Ngā Whakakaha Haruru Iti Cryogenic RF Ngaruiti Ngaru Mirimita mm ngaru
Ngā Whakakaha Haruru Iti Cryogenic
Ko ngā Whakakaha Haruru Iti Cryogenic (LNA) he taputapu hiko motuhake kua hangaia hei whakakaha i ngā tohu ngoikore me te iti o te haruru tāpiri, i te wā e mahi ana i ngā pāmahana tino iti (ko te nuinga he pāmahana helium wai, 4K, iti iho rānei). He mea nui ēnei whakakaha i roto i ngā tono e tino hira ana te pono me te aro o te tohu, pērā i te rorohiko irahiko, te whetū irirangi, me ngā hikohiko superconducting. Mā te mahi i ngā pāmahana cryogenic, ka eke ngā LNA ki ngā tatauranga haruru iti ake i ō rātou hoa pāmahana rūma, ka waiho hei mea nui i roto i ngā pūnaha pūtaiao me te hangarau tino tika.
Ngā Āhuatanga:
1. Ahua Haruru Tino Iti: Ka tutuki i ngā LNA tangi-ā-rangi RF ngā tatauranga haruru tae noa ki te torutoru whakatekau o te decibel (dB), he pai ake tēnei i ngā whakakaha pāmahana-rūma. Nā te whakaiti i te haruru wera i ngā pāmahana tangi-ā-rangi tēnei.
2. Teitei te Whiwhinga: Ka whakarato i te whakanui tohu teitei (te nuinga o te 20-40 dB, neke atu rānei) hei whakanui i ngā tohu ngoikore me te kore e whakaiti i te ōwehenga tohu-ki-haruru (SNR).
3. Whānuitanga o te Aratuku: Ka tautoko i te whānuitanga o ngā auautanga, mai i ētahi MHz ki ētahi GHz, i runga i te hoahoa me te tono.
4. Hototahi ki te Whakaohooho: Ko ngā whakakaha whakaohooho iti-haruru mō te ngaruiti kua hangaia kia mahi pono i ngā pāmahana whakaohooho (hei tauira, 4K, 1K, iti iho rānei). He mea hanga mā te whakamahi i ngā rauemi me ngā wāhanga e pupuri ana i ō rātou āhuatanga hiko me te hangarau i ngā pāmahana iti.
5. Te Iti o te Whakamahinga Mana: Kua arotauhia kia iti rawa te marara o te mana kia kore ai e wera te taiao cryogenic, ka whakararuraru pea i te pūnaha whakamatao.
6. Hoahoa Kiato, Mama hoki: I hangaia hei whakauru ki ngā pūnaha waikura, he iti noa te wāhi me te taumaha.
7. Teitei o te Raina: Ka mau tonu te pono o te tohu ahakoa ngā taumata mana whakauru teitei, kia tika ai te whakanui me te kore he hapa.
Ngā tono:
1. Rorohiko Kuantum: Ngā whakakaha haruru iti-ngaru mirimita e whakamahia ana i roto i ngā tukatuka kuantum superconducting hei whakakaha i ngā tohu pānui ngoikore mai i ngā qubit, e taea ai te ine tika i ngā āhua kuantum. Kua whakauruhia ki roto i ngā pouaka whakamātao waimeha hei mahi i ngā pāmahana mirimiri-kervin.
2. Te Tātaritanga whetū reo irirangi: Ka whakamahia i roto i ngā kaiwhiwhi tangihanga o ngā karu whakaata reo irirangi hei whakanui ake i ngā tohu ngoikore mai i ngā mea tawhiti o te rangi, hei whakapai ake i te aro me te taumira o ngā kitenga whetū.
3. Ngā Hikohiko Whakahaere-rahi: ngā whakakaha haruru iti-ngaru mm e whakamahia ana i roto i ngā ara iahiko whakahaere-rahi me ngā pūoko hei whakakaha i ngā tohu ngoikore me te pupuri tonu i ngā taumata haruru iti, kia tika ai te tukatuka tohu me te ine.
4. Ngā Whakamātautau Pāmahana-Iti: Whakamahia i roto i ngā rangahau cryogenic, pērā i ngā rangahau mō te superconductivity, ngā āhuatanga matū, te kimi rānei i ngā mea pōuri, hei whakanui ake i ngā tohu ngoikore me te iti rawa o te haruru.
5. Whakaahua Hauora: Whakamahia ai i roto i ngā pūnaha whakaahua matatau pēnei i te MRI (Magnetic Resonance Imaging) e mahi ana i ngā pāmahana cryogenic hei whakarei ake i te kounga me te taumira o te tohu.
6. Whakawhitiwhiti Kōrero ā-Wāhi me te Amiorangi: Whakamahia ai i roto i ngā pūnaha whakamatao cryogenic o ngā taputapu ā-wāhi hei whakanui ake i ngā tohu ngoikore mai i te wāhi hōhonu, hei whakapai ake i te whai huatanga o te whakawhitiwhiti kōrero me te kounga raraunga.
7. Ahupūngao Matūriki: Whakamahia i roto i ngā pūoko tangi mō ngā whakamātautau pēnei i te kimi neutrino, te rapu rānei i ngā mea pōuriuri, ina he mea nui te whakanui i te haruru tino iti.
Qualwavee whakarato ana i ngā Whakakaha Haruru Iti Cryogenic mai i DC ki 8GHz, ā, ka taea te pāmahana haruru te iti rawa ki te 10K.
