Li-Amplifiers tsa Lerata le Tlase la Cryogenic

Li-Amplifiers tsa Lerata le Tlase la Cryogenic (LNAs) ke lisebelisoa tse khethehileng tsa elektroniki tse etselitsoeng ho holisa matšoao a fokolang ka lerata le fokolang le ekelitsoeng, ha li ntse li sebetsa mochesong o tlase haholo (hangata mochesong oa helium e metsi, 4K kapa ka tlase). Li-amplifier tsena li bohlokoa lits'ebetsong moo botšepehi ba matšoao le kutlo li leng tsa bohlokoa, joalo ka quantumcomputing, bolepi ba linaleli ba radio, le superconducting electronics. Ka ho sebetsa mochesong oa cryogenic, li-LNA li fihlella lipalo tsa lerata tse tlase haholo ha li bapisoa le tsa tsona tsa mocheso oa kamore, e leng se etsang hore li be tsa bohlokoa haholo litsamaisong tsa saense le theknoloji tse nepahetseng haholo.

Likaroloana:

1. Setšoantšo sa Lerata le Tlase ka ho Fetisisa: Li-LNA tse nang le molumo o matla li fumana lipalo tsa lerata tse ka tlase ho karolo ea leshome ea decibel (dB), e leng se betere haholo ho feta li-amplifier tsa mocheso oa kamore. Sena se bakoa ke phokotso ea lerata la mocheso mochesong o matla.
2. Phaello e Phahameng: E fana ka keketseho e phahameng ea lets'oao (hangata 20-40 dB kapa ho feta) ho eketsa matšoao a fokolang ntle le ho fokotsa karolelano ea lets'oao-ho-lerata (SNR).
3. Bandwidth e Sephara: E tšehetsa mefuta e mengata ea maqhubu, ho tloha ho MHz tse 'maloa ho isa ho GHz tse' maloa, ho latela moralo le ts'ebeliso.
4. Ho Sebedisana ha Cryogenic: Di-amplifier tsa lerata le tlase la cryogenic tsa microwave tse etseditsweng ho sebetsa ka botshepehi maemong a mocheso a cryogenic (mohlala, 4K, 1K, kapa esita le ka tlase). Di hahilwe ka thepa le dikarolo tse bolokang thepa ya tsona ya motlakase le ya mechini maemong a mocheso a tlase.
5. Tšebeliso e Tlase ea Matla: E ntlafalitsoe bakeng sa ho qhalana ha matla ho fokolang ho qoba ho futhumatsa tikoloho e cryogenic, e ka sitisang sistimi ea ho pholisa.
6. Moralo o Monyenyane le o Bobebe: E entsoe bakeng sa ho kopanngoa le litsamaiso tsa cryogenic, moo sebaka le boima hangata li lekanyelitsoeng.
7. Ho ba le mola o phahameng: E boloka botšepehi ba lets'oao esita le maemong a phahameng a matla a ho kenya, e netefatsa ho holisoa ho nepahetseng ntle le ho sotha.

Likopo:

1. Khomphutha ya Quantum: Di-amplifier tsa lerata le tlase tsa Millimeter wave cryogenic tse sebediswang ho di-processor tsa quantum tse tsamaisang matla a ho fetisa ho matlafatsa matshwao a fokolang a ho bala a tswang ho qubits, ho nolofalletsa ho lekanya ka nepo maemo a quantum. Di kopantswe ka di-dilutionrefrigerators ho sebetsa mochesong wa millikelvin.
2. Bolepi ba Dinaledi ba Radio: E sebediswa ho di-teleskoupo tsa radio tse amohelang di-cryogenic ho hodisa matshwao a fokolang a tswang dinthong tse hole tsa lehodimo, ho ntlafatsa kutlwisiso le qeto ya ditemogo tsa bolepi ba dinaledi.
3. Lisebelisoa tsa Elektroniki tse tsamaisang motlakase o mongata: li-amplifier tsa lerata le tlaase tsa mm wave cryogenic tse sebelisoang lipotolohong tsa superconducting le li-sensor ho matlafatsa matšoao a fokolang ha ka nako e ts'oanang li boloka maemo a lerata a tlase, ho netefatsa ts'ebetso le tekanyo e nepahetseng ea matšoao.
4. Liteko tsa Mocheso o Tlase: E sebelisoa litlhophisong tsa lipatlisiso tsa cryogenic, joalo ka lithuto tsa superconductivity, quantum phenomena, kapa ho lemoha taba e lefifi, ho eketsa matšoao a fokolang ka lerata le fokolang.
5. Setšoantšo sa Bongaka: Se sebelisoa lits'ebetsong tse tsoetseng pele tsa ho nka litšoantšo joalo ka MRI (Magnetic Resonance Imaging) tse sebetsang mochesong oa cryogenic ho ntlafatsa boleng ba lets'oao le qeto.
6. Puisano ea Sebaka le Sathelaete: E sebelisoa litsamaisong tsa ho pholisa tse nang le cryogenic tsa lisebelisoa tse thehiloeng sebakeng ho matlafatsa matšoao a fokolang a tsoang sebakeng se tebileng, ho ntlafatsa bokhoni ba puisano le boleng ba data.
7. Fisiks ea Likaroloana: E sebelisoa ho li-detector tsa cryogenic bakeng sa liteko tse kang ho lemoha neutrino kapa lipatlisiso tsa lintho tse lefifi, moo ho eketsa lerata le tlase haholo ho leng bohlokoa.

Qualwavee fana ka Li-Amplifiers tsa Lerata le Tlase la Cryogenic ho tloha ho DC ho isa ho 8GHz, 'me mocheso oa lerata o ka ba tlase ho fihlela ho 10K.
