Attenuator ndi gawo lowongolera lomwe ntchito yake yayikulu ndikuchepetsa mphamvu yazizindikiro kudutsa pa attenuator. Pakugwiritsa ntchito, zoziziritsa kukhosi zimatha kugwira ntchito m'malo osiyanasiyana kutentha, zomwe zimapangitsa kuti lcryogenic fixed attenuators. Tapanga zoziziritsira kumadera otentha otsika (-269~+125 digiri Celsius) posankha zida zoyenera ndikuwongolera luso laukadaulo.

Ma Cryogenic fixed attenuators amakhala ndi matenthedwe abwino komanso okhazikika pamatenthedwe otsika kwambiri. Kumbali imodzi, amatha kugwiritsidwa ntchito ngati ma sign amplitude attenuators, ndipo kumbali ina, atha kugwiritsidwa ntchito ngati zozama za kutentha kwa kusamutsa kuzizira. Ikhoza kugwiritsidwa ntchito m'magawo monga kufufuza kwakuya kwamlengalenga, zakuthambo za wailesi, quantum computing, ndi kulankhulana opanda zingwe, makamaka pakuyesa kwafizikiki yotsika kwambiri ndi kafukufuku wapamwamba kwambiri.

Cholinga:

1. Kuchepetsa kwa Signal: Zowongolera zokhazikika zotsika kutentha zimagwiritsidwa ntchito kutsitsa molondola mphamvu ya RF ndi ma siginecha a microwave m'malo otentha kwambiri. Izi ndizofunikira poteteza zida zolandirira tcheru ndikuwongolera ma siginecha.
2. Kuwongolera Phokoso: Mwa kuchepetsa chizindikiro, phokoso ndi kusokoneza dongosolo kungachepetsedwe, motero kumapangitsa kuti chiŵerengero cha chizindikiro cha phokoso (SNR) chikhale bwino.
3. Kufananiza Impedance: Zowongolera zotsika zotsika zimatha kugwiritsidwa ntchito kuti zigwirizane ndi kusokoneza kwa dongosolo, potero kuchepetsa kuwunikira ndi mafunde oyimirira ndikuwongolera magwiridwe antchito.

Ntchito:

1. Kuyesera kwa fizikiki ya Cryogenic: Pakuyesa kwafizikiki yotsika kwambiri, zoyezera zotsika zokhazikika zimagwiritsidwa ntchito kuwongolera ndikusintha mphamvu yazizindikiro. Kuyesera kumeneku nthawi zambiri kumaphatikizapo kuphunzira kwa superconductors, quantum computing ndi zochitika zina zotsika kutentha.
2. Kafukufuku wa Superconductor: Mu kafukufuku wa superconductor, ma cryogenic fixed attenuators amagwiritsidwa ntchito kuwongolera ndi kuwongolera ma frequency a radio ndi ma siginecha a microwave kuti aphunzire mawonekedwe ndi machitidwe a superconductors.
3. Quantum Computing: Mu machitidwe a quantum computing, cryogenically fixed attenuators amagwiritsidwa ntchito kulamulira mphamvu za chizindikiro ndi kuyanjana pakati pa quantum bits (qubits). Izi ndizofunikira kwambiri kuti mukwaniritse magwiridwe antchito apamwamba kwambiri a quantum computing.
4. Astronomy ndi Radio Telescopes: M’kachitidwe ka zakuthambo ndi telesikopu ya wailesi, zoyambukirira zosakhazikika za cryogenic zimagwiritsidwa ntchito kukonza mphamvu ya zizindikiro zakuthambo zolandiridwa. Izi zimathandiza kuwongolera bwino komanso kulondola kwa data yowonera.
5. Cryogenic Electronic Equipment: Mu zipangizo zamagetsi zotsika kwambiri, zochepetsera zochepetsera kutentha zimagwiritsidwa ntchito poyang'anira ndi kusintha mphamvu ya chizindikiro kuti zitsimikizidwe kuti zimagwira ntchito bwino komanso zimagwira ntchito bwino.
Mwachidule, ma cryogenic fixed attenuators amagwiritsidwa ntchito kwambiri m'magawo ambiri monga kuyesa kwa fizikisi ya cryogenic, kafukufuku wa superconductor, quantum computing, zakuthambo, ndi zida zamagetsi za cryogenic.. Amawongolera magwiridwe antchito ndi kudalirika kwamakina powongolera bwino mphamvu yazizindikiro ndi kuchepetsa phokoso.

Qualwaveimapereka ma attenuators osiyanasiyana olondola kwambiri a cryogenic omwe amaphimba ma frequency osiyanasiyana DC ~ 40GHz. Mphamvu yapakati ndi 2 watts. Ma attenuators amagwiritsidwa ntchito pazinthu zambiri pomwe kuchepetsa mphamvu kumafunikira.
