Attenuator ndi gawo lowongolera lomwe ntchito yake yayikulu ndi kuchepetsa mphamvu ya chizindikiro chomwe chimadutsa mu attenuator. Mu ntchito zenizeni, ma RF attenuator amatha kugwira ntchito m'malo osiyanasiyana otentha, zomwe zimapangitsa kuti pakhale ma lcryogenic fixed attenuator. Tapanga ma attenuator a malo otentha otsika (-269~+125 degrees Celsius) posankha zinthu zoyenera zopangira ndikukweza mulingo waukadaulo.

Zotchingira kutentha zokhazikika za cryogenic zimakhala ndi mphamvu yabwino yoyendetsera kutentha komanso kukhazikika kwambiri kutentha kotsika kwambiri. Kumbali imodzi, chotchingira kutentha cha microwave chingagwiritsidwe ntchito ngati zotchingira kutentha kwa chizindikiro, ndipo kumbali ina, chotchingira kutentha cha millimeter chingagwiritsidwe ntchito ngati zotenthetsera kutentha kuti chisamutse kutentha kozizira. Chotchingira kutentha cha Mm chingagwiritsidwe ntchito m'magawo monga kufufuza kwakuya kwa malo, zakuthambo za wailesi, quantum computing, ndi kulumikizana popanda zingwe, makamaka mu kuyesa kwa fizikiki kotsika kutentha komanso kafukufuku wa superconductor.

Cholinga:

1. Kuchepetsa Mphamvu ya Chizindikiro: Zochepetsera mphamvu ya cryogenic zimagwiritsidwa ntchito kuchepetsa mphamvu ya zizindikiro za RF ndi microwave m'malo otentha kwambiri. Izi ndizofunikira poteteza zida zolandirira zomwe zimakhudzidwa kwambiri komanso kuwongolera kuchuluka kwa zizindikiro.
2. Kuwongolera Phokoso: Mwa kuchepetsa chizindikiro, phokoso ndi kusokoneza mu dongosolo zitha kuchepetsedwa, motero kusintha chiŵerengero cha chizindikiro-ku-phokoso (SNR) cha chizindikirocho.
3. Kufananiza Impedance: Zochepetsera mphamvu za cryogenic zitha kugwiritsidwa ntchito kuti zigwirizane ndi impedance ya dongosolo, potero zimachepetsa kuwunikira ndi mafunde oyima ndikukweza magwiridwe antchito a dongosolo.

Ntchito:

1. Kuyesera kwa cryogenic physics: Mu kuyesa kwa fizikisi yotsika kutentha, ma cryogenic fixed attenuators amagwiritsidwa ntchito kuwongolera ndikusintha mphamvu ya chizindikiro. Kuyesera kumeneku nthawi zambiri kumaphatikizapo kuphunzira za ma superconductors, quantum computing ndi zochitika zina zotsika kutentha.
2. Kafukufuku wa Superconductor: Mu kafukufuku wa superconductor, ma cryogenic fixed attenuators amagwiritsidwa ntchito kukonza ndikuwongolera ma frequency a wailesi ndi ma microwave kuti aphunzire makhalidwe ndi khalidwe la ma superconductors.
3. Kuwerengera kwa Quantum: Mu makina owerengera a quantum, cryogenic fixed attenuator imagwiritsidwa ntchito kuwongolera mphamvu ya chizindikiro ndi kuyanjana pakati pa ma quantum bits (qubits). Izi ndizofunikira kwambiri kuti pakhale ntchito zowerengera za quantum zolondola kwambiri.
4. Ma Telescope a Kuthambo ndi Ma Telescope a Pawailesi: Mu makina a telescope a zakuthambo ndi ma telescope a pawailesi, ma attenuator a RF amagwiritsidwa ntchito kusintha mphamvu ya zizindikiro zakuthambo zomwe zalandiridwa. Izi zimathandiza kukonza ubwino ndi kulondola kwa deta yowonera.
5. Zipangizo Zamagetsi Zozizira: Mu zipangizo zamagetsi zotentha pang'ono, chochepetsera kutentha cha microwave chimagwiritsidwa ntchito kuwongolera ndikusintha mphamvu ya chizindikiro kuti zitsimikizire kuti zikugwira ntchito bwino komanso kuti chipangizocho chikugwira ntchito bwino.
Mwachidule, ma cryogenic fixed attenuators amagwiritsidwa ntchito kwambiri m'magawo ambiri monga kuyesa kwa cryogenic physics, kafukufuku wa superconductor, quantum computing, zakuthambo, ndi zida zamagetsi za cryogenic. Amathandizira magwiridwe antchito ndi kudalirika kwa dongosolo mwa kuwongolera bwino mphamvu ya chizindikiro ndikuchepetsa phokoso.

Qualwaveimapereka ma attenuator osiyanasiyana olondola kwambiri a cryogenic fixed attenuators omwe amaphimba ma frequency range DC ~ 40GHz. Mphamvu yapakati ndi ma watts awiri. Ma attenuator amagwiritsidwa ntchito m'njira zambiri pomwe mphamvu imafunika kuchepetsedwa.
