HADDA LA XIRIIR

Attenuator waa qayb ka mid ah kantaroolka oo shaqadiisa ugu weyni ay tahay in la yareeyo xoogga calaamada ee dhexmarta attenuator-ka. Codsiyada la taaban karo, attenuators ayaa laga yaabaa inay ku shaqeeyaan jawi heerkul kala duwan, taasoo keenaysa attenuators go'an lcryogenic. Waxaan u qaabeynay attenuators jawiyada heerkulka hooseeya (-269 ~ + 125 darajo Celsius) anagoo dooranayna alaabta ceeriin ee ku haboon iyo hagaajinta heerka farsamada.

Attenuators go'an ee loo yaqaan 'Cryogenic attenuators' waxay leeyihiin kuleyl wanaagsan iyo xasillooni heerkul aad u hooseeya. Dhinaca kale, waxaa loo isticmaali karaa sida attenuators amplitude signal, iyo dhinaca kale, waxaa loo isticmaali karaa sida weel kulaylka wareejinta qabow. Waxaa loo isticmaali karaa dhinacyada sida sahaminta meel qoto dheer, falanqeeyayaasha raadiyaha, xisaabinta quantum-ka, iyo isgaarsiinta wireless-ka, gaar ahaan tijaabooyinka fiisigiska heerkulka hooseeya iyo cilmi baarista sare.

Ujeedada:

1. Attenuation Signal: Attenuators go'an heerkul hooseeya ayaa loo isticmaalaa in si sax ah loo yareeyo xoogga calaamadaha RF iyo microwave ee jawiga heerkulka aadka u hooseeya. Tani waxay muhiim u tahay ilaalinta qalabka xasaasiga ah ee soo dhaweynta iyo xakamaynta heerarka calaamadaha.
2. Xakamaynta qaylada: Iyadoo la yareynayo calaamada, buuqa iyo faragelinta nidaamka waa la dhimi karaa, taas oo hagaajinaysa saamiga signal-ilaa-sanqada (SNR) ee calaamadda.
3. Is-waafajinta Iswaafajinta: Heerkulka hoose ee attenuators go'an ayaa loo isticmaali karaa si loo waafajiyo caqabada nidaamka, si loo yareeyo milicsiga iyo hirarka taagan iyo hagaajinta waxqabadka nidaamka.

Codsiga:

1. Tijaabada Fiisigiska Cryogenic: Tijaabooyinka fiisigiska heerkulka hooseeya, heerkul hoose ayaa loo adeegsadaa si loo xakameeyo oo loo hagaajiyo xoogga calaamadaha. Tijaabooyinkani waxay inta badan ku lug leeyihiin daraasadda kondhomiyeyaasha sare, xisaabinta quantum iyo dhacdooyinka kale ee heerkulka hooseeya.
2. Cilmi-baarista Superconductor: Cilmi-baarista superconductor, attenuators go'an cryogenic waxaa loo isticmaalaa in lagu xakameeyo inta jeer ee raadiyaha iyo calaamadaha microwave-ka si loo barto sifooyinka iyo habdhaqanka superconductors.
3. Quantum Computing: Nidaamyada xisaabinta quantum-ka, attenuators-ka qaylo-dhaanta go'an ayaa loo adeegsadaa si loo xakameeyo xoogga signalada iyo isdhexgalka ka dhexeeya quantum bits (qubits). Tani waxay muhiim u tahay gaaritaanka hawlgallada xisaabinta tirada saxda ah ee saxda ah.
4. Astronomy iyo Radio Telescopes: Marka la eego astronomy iyo nidaamka telescope radio, attenuators go'an cryogenic waxaa loo isticmaalaa si loo hagaajiyo xoogga calaamadaha samada helay. Tani waxay gacan ka geysaneysaa hagaajinta tayada iyo saxnaanta xogta indha-indheynta.
5. Qalabka Elektaroonigga ah ee Cryogenic: Qalabka elektiroonigga ah ee heerkulka hooseeya, heerkulka hooseeya ee attenuators go'an ayaa loo isticmaalaa si loo xakameeyo loona hagaajiyo xoogga calaamadaha si loo hubiyo hawlgalka caadiga ah iyo waxqabadka sare ee qalabka.
Marka la soo koobo, attenuators go'an cryogenic ayaa si weyn loogu isticmaalaa dhinacyo badan sida tijaabooyinka fiisigiska cryogenic, cilmi baarista superconductor, xisaabinta quantum, xiddigiska, iyo qalabka elektiroonigga ah ee cryogenic. Waxay wanaajiyaan waxqabadka nidaamka iyo isku halaynta iyagoo si sax ah u xakameynaya xoogga calaamada oo yareynaya buuqa.

Qualwavesahayda kala duwan ee saxda ah ee saxda ah ee cryogenic attenuators go'an daboolo inta jeer ee kala duwan ee DC ~ 40GHz. Awoodda celceliska waa 2 watts. Attenuators waxaa loo isticmaalaa codsiyo badan oo loo baahan yahay dhimista awoodda.
