Zokulitsa Phokoso Lochepa la Cryogenic

Ma Cryogenic Low Noise Amplifiers (LNAs) ndi zipangizo zamagetsi zapadera zomwe zimapangidwa kuti ziwonjezere zizindikiro zofooka ndi phokoso lochepa, pomwe zimagwira ntchito kutentha kotsika kwambiri (nthawi zambiri kutentha kwa helium yamadzimadzi, 4K kapena pansi pake). Ma amplifiers awa ndi ofunikira kwambiri pakugwiritsa ntchito komwe kukhulupirika kwa chizindikiro ndi kukhudzidwa ndikofunikira kwambiri, monga quantumcomputing, radio astronomy, ndi superconducting electronics. Mwa kugwira ntchito kutentha kotsika, ma LNA amapeza ziwerengero zochepa za phokoso poyerekeza ndi anzawo kutentha kwa chipinda, zomwe zimapangitsa kuti akhale ofunikira kwambiri m'makina asayansi ndi ukadaulo olondola kwambiri.

Mawonekedwe:

1. Chithunzi cha Phokoso Lochepa Kwambiri: Ma LNA a Rf cryogenic amakhala ndi ziwerengero za phokoso zotsika kwambiri mpaka magawo khumi a decibel (dB), zomwe zimakhala bwino kwambiri kuposa ma amplifiers a kutentha kwa chipinda. Izi zimachitika chifukwa cha kuchepa kwa phokoso la kutentha pa kutentha kwa cryogenic.
2. Kupeza Mphamvu Kwambiri: Kumapereka kukulitsa mphamvu ya chizindikiro (nthawi zambiri 20-40 dB kapena kuposerapo) kuti chiwonjezere mphamvu ya chizindikiro chofooka popanda kuchepetsa chiŵerengero cha chizindikiro-ku-phokoso (SNR).
3. Bandwidth Yonse: Imathandizira ma frequency osiyanasiyana, kuyambira MHz ochepa mpaka GHz angapo, kutengera kapangidwe ndi momwe imagwiritsidwira ntchito.
4. Kugwirizana kwa Cryogenic: Ma amplifiers a cryogenic otsika phokoso la microwave omwe adapangidwa kuti azigwira ntchito moyenera kutentha kwa cryogenic (monga 4K, 1K, kapena kutsika). Amapangidwa pogwiritsa ntchito zipangizo ndi zigawo zomwe zimasunga mphamvu zawo zamagetsi ndi makina kutentha kochepa.
5. Kugwiritsa Ntchito Mphamvu Yochepa: Yokonzedwa bwino kuti isamatenthetse mphamvu zambiri kuti isatenthetse malo omwe amazizira kwambiri, zomwe zingasokoneze dongosolo loziziritsira.
6. Kapangidwe Kakang'ono Komanso Kopepuka: Kopangidwa kuti kaphatikizidwe mu makina ozungulira, komwe malo ndi kulemera nthawi zambiri zimakhala zochepa.
7. Kulunjika Kwambiri: Kumasunga umphumphu wa chizindikiro ngakhale pamlingo wapamwamba wa mphamvu yolowera, kuonetsetsa kuti kukulitsa molondola popanda kusokoneza.

Mapulogalamu:

1. Quantum Computing: Ma Millimeter wave cryogenic low noise amplifiers omwe amagwiritsidwa ntchito pokonza ma quantum processors kuti awonjezere zizindikiro zofooka zowerengera kuchokera ku qubits, zomwe zimathandiza kuyeza molondola momwe quantum imagwirira ntchito. Amaphatikizidwa mu dilutionrefrigerators kuti azigwira ntchito pa kutentha kwa millikelvin.
2. Kuonera Zakuthambo pa Ma Radio: Kumagwiritsidwa ntchito mu ma telescope a wailesi omwe amalandira zinthu zobisika kuti awonjezere zizindikiro zosamveka bwino kuchokera ku zinthu zakutali zakuthambo, ndikuwonjezera mphamvu ya kuwona zakuthambo ndi kutsimikiza kwa zomwe zikuchitika.
3. Superconducting Electronics: ma mm wave cryogenic low noise amplifiers omwe amagwiritsidwa ntchito m'mabwalo oyendetsera superconducting ndi masensa kuti awonjezere ma signali ofooka pamene akusunga phokoso lochepa, kuonetsetsa kuti ma signali akugwiritsidwa ntchito molondola komanso kuyeza molondola.
4. Kuyesera Kotsika kwa Kutentha: Kumagwiritsidwa ntchito mu kafukufuku wa cryogenic, monga maphunziro a superconductivity, quantum phenomena, kapena kuzindikira zinthu zakuda, kuti kuwonjezere zizindikiro zofooka ndi phokoso lochepa.
5. Kujambula Zachipatala: Kumagwiritsidwa ntchito m'makina apamwamba ojambulira zithunzi monga MRI (Magnetic Resonance Imaging) omwe amagwira ntchito kutentha kwa cryogenic kuti awonjezere ubwino wa chizindikiro ndi kukana kwake.
6. Kulankhulana kwa Mumlengalenga ndi Satellite: Kumagwiritsidwa ntchito mu makina ozizira a cryogenic a zida zochokera mumlengalenga kuti ziwonjezere zizindikiro zofooka kuchokera mumlengalenga, ndikukweza magwiridwe antchito a kulumikizana komanso mtundu wa deta.
7. Fiziki ya Tinthu Tating'onoting'ono: Imagwiritsidwa ntchito mu zida zowunikira za cryogenic poyesa monga kuzindikira neutrino kapena kufufuza zinthu zakuda, komwe kukulitsa phokoso lotsika kwambiri ndikofunikira kwambiri.

Qualwaveimapereka ma Cryogenic Low Noise Amplifiers kuyambira DC mpaka 8GHz, ndipo kutentha kwa phokoso kumatha kufika pa 10K.
