Sumo pfupi yeUltraviolet phototube:

Ultraviolet phototube imhando ye ultraviolet yekuona chubhu ine photoelectric effect. Mhando iyi yephotocell inoshandisa cathode kugadzira photoemission, maphotoelectrons anofamba akananga kune anode pasi pechiito chemunda wemagetsi, uye ionization inoitika nekuda kwekudhumhana nemaatomu egasi muchubhu panguva yeionization; maerekitironi matsva nemaphotoelectrons akaumbwa neiyo ionization process ese ari maviri anogamuchirwa neanode, nepo maioni akanaka anogamuchirwa necathode kune rimwe divi. Naizvozvo, iyo photocurrent muanode circuit yakakura kakawanda kupfuura iyo muvacuum phototube. Ultraviolet photocells ine simbi photovoltaic uye gasi yakawedzera mhedzisiro inogona kuona iyo ultraviolet mwaranzi muhuwandu hwe185-300mm uye kugadzira photocurrent.

Haina hanya nemwaranzi kunze kwenzvimbo ino inotaridzika, senge zuva rinooneka uye magetsi emukati. Saka hazvifanirwe kushandisa inooneka mwenje nhoo semimwe semiconductor zvishandiso, saka zviri nyore kushandisa.
Ultraviolet phototube inogona kuona isina simba ultraviolet mwaranzi. Inogona kushandiswa mu boiler mafuta emafuta, gasi yekutarisa, moto alarm, simba system yekudzivirira mheni yekutarisa isina kutariswa transformer, nezvimwe.
