Magnetron: tallaabo oo mabda 'ka mid ah qalabka

Si aad u hesho gariirka gaarka loo leeyahay iyo sare, isticmaali magnetrons. beeraha Electric iyo magnetic waafaqsanayn awood sare. Sidaas darteed, gariirka ee hirka sare dhacaan. nooc si joogto ah loo isticmaalo qalabka waa Multiresonator. fal magnetron Tani on electrons kaliya seddex beeraha:

• korontada,
• magnetic;
• Microwave.

Magnetron: waxaa u muuqday iyo sida

Waayo, markii ugu horeysay ee xilli ciyaareedkan ayaa waxaa loo isticmaalaa in 1921 by jirka A. Hull Maraykanka. Waxa uu cilmi baaris iyo tijaabooyin ayaa sii, taasoo keentay in soo bixitaanka of noocyo badan oo magnetrons, oo waxay bilaabeen inay in la isticmaalo ee korantada. patent ee la alifay this helay by Jacquet ee 1924. Waxa uu ahaa kii been abuurtay magnetron casriga ah, kuwaas oo mabda 'hawlgalka ku salaysan yahay is dhexgalka laba beeraha.

Tobankii sano ee soo socda ayaa lagu soo koraya magnetron in ay curiyaan microwaves. Ujeedada ugu weyn wuxuu ahaa in la kordhiyo inta jeer oscillation, kaas oo la samayn karaa oo keliya by cilmiga Soofiyeeti. Oo waxay ku kordheen qiimaha bilowga ah laba jeer, iyadoo la isticmaalayo copper sida wax anode ah.

qalab

Heart block anode magnetron ka kooban yahay dhululubo copper leh dalool ah gudaha ah. At ay xarunta, waxaa jira godadka, iyagu waa godadka nidaamka giraanta. In dhexe ee anode leeyahay god iyada oo ay tahay in ay ku xidhmaan korontada ah. Sidoo kale, anode waxaa ka mid ah waxaa ku xiran cathode ah. Isagu waa buuxieyey, waa kuleelka iyo maraa dhexe ee anode ah. Si loo xaqiijiyo in wax soo saarka sare saarka oscillation ayaa lagu wadaa in resonator noocan oo kale ah. Inside vacuum ee block anode ah. Wixii fin qaboojinta ayaa lagu wadaa dushiisa diiriya.

Dhig unit si uu dhexda u magnet-ka abuuraan beer magnetic of xoog ku filan. In la dhiso danab ka dhexeeya ee anode iyo cathode ah, iyo si terminal wanaagsan eedeeyay waxa uu ku yaalaa meel u dhow anode ah. electrons ka cathode waxay bilaabayaan in ay u guuraan ay sabab u tahay tallaabada duurka oo koronto ah. Waa in ay u anode iyo magnetron ah, mabda'a ah ficil taas oo guurto beer magnetic, waxaa masaal Laabtay cathode ah.

Si loo gaaro saamaynta, marka electrons ka guuraan oo ay la socdaan goobada ku tilmaamay oo sidaas waa ku xiga si ay anode ah, laakiin waxaa ku soo laabtay, waxaa suurto gal ah, si ay u dhawraan haddii shuruudaha qaarkood in laba beeraha la xidhiidha. In gobolka this, anode waa kaliya jajab yar oo dhan electrons ka cathode ka timaada.

Ku soo noqoshada cathode ee electrons la bedelay. Nidaamkan wuxuu soconayaa, la xirrira dhow anode ka mas'uul ah ee foomka of siddo. amar caynkaas bilaabaa inuu la aasaasay at dalool kasta, waxaa jira gariirka ee hirka sare undamped. isbedbedelka noocan oo kale ah ka bixi karo gariiradda of silig ka dhigeen, iyaga diyaarinaysaa in mid ka mid ah godadka ah. Ka dib markii vibrations waxyaalahan waxaa loo kala qaado si waveguide (ama line coaxial).

Magnetron waxaa loo yeedhi karaa qalab microwave, waxa matoor, vacuum ah, mooshinka ee electrons in ay qaadanayso meel laba beeraha, electronic iyo magnetic. Waxay abuurtaa mabda'a magnetron hawlgalka ka mid ah laba beeraha, taas oo samaysa saddexaad a - microwave ah.
