Cold cathode X-ray masisitimu ane mukana wekushandura X-ray chubhu tekinoroji, nekudaro kukanganisa musika wekufungidzira wekurapa. X-ray machubhu chikamu chakakosha chemidziyo yekufungidzira yekurapa, inoshandiswa kugadzira max-ray anodiwa kugadzira mifananidzo yekuongorora. Tekinoroji yazvino inotsamira pamakathodhi anopisa, asi inotonhora-cathode masisitimu inomiririra inogona kuchinja mutambo mundima iyi.
TraditionalX-ray tubes shanda nekudziisa filament kune tembiricha yepamusoro, iyo inobva yaburitsa maerekitironi. Aya maerekitironi anokwidziridzwa akananga kune chinangwa, kazhinji anogadzirwa netungsten, achigadzira X-rays pakubata. Zvisinei, nzira iyi ine zvipingamupinyi zvakawanda. Tembiricha yepamusoro inodiwa pakuburitsa maerekitironi inodzikamisa hupenyu hwemachubhu, sezvo kugara uchidziya nekutonhodza kuchikonzera kushushikana kwekupisa nekudzikira. Uyezve, iyo yekudziya inoita kuti zviome kukurumidza kushandura X-ray chubhu uye kudzima, kuwedzera nguva inodiwa yekufungidzira maitiro.
Mukupesana, inotonhora cathode X-ray masisitimu anoshandisa munda emission electron sosi uye haidi kudziyisa. Pane kudaro, masisitimu aya anoburitsa maerekitironi nekuisa munda wemagetsi kune yakapinza cathode tip, zvichikonzera kubuda kweelectron nekuda kwequantum tunneling. Sezvo iyo cathode isingadziyirwe, hupenyu hwe X-ray chubhu hunowedzera zvakanyanya, zvichipa mari inogona kuchengetedza nzvimbo dzekurapa.
Mukuwedzera, inotonhora cathode X-ray systems inopa mamwe mabhenefiti. Vanogona kuvhurwa uye kuvharwa nekukurumidza, zvichibvumira kuti pave nekuita kwekufungidzira kunoshanda. Yakajairwa X-ray machubhu inoda nguva yekudziya-mushure mekuchinja, izvo zvinogona kutora nguva-nguva mumamiriro ekukurumidzira. Nekutonhora kwecathode system, kufungidzira kunogoneka nekukurumidza, zvichigona kuchengetedza nguva yakakosha mumamiriro ekurapa akakosha.
Uyezve, sezvo pasina filament inopisa, hapana kutonhora kunodiwa, kuderedza kuoma uye ukuru hwemichina yeX-ray. Izvi zvinogona kutungamirira kukugadzirwa kwezvimwe zvinotakurika uye zvigadziriswe zvekufungidzira zvigadziriswe, zvichiita kuti kufungidzira kwezvokurapa kuve nyore uye nyore mumamiriro akasiyana-siyana, kusanganisira nzvimbo dziri kure kana nzvimbo dzekurapa dzinofamba.
Pasinei nekukwanisa kukuru kwekutonhora cathode X-ray systems, kuchine mamwe matambudziko anoda kugadziriswa. Mazano emumunda emission cathode haana kusimba, ari nyore kukuvadzwa, uye anoda kungwarira kubata nekugadzirisa. Pamusoro pezvo, iyo quantum tunneling process inogona kugadzira yakaderera-simba maerekitironi, ayo anogona kukonzera ruzha rwemifananidzo uye kuderedza huwandu hwese hwemifananidzo yeX-ray. Nekudaro, kuenderera mberi kwekutsvagisa uye kufambira mberi kwetekinoroji kunovavarira kukunda zvipingamupinyi izvi uye nekupa mhinduro dzekuitwa kwakapararira kweinotonhora-cathode X-ray masisitimu.
Musika wekufungidzira wekurapa unokwikwidza zvakanyanya uye unogara uchibuda, nekufambira mberi kwetekinoroji inofambisa kuvandudzwa mukuongororwa uye kurapwa. Cold cathode X-ray masisitimu ane mukana wekukanganisa musika uyu neakakosha mabhenefiti pamusoro pechinyakare X-ray chubhu tekinoroji. Kuwedzerwa hupenyu, kukurumidza kuchinja uye kuderedzwa saizi kunogona kushandura kufungidzira kwekurapa, kuwedzera kutarisirwa kwevarwere uye kuwedzera kushanda kwese kwenzvimbo yehutano.
Mukupedzisa, inotonhora cathode X-ray masisitimu inomiririra inovimbisa hunyanzvi iyo inogona kukanganisa musika wekufungidzira wekurapa. Nekutsiva iyo inopisa filament tekinoroji yechinyakareX-ray tubes, masisitimu aya anopa hupenyu hwakareba, kugona kukurumidza kushandura, uye kugona kwezvimwe zvinotakurika zvishandiso. Kunyange zvipingamupinyi zvichisara kugadziriswa, tsvakiridzo inoenderera ine chinangwa chekukunda zvipimo izvi uye kuita inotonhora cathode X-ray masisitimu ive yakajairwa mukufungidzira kwekurapa, kuvandudza kutarisirwa kwevarwere uye kushandura indasitiri.
