Izikhulisi zeNgxolo ePhantsi zeCryogenic

Ii-Cryogenic Low Noise Amplifiers (ii-LNA) zizixhobo ze-elektroniki ezikhethekileyo ezenzelwe ukukhulisa imiqondiso ebuthathaka ngengxolo encinci eyongezelelweyo, ngelixa zisebenza kumaqondo obushushu aphantsi kakhulu (ngokwesiqhelo amaqondo obushushu e-helium angamanzi, i-4K okanye ngaphantsi). Ezi amplifiers zibaluleke kakhulu kwizicelo apho ukuthembeka kwesignali kunye novakalelo kubaluleke kakhulu, njenge-quantumcomputing, i-radio astronomy, kunye ne-superconducting electronics. Ngokusebenza kumaqondo obushushu e-cryogenic, ii-LNA zifumana amanani omsindo aphantsi kakhulu xa kuthelekiswa namaqondo obushushu egumbi, nto leyo eyenza ukuba zibe yimfuneko kwiinkqubo zesayensi kunye nezobuchwepheshe ezichanekileyo kakhulu.

Iimbonakalo:

1. Umfanekiso weNgxolo ePhantsi kakhulu: Ii-LNA ze-Rf cryogenic zifumana amanani engxolo aphantsi njengee-decibel ezimbalwa zeshumi (dB), nto leyo engcono kakhulu kune-amplifiers zobushushu begumbi. Oku kungenxa yokuncipha kwengxolo yobushushu kumaqondo obushushu e-cryogenic.
2. Inzuzo Ephezulu: Ibonelela ngokwandiswa kwesignali ephezulu (ngesiqhelo yi-20-40 dB okanye ngaphezulu) ukunyusa imiqondiso ebuthathaka ngaphandle kokunciphisa umlinganiselo wesignali-kwingxolo (SNR).
3. I-Bandwidth ebanzi: Ixhasa uluhlu olubanzi lweefrikhwensi, ukusuka kwi-MHz ezimbalwa ukuya kwi-GHz ezininzi, kuxhomekeke kuyilo kunye nokusetyenziswa.
4. Ukuhambelana kweCryogenic: Ii-amplifier ze-Microwave cryogenic eziphantsi zenzelwe ukusebenza ngokuthembekileyo kumaqondo obushushu e-cryogenic (umz., 4K, 1K, okanye nangaphantsi). Zenziwe kusetyenziswa izixhobo kunye nezinto ezigcina iipropati zazo zombane kunye nezoomatshini kumaqondo obushushu aphantsi.
5. Ukusetyenziswa kwamandla aphantsi: Kwenzelwe ukuchithwa kwamandla okuncinci ukuze kuthintelwe ukufudumeza imeko-bume engcolileyo, enokubangela ukuba inkqubo yokupholisa ingazinzi.
6. Uyilo oluNcinci noluKhawulezayo: Lwenzelwe ukudityaniswa kwiinkqubo ze-cryogenic, apho isithuba kunye nobunzima zihlala zilinganiselwe.
7. Umgca oPhezulu: Ugcina ukuthembeka kwesignali nokuba kumanqanaba aphezulu okufaka amandla, ukuqinisekisa ukwandiswa ngokuchanekileyo ngaphandle kokuphazamiseka.

Izicelo:

1. I-Quantum Computing: Ii-amplifiers ze-Millimeter wave cryogenic low noise ezisetyenziswa kwi-superconducting quantum processors ukukhulisa imiqondiso yokufunda ebuthathaka evela kwi-qubits, okuvumela ukulinganiswa ngokuchanekileyo kweemeko ze-quantum. Zidityaniswe kwiifriji ze-dilution ukuze zisebenze kumaqondo obushushu e-millikelvin.
2. I-Radio Astronomy: Isetyenziswa kwii-cryogenic receivers ze-radio telescopes ukukhulisa imiqondiso ebuthathaka evela kwizinto ezikude zasezulwini, ukuphucula uvakalelo kunye nokusombulula ukubonwa kweenkwenkwezi.
3. I-Superconducting Electronics: ii-mm wave cryogenic low noise amplifiers ezisetyenziswa kwiisekethe ze-superconducting kunye nee-sensors ukukhulisa imiqondiso ebuthathaka ngelixa zigcina amanqanaba aphantsi engxolo, ziqinisekisa ukucutshungulwa kunye nokulinganiswa ngokuchanekileyo kwesignali.
4. Iimvavanyo zoBushushu obuphantsi: Zisetyenziswa kwiiseti zophando ze-cryogenic, ezifana nezifundo ze-superconductivity, i-quantum phenomena, okanye ukufunyanwa kwezinto ezimnyama, ukukhulisa imiqondiso ebuthathaka ngengxolo encinci.
5. Imifanekiso yezonyango: Isetyenziswa kwiinkqubo zemifanekiso eziphambili ezifana ne-MRI (Magnetic Resonance Imaging) ezisebenza kumaqondo obushushu aqinileyo ukuphucula umgangatho wesignali kunye nesisombululo.
6. Unxibelelwano lweSithuba kunye neSathelayithi: Isetyenziswa kwiinkqubo zokupholisa ezisebenzisa izixhobo ezisebenzisa isithuba ukukhulisa imiqondiso ebuthathaka evela kwindawo enzulu, ukuphucula ukusebenza kakuhle konxibelelwano kunye nomgangatho wedatha.
7. I-Particle Physics: Isetyenziswa kwi-cryogenic detectors kwizilingo ezifana nokufumanisa i-neutrino okanye ukukhangela izinto ezimnyama, apho ukukhulisa ingxolo ephantsi kakhulu kubalulekile.
