Menene bututun x-ray?

Bututun X-ray sune diodes na injin da ke aiki a babban ƙarfin lantarki.
Bututun X-ray ya ƙunshi electrodes guda biyu, anode da cathode, waɗanda ake amfani da su don a yi amfani da electrons da za a yi amfani da su wajen haɗa su da juna, sannan a yi amfani da filament don fitar da electrons, bi da bi. An rufe sandunan biyu a cikin babban gilashin ko rufin yumbu.

Sashen samar da wutar lantarki na bututun X-ray yana ɗauke da aƙalla wutar lantarki mai ƙarancin ƙarfi don dumama filament da kuma janareta mai ƙarfin lantarki don amfani da babban ƙarfin lantarki a kan sandunan biyu. Lokacin da wayar tungsten ta wuce isasshen wutar lantarki don ƙirƙirar girgijen electron, kuma aka sanya isasshen ƙarfin lantarki (bisa ga tsarin kilovolts) tsakanin anode da cathode, ana ja gajimaren electron zuwa ga anode. A wannan lokacin, electrons sun bugi maƙasudin tungsten a cikin yanayi mai ƙarfi da sauri. Elektrons masu saurin gudu suna isa saman abin da ake nufi, kuma motsinsu ba zato ba tsammani ya toshe. Wani ƙaramin ɓangare na kuzarin motsi na su yana canzawa zuwa makamashin radiation kuma an sake shi a cikin nau'in X-ray. Ana kiran hasken da aka samar a cikin wannan tsari don bremsstrahlung.

Canza wutar lantarki ta filament na iya canza zafin filament da adadin electrons da ake fitarwa, ta haka ne za a canza wutar lantarki ta bututu da kuma ƙarfin hasken X-ray. Canza ƙarfin motsawar bututun X-ray ko zaɓar wani manufa daban na iya canza kuzarin hasken X-ray ko ƙarfin kuzari daban-daban. Saboda fashewar electrons masu ƙarfi, bututun X-ray yana aiki a babban zafin jiki, wanda ke buƙatar tilasta sanyaya abin da anode ke nufi.

Duk da cewa ingancin makamashin bututun X-ray don samar da X-ray yana da ƙasa sosai, a halin yanzu, bututun X-ray har yanzu sune na'urorin samar da X-ray mafi amfani kuma ana amfani da su sosai a cikin kayan aikin X-ray. A halin yanzu, aikace-aikacen likita galibi an raba su zuwa bututun X-ray na gano cututtuka da bututun X-ray na warkewa.
