Magnetron

Sebopeho sa Sebopeho

Sistimi ea Cathode le Anode

Likarolo tsa mantlha tsa magnetron ke cathode le anode. Hangata cathode ke cathode e chesang, e ntšang li-electrone ha e futhumala. Li-electrone tsena li potlakisoa ke tšimo ea motlakase pakeng tsa cathode le anode 'me li qala ho tsamaea. Anode ke sebopeho se rarahaneng se nang le likoti tse ngata tse resonant. Li-cavities tsena ke libaka tsa bohlokoa bakeng sa ho hlahisa matla a microwave, 'me boholo ba tsona le sebōpeho li ama makhetlo le matla a li-microwave.

Mohlala, ka har'a magnetron ea ontong ea microwave e tloaelehileng, likhaba tsa anode resonant li etselitsoe hantle ho hlahisa maqhubu a microwave a ka bang 2450 MHz. Khafetsa ena e etsa hore limolek'hule tsa polar tse kang limolek'hule tsa metsi li thothomele ka maqhubu a phahameng, kahoo li futhumatsa lijo.

Magnetic Field System

Matla a khoheli ke ntho ea bohlokoa bakeng sa ts'ebetso e tloaelehileng ea magnetron. Matla a khoheli a hlahisoa ke limakete tse sa feleng kapa li-electromagnets. Ha magnetron e sebetsa, tataiso ea matla a khoheli e pota-potile ka lehlakoreng la tlhahiso ea elektronike. Li-electrone li tsamaea ka mokhoa oa ho potoloha tlas'a tšusumetso ea matla a khoheli, e leng se nolofalletsang ho sebelisana pakeng tsa li-electrone le li-cavities tse resonant, ka tsela eo li thabisa likoti ho hlahisa li-microwaves.

Ka mohlala, ho li-magnetron tse matla a phahameng a indasteri, matla a khoheli a matla a ka laola ka nepo tsela eo motsamao oa elektrone o tsamaeang ka eona, ho netefatsa tšebelisano e ntle pakeng tsa lielektrone le likheo tsa resonant. Sena se fella ka tlhahiso ea li-microwave tse matla a phahameng bakeng sa lits'ebetso tsa indasteri joalo ka ho futhumatsa le ho omisa ka microwave.

Molao-motheo oa ho Sebetsa

Phallo ea Elektrone le Motion oa Pele

Ha cathode e futhumetse mocheso o itseng, e qala ho ntša lielektrone. Li-electrone tsena li potlakisoa ke tšimo ea motlakase pakeng tsa cathode le anode 'me li fallela ho anode. Ka nako e ts'oanang, ka lebaka la ho ba teng ha matla a khoheli, li-electrone li khelosoa ke matla a Lorentz nakong ea ho tsamaea ha tsona.

Ho utloisisa sena habonolo, nahana hore lielektrone li ne li tla tsamaea ka tsela e otlolohileng tšimong ea motlakase. Leha ho le joalo, matla a khoheli a sebetsa e le “tataiso,” a etsa hore tselana ea lielektrone e kobehe hore e tsamaee e bilika.

Mokhoa oa ho hlahisa microwave

Ha lielektrone li ntse li tsamaea pakeng tsa li-anode resonant cavities, li tsoela pele ho sebelisana le sebaka sa motlakase sa likoti. Matla a ho sisinyeha ha lielektrone a fetisetsoa mekoting, e leng se etsang hore matla a matla a motlakase a ka har'a likoti a eketsehe a sa khaotse, 'me a qetelle a theha microwave oscillation e tsitsitseng.

Li-cavities tse resonant li sebetsa joaloka "amplifier ea matla." Matla a ho sisinyeha ha lielektrone a bokellana ka har'a likoti. Ha maemo a itseng a finyelloa, li-microwave li hlahisoa 'me li hlahisoa ho tsoa pheletsong ea magnetron (hangata khokahano ea waveguide). Li-microwaves tsena li sebelisoa lits'ebetsong tse fapaneng.

Libaka tsa Kopo

Lisebelisoa tsa Lehae - Lionto tsa Microwave

Magnetron ke karolo ea bohlokoa ea lionto tsa microwave. E hlahisa li-microwave tse ka futhumatsang lijo kapele. Li-microwave tse hlahisoang ke magnetron ka ontong ea microwave hangata li na le maqhubu a 2450 MHz. Khafetsa ena ea li-microwave e ka etsa hore limolek'hule tsa polar tse kang metsi le limolek'hule tsa mafura tse ka har'a lijo li thothomele ka maqhubu a phahameng. Khohlano e teng pakeng tsa limolek'hule e hlahisa mocheso, kahoo e fumana ho futhumatsa ka potlako.

Ka mohlala, ho futhumatsa kopi ea lebese ho nka metsotso e seng mekae feela, 'me lebese le ka fihla mocheso o loketseng oa ho noa. Ho feta moo, lionto tsa microwave hangata li futhumatsa lijo ka ho lekana, li fana ka mokhoa o bonolo le o potlakileng oa ho fihlela litlhoko tsa batho tsa letsatsi le letsatsi bakeng sa ho futhumatsa lijo.

Lisebelisoa tsa indasteri

Ho futhumatsa le ho Omisa ka Microwave: Tlhahisong ea indasteri, li-microwave tse hlahisoang ke magnetron li ka sebelisoa ho futhumatsa le ho omisa lisebelisoa tse fapaneng. Mohlala, indastering ea ho lokisa lehong, ho omisoa ha patsi ka microwave ho ka fokotsa haholo nako ea ho omisa, ho ntlafatsa ts'ebetso ea tlhahiso, le ho fokotsa deformation le ho peperana ha patsi nakong ea ho omisa. Bakeng sa ho omisa lisebelisoa tse tala tsa lik'hemik'hale, ho futhumala ha microwave ho ka finyella liphello tse omisang ka potlako le tse tšoanang, ho ntlafatsa boleng ba sehlahisoa.

Puisano ea Microwave: Lits'ebetsong tsa pele tsa puisano tsa microwave, li-magnetron le tsona li bile le karolo. Li ka sebetsa e le mehloli ea matšoao a microwave, 'me matšoao a microwave a fetisetsoa pheletsong e amohelang ka li-waveguides le lisebelisoa tse ling tsa phetisetso ho fihlela puisano e hole. Leha ho le joalo, ka nts'etsopele ea theknoloji ea semiconductor le mafapha a mang, mefuta e meng ea mehloli ea microwave e se e sebelisoa haholo puisanong ea microwave.

Sistimi ea Radar

Li-magnete li ka sebelisoa hape e le mehloli ea microwave lits'ebetsong tse ling tse bonolo tsa radar. Li ka hlahisa li-pulse tsa microwave tse matla haholo, tse hlahisoang ke li-antenna. Ha li-pulse tsena li kopana le lintho tse shebiloeng, li bonahatsoa morao. Sistimi e amohelang radar e bona mats'oao a microwave a bonts'itsoeng ho tseba boemo, lebelo le tlhaiso-leseling e 'ngoe ea lintho tse shebiloeng.

Mohlala, litsing tse ling tse nyane tsa radar ea boemo ba leholimo kapa lisebelisoa tsa radar tsa nako e khuts'oane, li-magnetron li ka fana ka matla a lekaneng a microwave ho fihlela mesebetsi ea ho lemoha sepheo.
