I-Attenuator yinxalenye yolawulo enomsebenzi wayo ophambili kukunciphisa amandla esignali adlula kwi-attenuator. Kwiindlela ezisebenzayo, ii-RF attenuators zinokusebenza kwiindawo ezahlukeneyo zobushushu, nto leyo ebangela ii-lcryogenic fixed attenuators. Siyile ii-attenuators kwiindawo eziphantsi zobushushu (-269~+125 degrees Celsius) ngokukhetha izinto ezifanelekileyo kunye nokuphucula umgangatho wetekhnoloji.

Ii-attenuator ezizinzileyo ze-cryogenic zinomoya oqhuba kakuhle wobushushu kunye nozinzo oluphezulu kumaqondo obushushu aphantsi kakhulu. Kwelinye icala, i-attenuator ye-microwave ingasetyenziswa njenge-attenuator ye-signal amplitude, kwaye kwelinye icala, i-millimeter wave attenuator ingasetyenziswa njenge-heat sinks yokudlulisa ubushushu. I-Mm wave attenuator ingasetyenziswa kwiindawo ezifana nokuhlola indawo enzulu, i-radio astronomy, i-quantum computing, kunye nonxibelelwano olungenazingcingo, ngakumbi kwi-low-temperature physics experiments kunye nophando lwe-superconductor.

Injongo:

1. Ukuncitshiswa kweSignali: Ii-attenuator ezizinzileyo ze-cryogenic zisetyenziselwa ukunciphisa ngokuchanekileyo amandla e-RF kunye ne-microwave signals kwiindawo ezishushu kakhulu. Oku kubalulekile ekukhuseleni izixhobo zokwamkela ezibuthathaka kunye namanqanaba okulawula isignali.
2. Ulawulo lweNgxolo: Ngokunciphisa isignali, ingxolo kunye nokuphazamiseka kwenkqubo kunokunciphisa, ngaloo ndlela kuphuculwe umlinganiselo wesignali-kwingxolo (SNR) yesignali.
3. Ukumatanisa Ukungathinteli: Ii-attenuators ezizinzileyo ze-Cryogenic zingasetyenziselwa ukufanisa ukuthinteli kwenkqubo, ngaloo ndlela zinciphisa ukubonakaliswa kunye namaza amiyo kwaye ziphucule ukusebenza kwenkqubo.

Isicelo:

Ezi mvavanyo zihlala ziquka uphononongo lwee-superconductors, i-quantum computing kunye nezinye izinto ezisebenzisa ubushushu obuphantsi.
2. Uphando lweSuperconductor: Kuphando lweSuperconductor, ii-cryogenic fixed attenuators zisetyenziselwa ukulungisa nokulawula i-radio frequency kunye ne-microwave signals ukufunda iimpawu kunye nokuziphatha kwee-superconductors.
3. I-Quantum Computing: Kwiinkqubo ze-quantum computing, i-cryogenic fixed attenuator isetyenziselwa ukulawula amandla esignali kunye nokusebenzisana phakathi kwee-quantum bits (qubits). Oku kubalulekile ekufezekiseni imisebenzi ye-quantum computing echanekileyo kakhulu.
4. Iiteleskopu zeenkwenkwezi kunye neeteleskopu zerediyo: Kwiinkqubo zeteleskopu zeenkwenkwezi kunye neeteleskopu zerediyo, ii-RF attenuators zisetyenziselwa ukulungisa amandla emiqondiso yesibhakabhaka efunyenweyo. Oku kunceda ukuphucula umgangatho kunye nokuchaneka kwedatha yokujonga.
5. Izixhobo ze-elektroniki ezisebenzisa i-Cryogenic: Kwizixhobo ze-elektroniki ezisebenzisa ubushushu obuphantsi, i-microwave attenuator isetyenziselwa ukulawula nokulungisa amandla esignali ukuqinisekisa ukusebenza okuqhelekileyo kunye nokusebenza okuphezulu kwezixhobo.
Ngamafutshane, ii-cryogenic fixed attenuators zisetyenziswa kakhulu kwiindawo ezininzi ezifana novavanyo lwe-cryogenic physics, uphando lwe-superconductor, i-quantum computing, i-astronomy, kunye nezixhobo ze-elektroniki ze-cryogenic. Ziphucula ukusebenza kwenkqubo kunye nokuthembeka ngokulawula ngokuchanekileyo amandla esignali kunye nokunciphisa ingxolo.
