Nā mea hoʻonui walaʻau haʻahaʻa Cryogenic

ʻO nā Cryogenic Low Noise Amplifiers (LNAs) he mau mea uila kūikawā i hoʻolālā ʻia e hoʻonui i nā hōʻailona nāwaliwali me ka walaʻau liʻiliʻi i hoʻohui ʻia, ʻoiai e hana ana ma nā mahana haʻahaʻa loa (ʻo ka maʻamau he mau mahana helium wai, 4K a i ʻole ma lalo). He mea koʻikoʻi kēia mau amplifiers i nā noi kahi e koʻikoʻi ai ka pono o ka hōʻailona a me ka ʻike, e like me ka quantumcomputing, radio astronomy, a me nā mea uila superconducting. Ma ka hana ʻana ma nā mahana cryogenic, loaʻa i nā LNA nā helu walaʻau haʻahaʻa loa i hoʻohālikelike ʻia me ko lākou mau hoa mahana lumi, e lilo ai lākou i mea nui loa i nā ʻōnaehana ʻepekema a me nā ʻenehana kiʻekiʻe.

Nā Hiʻohiʻona:

1. Kiʻi Walaʻau Haʻahaʻa Loa: Loaʻa i nā LNA cryogenic Rf nā helu walaʻau e like me kekahi mau hapaʻumi o ka decibel (dB), ʻoi aku ka maikaʻi ma mua o nā amplifiers mahana lumi. ʻO kēia ma muli o ka emi ʻana o ka walaʻau wela ma nā mahana cryogenic.
2. Loaʻa Kiʻekiʻe: Hāʻawi i ka hoʻonui ʻana i ka hōʻailona kiʻekiʻe (maʻamau 20-40 dB a ʻoi aku paha) e hoʻoikaika i nā hōʻailona nāwaliwali me ka ʻole o ka hoʻohaʻahaʻa ʻana i ka lākiō signal-to-noise (SNR).
3. Bandwidth Laulā: Kākoʻo i kahi ākea o nā alapine (frequencies), mai kekahi mau MHz a i kekahi mau GHz, ma muli o ka hoʻolālā a me ka noi.
4. Hoʻohālikelike Cryogenic: Nā mea hoʻonui walaʻau haʻahaʻa cryogenic microwave i hoʻolālā ʻia e hana pono ma nā mahana cryogenic (e laʻa, 4K, 1K, a i ʻole haʻahaʻa). Hana ʻia me ka hoʻohana ʻana i nā mea a me nā ʻāpana e mālama i ko lākou mau waiwai uila a me nā mechanical ma nā mahana haʻahaʻa.
5. Hoʻohana Mana Haʻahaʻa: Hoʻonohonoho ʻia no ka hoʻopuehu mana liʻiliʻi e pale aku i ka hoʻomehana ʻana i ke kaiapuni cryogenic, ka mea hiki ke hoʻopau i ka ʻōnaehana hoʻoluʻu.
6. Hoʻolālā liʻiliʻi a māmā: Hana ʻia no ka hoʻohui ʻana i nā ʻōnaehana cryogenic, kahi i kaupalena pinepine ʻia ai ka hakahaka a me ke kaumaha.
7. Linearity Kiʻekiʻe: Mālama i ka pono o ka hōʻailona ʻoiai ma nā pae mana hoʻokomo kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hoʻonui pololei me ka ʻole o ka hoʻopilikia ʻana.

Nā noi:

1. Ka helu ʻana o Quantum: Nā mea hoʻonui walaʻau haʻahaʻa cryogenic nalu Millimeter i hoʻohana ʻia i nā mea hana quantum superconducting e hoʻonui i nā hōʻailona heluhelu nāwaliwali mai nā qubits, e hiki ai ke ana pololei i nā kūlana quantum. Hoʻohui ʻia i loko o nā pahu hau dilution e hana ma nā mahana millikelvin.
2. Astronomy Lekiō: Hoʻohana ʻia i loko o nā mea hoʻokipa cryogenic o nā telescope lekiō e hoʻonui i nā hōʻailona palupalu mai nā mea lani mamao, e hoʻomaikaʻi ana i ka ʻike a me ka hoʻonā ʻana o nā nānā ʻana o ka hōkū.
3. Nā Uila Superconducting: nā mea hoʻonui walaʻau haʻahaʻa mm cryogenic i hoʻohana ʻia i nā kaapuni superconducting a me nā sensor e hoʻonui i nā hōʻailona nāwaliwali me ka mālama ʻana i nā pae walaʻau haʻahaʻa, e hōʻoiaʻiʻo ana i ka hana pololei a me ke ana ʻana o ka hōʻailona.
4. Nā Hoʻokolohua Haʻahaʻa-Mahana: Hoʻopili ʻia i nā hoʻonohonoho noiʻi cryogenic, e like me nā haʻawina o ka superconductivity, nā hanana quantum, a i ʻole ka ʻike ʻana i nā mea pouli, e hoʻonui i nā hōʻailona nāwaliwali me ka walaʻau liʻiliʻi.
5. Kiʻi Lapaʻau: Hoʻohana ʻia i nā ʻōnaehana kiʻi holomua e like me MRI (Magnetic Resonance Imaging) e hana ana ma nā mahana cryogenic e hoʻomaikaʻi i ka maikaʻi o ka hōʻailona a me ka hoʻonā.
6. Kamaʻilio Lewa a me ka Satellite: Hoʻohana ʻia i nā ʻōnaehana hoʻoluʻu cryogenic o nā mea hana lewa e hoʻonui i nā hōʻailona nāwaliwali mai ka lewa hohonu, e hoʻomaikaʻi ana i ka pono o ke kamaʻilio ʻana a me ka maikaʻi o ka ʻikepili.
7. ʻEpekema ʻEleʻele: Hoʻohana ʻia i loko o nā mea ʻike cryogenic no nā hoʻokolohua e like me ka ʻike ʻana i ka neutrino a i ʻole ka ʻimi ʻana i nā mea pouli, kahi e koʻikoʻi ai ka hoʻonui ʻana i ka walaʻau haʻahaʻa loa.
