Kettering Review-Equipment Operation and QC
Question | Answer |
---|---|
heating of the filament to the point that electrons boil off its surface | thermionic emission |
requires 4-6 amps of current | thermionic emission |
mA settings determine the amt of current that will be sent to the filament | thermionic emission |
high electrical potential applied to the cathode end of the x-ray tube | acceleration of electrons |
kV sent to the filament from the step up transformer | acceleration of electrons |
r-radiation is produced when high speed electrons bombard the target area or anode | acceleration of electrons |
the focusing cup surrounds the filament and maintains a concentrated stream of electrons from the filament to the target area on the anode | focusing of electrons |
made of molybdenum or nickel | focusing cup |
