Ithini i-X-ray tube?

Amashubhu we-X-ray angama-vacuum diodes asebenza ngama-voltages aphezulu.
I-X-ray tube iqukethe ama-elektrode amabili, i-anode ne-cathode, esetshenziselwa ilitshe ukuthi lihlaselwe ngama-elektroni kanye ne-filament ukuze ukhiphe ama-elektroni, ngokulandelana. Zombili lezi zigxobo zibekwa uphawu ku-vacuum glass ephezulu noma izindlu ze-ceramic.

Isigaba Sokuhlinzekwa Kwamandla se-X-ray tube siqukethe okungenani amandla kagesi aphansi wokushisa i-filament kanye ne-generator ephezulu ye-voltage ukusebenzisa i-voltage ephezulu ezigxotsheni ezimbili. Lapho ucingo lwe-tungsten ludlula lwamanje lwamanje ukudala i-elektroni, kanye ne-voltage eyanele (ngokulandelana kwama-kilovolts) kusetshenziswa phakathi kwe-anode ne-cathode, ifu le-elektroni lidonswa ebheke ku-anode. Ngalesi sikhathi, ama-elektroni ashaya iTungsten Target ngesimo esiphakeme kanye nesivinini esiphakeme. Ama-elektroni ashesha kakhulu afinyelela endaweni eqondiwe, futhi ukunyakaza kwawo kuvinjelwe kungazelelwe. Ingxenye encane yamandla abo e-kinetic iguqulwa ibe amandla emisebe futhi ikhishwe ngendlela yama-x-ray. Imisebe ekhiqizwe kuleli fomu ibizwa ngeBremsstrahleng.

Ukushintsha indawo yamanje yamandla kungashintsha amazinga okushisa okufafazwa kanye nenani lama-elektroni akhishwe, ngaleyo ndlela aguqule ishubhu yamanje namandla ama-x-ray. Ukushintsha amandla okuvuselela amakhono we-X-ray tube noma ukhethe ilitshe elihlukile kungashintsha amandla wesigameko x-ray noma ubukhulu kumandla ahlukile. Ngenxa yokuqhuma kwamabhomu ama-elektroni aphezulu, ishubhu le-x-ray lisebenza ngokushisa okuphezulu, okudinga ukuphoqelelwa okuphoqelekile kwelitshe le-anode.

Yize ukusebenza kwamandla kwama-X-ray shubhu ukukhiqiza ama-X-ray kuphansi kakhulu, njengamanje, amashubhu we-X-ray asasebenza kakhulu ama-X-ray akhiqiza amadivaysi futhi asetshenziswe kabanzi kuma-X-ray amathuluzi. Njengamanje, izinhlelo zokusebenza zezokwelapha zihlukaniswe ikakhulu kumashubhu we-X-ray Diagnostic kanye namashubhu wezokwelapha we-X-ray.
