Makina a X-ray ozizira amatha kusokoneza msika wa zithunzi zachipatala

Makina a X-ray a cathode yozizira ali ndi kuthekera kosintha ukadaulo wa chubu cha X-ray, motero kusokoneza msika wa kujambula zamankhwala. Machubu a X-ray ndi gawo lofunikira la zida zojambulira zamankhwala, zomwe zimagwiritsidwa ntchito popanga ma x-ray ofunikira popanga zithunzi zowunikira. Ukadaulo wamakono umadalira ma cathode otentha, koma makina a cold-cathode ndi omwe angasinthe kwambiri nkhaniyi.

ZachikhalidweMachubu a X-ray ntchito potenthetsa ulusi kufika kutentha kwakukulu, komwe kumatulutsa ma elekitironi. Ma elekitironi amenewa amafulumizitsidwa kupita ku cholinga, nthawi zambiri amapangidwa ndi tungsten, ndikupanga ma X-ray akagunda. Komabe, njirayi ili ndi zovuta zingapo. Kutentha kwakukulu komwe kumafunika kuti ma elekitironi atuluke kumachepetsa moyo wa machubu, chifukwa kutentha ndi kuzizira kosalekeza kumayambitsa kupsinjika kwa kutentha ndi kuwonongeka. Kuphatikiza apo, njira yotenthetsera imapangitsa kuti zikhale zovuta kuyatsa ndi kuzimitsa chubu cha X-ray mwachangu, zomwe zimawonjezera nthawi yomwe imafunika kuti chithunzicho chichitike.

Mosiyana ndi zimenezi, makina ozizira a X-ray a cathode amagwiritsa ntchito magwero a ma elekitironi otulutsa mpweya m'munda ndipo safuna kutentha. M'malo mwake, makinawa amapanga ma elekitironi mwa kugwiritsa ntchito mphamvu yamagetsi ku nsonga yakuthwa ya cathode, zomwe zimapangitsa kuti ma elekitironi atuluke chifukwa cha kutsetsereka kwa quantum tunneling. Popeza cathode sitenthedwa, nthawi ya moyo wa chubu cha X-ray imakulitsidwa kwambiri, zomwe zimapangitsa kuti zipatala zisawononge ndalama.

Kuphatikiza apo, makina a X-ray ozizira amapereka zabwino zina. Amatha kutsegulidwa ndi kutsekedwa mwachangu, zomwe zimapangitsa kuti njira yojambulira zithunzi ikhale yogwira mtima kwambiri. Machubu a X-ray wamba amafunika nthawi yotenthetsera thupi mukayamba kuyatsa, zomwe zingatenge nthawi yayitali pakagwa ngozi. Ndi makina a X-ray ozizira, kujambula zithunzi kumatha kuchitika nthawi yomweyo, zomwe zingapulumutse nthawi yamtengo wapatali pazochitika zofunika kwambiri zachipatala.

Kuphatikiza apo, popeza palibe ulusi wotenthedwa, palibe njira yoziziritsira yomwe imafunika, zomwe zimachepetsa zovuta ndi kukula kwa zida za X-ray. Izi zingayambitse kupanga zida zonyamulika komanso zazing'ono zojambula zithunzi, zomwe zimapangitsa kuti kujambula zithunzi zachipatala kukhale kosavuta komanso kosavuta m'malo osiyanasiyana, kuphatikizapo malo akutali kapena zipatala zoyenda.

Ngakhale kuti makina a X-ray ozizira a cathode ali ndi mphamvu zambiri, palinso mavuto ena omwe akufunika kuthana nawo. Nsonga za cathode zotulutsa mpweya m'munda ndi zofooka, zimawonongeka mosavuta, ndipo zimafunika kusamalidwa mosamala. Kuphatikiza apo, njira yopangira ma quantum tunneling ingapangitse ma elekitironi opanda mphamvu zambiri, zomwe zingayambitse phokoso la zithunzi ndikuchepetsa mtundu wonse wa zithunzi za X-ray. Komabe, kafukufuku wopitilira ndi kupita patsogolo kwaukadaulo cholinga chake ndi kuthana ndi zofooka izi ndikupereka mayankho pakukhazikitsa machitidwe a X-ray ozizira.

Msika wa kujambula zithunzi zachipatala ndi wopikisana kwambiri ndipo ukusintha nthawi zonse, ndi kupita patsogolo kwaukadaulo komwe kukupangitsa kuti matenda ndi chithandizo zipite patsogolo. Makina a X-ray ozizira amatha kusokoneza msikawu ndi zabwino zambiri kuposa ukadaulo wamakono wa X-ray. Moyo wautali, kusintha mwachangu komanso kukula kochepa kumatha kusintha zithunzi zachipatala, kukulitsa chisamaliro cha odwala ndikuwonjezera magwiridwe antchito onse azaumoyo.

Pomaliza, makina ozizira a X-ray a cathode akuyimira luso latsopano lomwe lingasokoneze msika wa kujambula zithunzi zachipatala. Mwa kusintha ukadaulo wotentha wa filament wachikhalidweMachubu a X-ray, makinawa amapereka moyo wautali, mphamvu zosinthira mwachangu, komanso kuthekera kwa zipangizo zina zonyamulika. Ngakhale kuti mavuto akadalipo, kafukufuku wopitilira akufuna kuthana ndi zofooka izi ndikupanga makina ozizira a X-ray kukhala muyezo wojambulira zithunzi zachipatala, kukonza chisamaliro cha odwala komanso kusintha makampani.
