He aha ka ʻōmole x-ray?

ʻO nā ʻōmole X-ray he mau diode vacuum e hana ana ma nā voltages kiʻekiʻe.
ʻO kahi paipu X-ray he ʻelua mau electrodes, kahi anode a me kahi cathode, i hoʻohana ʻia no ka pahuhopu e hoʻopuehu ʻia me nā electrons a me ka filament e hoʻokuʻu i nā electrons. Hoʻopaʻa ʻia nā pou ʻelua i loko o ke aniani vacuum kiʻekiʻe a i ʻole nā ​​​​hale keramika.

Aia i loko o ka ʻāpana lako mana o ka paipu X-ray ma ka liʻiliʻi he lako mana haʻahaʻa haʻahaʻa no ka hoʻomehana ʻana i ka filament a me kahi mea hana uila kiʻekiʻe no ka hoʻopili ʻana i kahi uila kiʻekiʻe i nā pou ʻelua. Ke hala kahi uea tungsten i ke au e hana i kahi ao electron, a ua hoʻopili ʻia ka uila lawa (ma ke kauoha o kilovolts) ma waena o ka anode a me ka cathode, ua huki ʻia ke ao electron i ka anode. I kēia manawa, ua paʻi nā electrons i ka pahuhopu tungsten ma ke ʻano ikehu kiʻekiʻe a me ka wikiwiki kiʻekiʻe. Hiki nā electrons wikiwiki kiʻekiʻe i ka ʻili o ka pahuhopu, a ua ālai koke ʻia ko lākou neʻe ʻana. Hoʻololi ʻia kahi hapa liʻiliʻi o ko lākou ikehu kinetic i ikehu radiation a hoʻokuʻu ʻia ma ke ʻano o nā kukuna X. ʻO ka radiation i hana ʻia ma kēia ʻano ua kapa ʻia ʻo bremsstrahlung.

Hiki i ka hoʻololi ʻana i ke au filament ke hoʻololi i ka mahana o ke filament a me ka nui o nā electrons i hoʻokuʻu ʻia, no laila e hoʻololi ana i ke au o ka paipu a me ka ikaika o nā kukuna X. ʻO ka hoʻololi ʻana i ka hiki ke hoʻonāukiuki o ka paipu X-ray a i ʻole ke koho ʻana i kahi pahuhopu ʻokoʻa e hiki ke hoʻololi i ka ikehu o ka X-ray i hoʻokomo ʻia a i ʻole ka ikaika ma nā ikehu like ʻole. Ma muli o ka hoʻouka ʻia ʻana o nā electrons ikehu kiʻekiʻe, hana ka paipu X-ray ma kahi mahana kiʻekiʻe, kahi e pono ai ka hoʻomaʻalili ikaika o ka pahuhopu anode.

ʻOiai he haʻahaʻa loa ka pono o ka ikehu o nā ʻōmole X-ray e hana i nā kukuna X-ray, i kēia manawa, ʻo nā ʻōmole X-ray nā mea hana hana kukuna X-ray pono loa a ua hoʻohana nui ʻia i nā mea hana kukuna X-ray. I kēia manawa, ua māhele nui ʻia nā noi lapaʻau i nā ʻōmole X-ray diagnostic a me nā ʻōmole X-ray therapeutic.
