Chii chinonzi x-ray chubhu?

X-ray machubhu ivacuum diode inoshanda pamagetsi akakwira.
Tubhu yeX-ray ine maelectrodes maviri, anode uye cathode, ayo anoshandiswa kuti chinangwa chibhombwe nemaerekitironi uye filament kuti ibudise maerekitironi, zvichiteerana. Matanda ese ari maviri akavharirwa mune yakakwira vacuum girazi kana ceramic dzimba.

Chikamu chekupa magetsi che X-ray chubhu ine kanenge yakaderera voltage magetsi ekudziya filament uye yakakwira voltage jenareta yekushandisa yakakwira voltage kumatanda maviri. Kana waya ye tungsten inopfuura yakakwana ikozvino kuti igadzire gore re electron, uye simba rakakwana (pahurongwa hwe kilovolts) rinoshandiswa pakati pe anode ne cathode, gore re electron rinodhonzwa rakananga kunode. Panguva ino, maerekitironi anorova tungsten chinangwa mune yakakwirira-simba uye yakakwirira-kumhanya mamiriro. Maerekitironi anomhanya-mhanya anosvika panzvimbo yaanonangwa, uye kufamba kwawo kunongoerekana kwavharwa. Chikamu chidiki chesimba ravo rekinetic chinoshandurwa kuita simba remwaranzi uye kuburitswa muchimiro cheX-rays. Mwaranzi inogadzirwa mune iyi fomu inonzi bremsstrahlung.

Kushandura filament ikozvino kunogona kushandura tembiricha yefilament uye huwandu hwemaerekitironi anoburitswa, nekudaro kuchinja chubhu ikozvino uye kusimba kweX-rays. Kusandura kugona kwekunakidzwa kweX-ray chubhu kana kusarudza imwe chinangwa kunogona kushandura simba rechiitiko X-ray kana kusimba pamasimba akasiyana. Nekuda kwekubhomba kwemaerekitironi ane simba guru, chubhu yeX-ray inoshanda pakupisa kwakanyanya, izvo zvinoda kutonhodzwa kwekumanikidzwa kweanode target.

Kunyange zvazvo simba remachubhu eX-ray kugadzira maX-rays rakaderera zvikuru, pari zvino, machubhu eX-ray achiri midziyo yekugadzira X-ray inonyanya kushandiswa uye ave achishandiswa zvakanyanya mumidziyo yeX-ray. Parizvino, mishonga yekurapa inonyanya kukamurwa kuva diagnostic X-ray chubhu uye kurapa X-ray chubhu.
