Kufunyenwe iiPulsar ezintsha ezingaphezu kwama-900: Ukusetyenziswa kobuchwepheshe beLaser kwiTelescope ekhawulezayo yaseTshayina

Kutshanje, i-FAST Telescope yaseTshayina ifumene ngempumelelo ii-pulsars ezintsha ezingaphezu kwama-900. Le mpumelelo ayigcini nje ngokutyebisa intsimi yeenkwenkwezi kodwa ikwabonelela ngemibono emitsha ngemvelaphi kunye nokuguquka kwendalo yonke. I-FAST ixhomekeke kuthotho lwetekhnoloji ephucukileyo, kwaye itekhnoloji yelaser (ukwenziwa ngokuchanekileyo, ukulinganisa kunye nokubeka indawo, ukuwelda kunye nokudibanisa, kunye nokupholisa ngelaser...) idlala indima ebalulekileyo.

I-FAST Telescope yaseTshayina, iteleskopu enkulu yerediyo engqukuva enobubanzi obuziimitha ezingama-500 kwiphondo laseGuizhou, iphinde yathimba ihlabathi ngokufumanisa okumangalisayo. Kutshanje, i-FAST ifumene ngempumelelo iipulsars ezintsha ezingaphezu kwama-900. Le mpumelelo ayigcini nje ngokutyebisa icandelo leenkwenkwezi kodwa ikwabonelela ngemibono emitsha ngemvelaphi kunye nokuguquka kwendalo iphela.

Ukuze kubanjwe amaza erediyo abuthathaka avela kwiindawo ezikude zendalo iphela — amaza agcina iimfihlo zeegalaksi ezikude, iipulsars, kunye neemolekyuli eziphakathi kweenkwenkwezi — i-FAST ixhomekeke kuthotho lwetekhnoloji ephucukileyo.

Indima Ebalulekileyo Yobuchwepheshe BeLaser Kulwakhiwo LweFAST

Ukuvelisa ngokuchanekileyo

Umphezulu okhanyayo we-FAST wenziwe ngamawakawaka eephaneli ezahlukeneyo, kwaye indawo echanekileyo kunye nokulungiswa kwezi paneli kubalulekile ekuqwalaselweni kobukrelekrele obuphezulu. Itekhnoloji yelaser idlala indima ebalulekileyo kule nkqubo. Ngokusika nokumakisha ngokuchanekileyo kwelaser, iqinisekisa ukwenziwa ngokuchanekileyo kwecandelo ngalinye, igcina imo echanekileyo kunye nozinzo lomphezulu okhanyayo.

Ukulinganisa kunye nokuBeka indawo

Ukuze kufezekiswe ukujolisa ngokuchanekileyo, iteknoloji yokulinganisa i-laser isetyenziselwa ukulinganisa ngokuchanekileyo nokulungisa iindawo zeeyunithi ezibonisa ukukhanya. Ukusetyenziswa kweenkqubo zokulandelela i-laser kunye nokwahlulahlula kuphucula kakhulu ukuchaneka nokusebenza kakuhle kokujonga.

Ukuwelda kunye noQhagamshelo

Ngexesha lokwakhiwa kwe-FAST, iteknoloji yokuwelda nge-laser yasetyenziswa ukuqhagamshela iintambo ezininzi zentsimbi kunye nezakhiwo ezixhasayo. Le ndlela yokuwelda echanekileyo nesebenzayo iqinisekisa uzinzo kunye nokuthembeka kwesakhiwo seteleskopu.

Ii-Laser Chillers : Ukuqinisekisa Ukusebenza Okuzinzileyo Kwezixhobo Zelaser

Ekusebenzeni kwe-FAST, ii-laser chillers zidlala indima ebalulekileyo. Zilawula ubushushu bendawo yokusebenza yezixhobo ze-laser ngokusebenzisa amanzi abandayo ajikelezayo, ziqinisekisa ukuba izixhobo zisebenza kwiimeko ezifanelekileyo. Oku, kuqinisekisa ukuchaneka kokucubungula kunye nokulinganisa kwe-laser, okuphucula uzinzo kunye nokusebenza kakuhle kwenkqubo.

Ukwakhiwa nokusebenza kwe-FAST akubonisi nje kuphela indima ebalulekileyo yetekhnoloji yelaser kwi-astronomy yanamhlanje kodwa kukwaphawula isahluko esitsha ekuphononongeni kwabantu indalo iphela. Njengoko i-FAST iqhubeka nokusebenza kwayo nophando, silindele ukuba iza kutyhila iimfihlo ezingaphezulu zendalo iphela, iqhubele phambili kwi-astronomy nakwiindawo zesayensi ezinxulumene noko.
