ʻO ka Attenuator kahi mea hoʻomalu nona ka hana nui e hōʻemi i ka ikaika hōʻailona e hele ana ma o ka attenuator. Ma nā hoʻohana pono, hiki ke hana nā attenuators i nā ʻano wela like ʻole, e hāʻawi ana i nā attenuators paʻa lcryogenic. Ua hoʻolālā mākou i nā attenuators no nā kaiapuni haʻahaʻa haʻahaʻa (-269 ~ + 125 degere Celsius) ma ke koho ʻana i nā mea maka kūpono a me ka hoʻomaikaʻi ʻana i ke kiʻekiʻe o ka ʻenehana.
Cryogenic paʻa attenuators i maikai thermal conductivity a kiʻekiʻe paʻa i loa haʻahaʻa wela. Ma kekahi ʻaoʻao, hiki ke hoʻohana ʻia e like me ka hōʻailona amplitude attenuators, a ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻohana ʻia e like me ka wela wela no ka hoʻololi anu. Hiki ke hoʻohana ʻia i nā kula e like me ka ʻimi ʻana i ka lewa hohonu, radio astronomy, quantum computing, a me ke kamaʻilio uila, ʻoi aku hoʻi i nā hoʻokolohua physics haʻahaʻa a me ka noiʻi superconductor.
1. Hōʻailona hōʻailona: Hoʻohana ʻia nā attenuators paʻa wela haʻahaʻa e hoʻemi pono i ka ikaika o RF a me nā hōʻailona microwave ma nā wahi wela haʻahaʻa loa. He mea koʻikoʻi kēia no ka pale ʻana i nā lako hoʻokipa koʻikoʻi a me ka mālama ʻana i nā pae hōʻailona.
2. Noise Control: Ma ka ho'ēmiʻana i ka hōʻailona, hiki ke hoʻemiʻia ka walaʻau a me ke keakea i loko o ka pūnaewele, a laila e hoʻomaikaʻi ai i ka ratio signal-to-noise (SNR) o ka hōʻailona.
3. Hoʻohālikelike Impedance: Hiki ke hoʻohana ʻia nā attenuators paʻa haʻahaʻa haʻahaʻa e hoʻohālikelike i ka impedance o ka ʻōnaehana, no laila e hōʻemi ana i nā noʻonoʻo a me nā nalu kū a hoʻomaikaʻi i ka hana ʻōnaehana.
1. ʻO ka hoʻokolohua physics cryogenic: Ma nā hoʻokolohua hoʻokolohua haʻahaʻa haʻahaʻa, hoʻohana ʻia nā attenuators paʻa haʻahaʻa e hoʻomalu a hoʻoponopono i ka ikaika o ka hōʻailona. Hoʻopili pinepine kēia mau hoʻokolohua i ke aʻo ʻana i nā superconductors, quantum computing a me nā mea haʻahaʻa haʻahaʻa haʻahaʻa.
2. Superconductor Research: Ma ka noiʻi superconductor, hoʻohana ʻia nā attenuators paʻa cryogenic no ka hoʻoponopono ʻana a me ka mālama ʻana i nā lekiō a me nā hōʻailona microwave e aʻo ai i nā waiwai a me nā ʻano o nā superconductor.
3. Quantum Computing: Ma nā ʻōnaehana quantum computing, hoʻohana ʻia nā attenuators cryogenically i hoʻopaʻa ʻia e hoʻoponopono i ka ikaika hōʻailona a me nā pilina ma waena o nā kuantum bits (qubits). He mea koʻikoʻi kēia no ka hoʻokō ʻana i nā hana helu helu helu kiʻekiʻe.
4. Astronomy a me Radio Telescopes: I ka astronomy and radio telescope system, cryogenic fixed attenuators hoʻohana 'ia e hoʻololi i ka ikaika o nā hōʻailona lani. Kōkua kēia i ka hoʻomaikaʻi ʻana i ka maikaʻi a me ka pololei o ka ʻikepili nānā.
5. Cryogenic Electronic Equipment: I loko o nā lako uila haʻahaʻa haʻahaʻa, hoʻohana ʻia nā attenuators paʻa haʻahaʻa haʻahaʻa e hoʻomalu a hoʻoponopono i ka ikaika hōʻailona e hōʻoia i ka hana maʻamau a me ka hana kiʻekiʻe o nā mea hana.
I ka pōkole, hoʻohana nui ʻia nā attenuators paʻa cryogenic i nā kula he nui e like me nā hoʻokolohua cryogenic physics, noiʻi superconductor, quantum computing, astronomy, a me nā lako uila cryogenic.. Hoʻomaikaʻi lākou i ka hana ʻōnaehana a me ka hilinaʻi ma o ka hoʻomalu pono ʻana i ka ikaika hōʻailona a me ka hōʻemi ʻana i ka walaʻau.
KaʻaleʻaleʻaHāʻawi i nā attenuators paʻa paʻa kiʻekiʻe kiʻekiʻe e uhi i ka laina alapine DC ~ 40GHz. ʻO ka mana maʻamau he 2 watts. Hoʻohana ʻia nā attenuators i nā noi he nui kahi e pono ai ka emi ʻana o ka mana.
