Kupatsanurwa kweMachubhu eX-ray
Zvichienderana nenzira yekugadzira maerekitironi, machubhu eX-ray anogona kukamurwa kuita machubhu ane gasi uye machubhu evacuum.
Zvichienderana nezvinhu zvakasiyana-siyana zvekuvhara, inogona kukamurwa kuita chubhu yegirazi, chubhu yeceramic uye chubhu yesimbi yeceramic.
Zvichienderana nemashandisirwo akasiyana, inogona kukamurwa kuita machubhu eX-ray ekurapa uye machubhu eX-ray eindasitiri.
Zvichienderana nenzira dzakasiyana dzekuvhara, inogona kukamurwa kuita machubhu eX-ray akavhurika uye machubhu eX-ray akavharika. Machubhu eX-ray akavhurika anoda vacuum inogara iripo panguva yekushandiswa. Chubhu yeX-ray yakavharika inovharwa pakarepo mushure mekubvisa vacuum kusvika pamwero wakati wekugadzirwa kwechubhu yeX-ray, uye hapana chikonzero chekubvisa vacuum zvakare panguva yekushandiswa.
Machubhu eX-ray anoshandiswa mukurapa kuongorora nekurapa, uye muhunyanzvi hwemaindasitiri pakuedza zvinhu zvisingaparadze, kuongorora chimiro, kuongorora spectroscopic uye kuona firimu. Machubhu eX-ray anokuvadza muviri wemunhu, uye matanho ekudzivirira anoshanda anofanira kutorwa pakushandisa.
Maumbirwo echubhu yeX-ray yeanode yakagadziriswa
Chubhu yeX-ray inogadziriswa yeanode ndiyo mhando iri nyore yechubhu yeX-ray inoshandiswa zvakanyanya.
Anode iyi ine musoro weanode, chivharo cheanode, mhete yegirazi uye mubato weanode. Basa guru reanode nderekuvhara kufamba kwemaerekitironi anofamba nekukurumidza nepamusoro pemusoro weanode (kazhinji kacho tungsten target) kuti igadzire maX-ray, uye kuburitsa kupisa kunobva kwaitika kana kuifambisa nepamubato weanode, uye zvakare kutora maerekitironi echipiri nemaerekitironi akapararira. Misi.
X-ray inogadzirwa nechubhu yeX-ray ine tungsten alloy inoshandisa simba risingasviki 1% chete remagetsi ekufambisa maerekitironi anofamba nekukurumidza, saka kupisa inyaya yakakosha kwazvo pachubhu yeX-ray. Cathode inonyanya kuumbwa nefilament, focusing mask (kana inonzi cathode head), cathode sleeve uye girazi stem. Beam remaerekitironi rinoputira anode target rinoburitswa nefilament (kazhinji tungsten filament) yehot cathode, uye rinoumbwa nefocusing nefocusing mask (cathode head) pasi pekukwira kwevoltage yechubhu yeX-ray ine tungsten alloy. Beam remaerekitironi rinofamba nekukurumidza rinorova anode target uye rinongoerekana ravharwa, izvo zvinogadzira chikamu cheX-ray chine simba rinoenderera mberi (kusanganisira maX-ray anoratidza anode target metal).
