Makina a X-ray a Cold-cathode atha kusokoneza msika wamaganizidwe azachipatala

Makina a Cold cathode X-ray ali ndi kuthekera kosintha ukadaulo wa X-ray chubu, potero amasokoneza msika woyerekeza zamankhwala.Machubu a X-ray ndi gawo lofunikira la zida zojambulira zamankhwala, zomwe zimagwiritsidwa ntchito popanga ma X-ray ofunikira kuti apange zithunzi zowunikira.Ukadaulo wapano umadalira ma cathode otentha, koma makina ozizira a cathode amayimira kusintha kwamasewera m'munda uno.

ZachikhalidweX-ray machubu imagwira ntchito potenthetsa ulusi mpaka kutentha kwambiri, komwe kenaka kumatulutsa ma elekitironi.Ma elekitironiwa amafulumizitsidwa kupita ku chandamale, chomwe nthawi zambiri chimapangidwa ndi tungsten, ndikupanga ma X-ray akakhudzidwa.Komabe, njirayi ili ndi zovuta zingapo.Kutentha kwakukulu komwe kumafunika kutulutsa ma elekitironi kumachepetsa moyo wa machubu, chifukwa kutentha kosalekeza ndi kuzizira kumayambitsa kupsinjika kwa kutentha ndi kuwonongeka.Kuonjezera apo, kutenthetsa kumapangitsa kuti zikhale zovuta kutsegula ndi kuzimitsa chubu cha X-ray, ndikuwonjezera nthawi yofunikira pa kujambula.

Mosiyana ndi izi, makina ozizira a X-ray a cathode amagwiritsa ntchito gwero la ma elekitironi ndipo safuna kutenthetsa.M'malo mwake, makinawa amapanga ma elekitironi pogwiritsa ntchito gawo lamagetsi kunsonga yakuthwa kwa cathode, zomwe zimapangitsa kuti ma elekitironi atuluke chifukwa cha quantum tunneling.Popeza cathode sichitenthedwa, nthawi ya moyo wa chubu ya X-ray imakulitsidwa kwambiri, kupereka ndalama zomwe zingatheke kupulumutsa zipatala.

Kuphatikiza apo, makina ozizira a cathode X-ray amapereka maubwino ena.Iwo akhoza kutsegulidwa ndi kutsekedwa mwamsanga, kulola kuti chithunzithunzi chikhale chokwanira.Machubu ochiritsira a X-ray amafunikira nthawi yotentha mukayatsa, zomwe zitha kutenga nthawi pakagwa mwadzidzidzi.Ndi makina ozizira a cathode, kujambula kumatheka nthawi yomweyo, zomwe zingathe kupulumutsa nthawi yamtengo wapatali muzochitika zovuta zachipatala.

Kuonjezera apo, popeza palibe filament yotentha, palibe njira yoziziritsira yomwe imafunika, kuchepetsa zovuta ndi kukula kwa zipangizo za X-ray.Izi zingapangitse kuti pakhale zipangizo zamakono zogwiritsira ntchito komanso zowonongeka, zomwe zimapangitsa kuti kujambula kwachipatala kukhala kosavuta komanso kosavuta m'malo osiyanasiyana, kuphatikizapo malo akutali kapena zipatala zam'manja.

Ngakhale pali kuthekera kwakukulu kwa makina ozizira a cathode X-ray, pali zovuta zina zomwe ziyenera kuthetsedwa.Malangizo a cathode a m'munda ndi osalimba, owonongeka mosavuta, ndipo amafunikira kusamalidwa ndi kusamala.Kuphatikiza apo, njira yopangira ma quantum tunneling imatha kupanga ma elekitironi opanda mphamvu zochepa, zomwe zingayambitse phokoso lazithunzi ndikuchepetsa mawonekedwe onse azithunzi za X-ray.Komabe, kafukufuku wopitilira komanso kupita patsogolo kwaukadaulo kumafuna kuthana ndi zolephera izi ndikupereka njira zothetsera kufalikira kwa makina a X-ray ozizira a cathode.

Msika woyerekeza zamankhwala ndiwopikisana kwambiri komanso ukusintha mosalekeza, ndikupita patsogolo kwaukadaulo komwe kukuyendetsa bwino pakuzindikira komanso kuchiza.Makina a Cold cathode X-ray amatha kusokoneza msikawu ndi zabwino zambiri kuposa ukadaulo wamakono wa X-ray chubu.Kutalikitsa moyo, kusintha mwachangu komanso kuchepa kwa kukula kumatha kusintha malingaliro azachipatala, kupititsa patsogolo chisamaliro cha odwala ndikuwonjezera magwiridwe antchito achilengedwe chonse.

Pomaliza, makina ozizira a cathode X-ray akuyimira zatsopano zomwe zitha kusokoneza msika wamaganizidwe azachipatala.Posintha umisiri wotentha wa filament wachikhalidweX-ray machubu, machitidwewa amapereka moyo wautali, kusinthasintha mofulumira, komanso kuthekera kwa zipangizo zambiri zonyamula.Ngakhale kuti zovuta zikuyenera kuthetsedwa, kufufuza kosalekeza kumafuna kuthana ndi zofookazi ndikupanga makina ozizira a cathode X-ray kukhala muzojambula zachipatala, kukonza chisamaliro cha odwala ndi kusintha makampani.
