antarctic muon aur nutrino detector sarani

antarctic muon aur nutrino detector sarani (amanda) amundsen-scott dakshin dhruv station key neeche sthit ack nutrino doorbeen haye. 2005 mein, nau saal key sanchaalan key baad, amanda aadhikarik taur parr apani uttaradhikari pariyojana, icube nutrino vedhshala kaa hissa bunn gayaa.
amanda mein optical module hotey hain, jinamen seey pratyek mein ack photomultiplier tube hoti haye, joe lagbhag 1500 seey 1900 meater kii gaharaai parr antarctic burf kii topi mein doob jaati haye. apane navintam vikas charan mein, jise amanda-3 key roop mein jaanaa jaataa haye, amanda 19 alag-alag taaron parr lagey 677 optical module kii ack sarani seey banaa haye joe 200 meater key vyaas key saath ack khurdare vritt mein faila huaa haye. pratyek string mein kaee darjan module hotey hain, aur germ paani kii nully kaa upayog karke burf mein ack chhed "drilling" karke, judey optical module key saath cable koo dubakar, aur phir burf koo isake chaaron or jamane dete hue rakhaa gayaa thaa.
amanda bahut uchch oorjaa vaale nutrino (50 + jee. ee. vee.) kaa pataa lagaata haye joe uttari golardh seey prithvi seey gujarate hain aur phir pratikriya karate hain jaise hii way antarctic burf key madhyam seey oopar kii or jaa rahey hain. nutrino kamjor paramanu bull key madhyam seey aspas key paani kii burf mein nihit oxygen yaa hydrogen parmaanuon key naabhik key saath baatchit kartaa haye, jisase ack muon aur ack purani bauchhar hoti haye. optical module inn baad key kanon seey cherenkov vikiran kaa pataa lagaate hain, aur photon hitt key samay key vishleshan seey lagbhag 2 degree key sthaanik resolution key saath mool nutrino kii disha nirdhaarit kii jaa sakati haye.
amanda kaa lakshya nutrino khagol vigyaan kaa ack prayaas thaa, jisamen nutrino key atirikt-saur sroton kii pehchaan aur lakshan varnan kiya gayaa thaa. japan mein super-kamiyokande jaise bhoomigat detectors kii tulanaa mein, amanda uchch oorjaa nutrino koo dekhane mein saksham thaa kyonki yeh maanav nirmit tank taka matra mein seemit naheen haye; haalaanki, cumm niyantrit sthitiyon aur photomultipliers key vyaapak antaral key kaaran isaki sateekta bahut cumm thee. super-kamiyokande soorya seey nutrino aur prithvi key vayumandal mein utpann honey vaale nutrino parr bahut adhik vistaar seey dekh sakate hain; haalaanki, uchch oorjaa parr, spectrum mein saur mandal key baahar key sroton seey nutrino kaa prabhutva honah chaahiye. brahmand mein iss tarah kaa ack nayaa drishtikon kaale padaarth aur anya khagoliya ghatnaaon kii khoj mein mahatvapurna surag dey sakata haye.
icube key hisse key roop mein dou saal key ekikrit sanchaalan key baad, amanda ginati ghar (martin aeye mein. pomerantz vedhshala) koo julaai aur agast 2009 mein sevamukt curr diyaa gayaa thaa.
