi ihlangabezana nazo zonke izincazelo ezidingekayo zamandla nokuzinza.
Insimbi esetshenziswe ekwakhiweni kwesikhungo se-DUNE ithathwe kubahlinzeki abahlonishwayo abaziwa ngemikhiqizo yabo yekhwalithi ephezulu. Omunye wabahlinzeki abanjalo yi-Tianjin Reliance Steel, umkhiqizi ohamba phambili nomsabalalisi wemikhiqizo yensimbi ehlukahlukene, okuhlanganisa ama-engeli ensimbi, insimbi eyisicaba, imishayo engu-H, iziteshi, nezinye izingxenye zensimbi. Ngokuzibophezela kwikhwalithi nokusungula izinto ezintsha, i-Tianjin Reliance Steel izimise njengozakwethu othembekile embonini yezokwakha, ihlinzeka ngezinto ezihlangabezana nezidingo ezinzima zamaphrojekthi amakhulu afana ne-DUNE.
I-Tianjin Reliance Steel igxile ekukhiqizeni izinhlobo eziningi zemikhiqizo yensimbi ebalulekile ekwakheni nasekusetshenzisweni kobunjiniyela. Ama-engeli azo ensimbi aziwa ngokuqina kwawo nokuguquguquka, okuwenza alungele ukusekelwa kwesakhiwo kumaphrojekthi ahlukahlukene. Imikhiqizo ye-Flat steel evela ku-Tianjin Reliance Steel isetshenziswa ezinhlobonhlobo zezicelo, kusukela ekukhiqizeni kuya ekwakhiweni, ngenxa yamandla nokuthembeka kwayo. Imishayo ye-H neziteshi ziyizingxenye ezibalulekile ezinhlakeni zokwakha, ezihlinzeka ngokusekela okudingekayo kwemithwalo esindayo nokuqinisekisa ukuzinza kwezakhiwo.
Ukuphakama kokuhlolwa okuyimpumelelo kwensimbi emise okuka-L akubona nje kuphela ubufakazi bamakhono obunjiniyela ahilelekile kuphrojekthi ye-DUNE kodwa futhi kugqamisa ukubaluleka kwezinto ezisezingeni eliphezulu ekwakheni. Ukusebenzisana phakathi kososayensi, onjiniyela, nabahlinzeki abafana ne-Tianjin Reliance Steel kubalulekile empumelelweni yamaphrojekthi amakhulu kangaka, lapho ukunemba nokuthembeka kubaluleke kakhulu.
Njengoba iphrojekthi ye-DUNE iqhubeka, ithimba labakhi lizoqhubeka nokwenza izivivinyo kanye nokuphakamisa izingxenye zensimbi ezihlukahlukene, liqinisekise ukuthi isici ngasinye sihlangabezana nezidingo eziqinile ezibekwe onjiniyela balo msebenzi. Ukusetshenziswa kobuchwepheshe obuthuthukisiwe nezinto zokwakha kuzodlala indima ebalulekile empumelelweni iyonke yokuhlolwa, okuhloswe ngayo ukuvula imininingwane emisha ngokuziphatha kwama-neutrino kanye nemithelela yawo ekuqondeni kwethu indawo yonke.
Ukuhlola kwe-DUNE kulindeleke ukuthi kube nemithelela efinyelela kude emkhakheni we-particle physics futhi kungase kuphendule eminye yemibuzo ecindezela kakhulu mayelana nemvelo yento namandla ayisisekelo abusa indawo yonke. Njengoba umsebenzi wokwakha uqhubeka, ukubambisana phakathi kososayensi, onjiniyela, nabahlinzeki bempahla kuyoba kubalulekile ekuphumeleliseni lo msebenzi obalulekile.
Sengiphetha, ukuhlolwa okuyimpumelelo kokuphakanyiswa kwensimbi engamathani ayisithupha okumise okwe-L ye-Deep Underground Neutrino Experiment kumaka impumelelo ebalulekile ekwakhiweni kwalo mzamo wesayensi wokuvelela. Ngokusekelwa kwezinto zokwakha zekhwalithi ephezulu ezivela kubahlinzeki abafana ne-Tianjin Reliance Steel, iphrojekthi isisendleleni yokuba ngokoqobo. Njengoba iphrojekthi ye-DUNE iqhubeka, ithembisa ukunikela ngolwazi olubalulekile emkhakheni we-particle physics futhi ijulise ukuqonda kwethu ukusebenza okuyisisekelo kwendawo yonke. Ukusebenzisana phakathi kwababambe iqhaza abahlukahlukene kule phrojekthi kubonisa ukubaluleka kokusebenzisana kanye nokusungula izinto ezintsha ekubhekaneni nezinselele eziyinkimbinkimbi kakhulu zesayensi nobunjiniyela besimanje.
