transformer
Filament circuit - Answer-........
What is thermionic emission based on? - Answer-temperature of the filament
What is it measured in? - Answer-amperes
Filaments operate at how many amps and how many volts? - Answer-3-6 amps
6-12 volts
Voltage from the mA station is delivered to the ______________ transformer which is a
step _________ - Answer-filament
down
A lower voltage means a ___________ current to the filament - Answer-higher
What determines how many xrays are created? - Answer-number of electrons
number of electrons is determined by the temperature of the filament. the hotter the
filament the more electrons

allow a wide range of time intervals
mAs timers - Answer-electronic device
monitors the product of mA and exposure time
-mAs
mAs timers terminate the exposure when.... - Answer-mAs value is reached
Where is the mAs timer located? - Answer-on the secondary side of the high voltage
transformer
Why is the mAs timer designed? - Answer-to provide the highest mA for the shortest
exposure
Where are mAs timers used? - Answer-on falling load and capacitor discharge imaging
systems
AEC Control controls..... - Answer-time and not anything else
AEC measures.... - Answer-quantity of radiation reaching the IR
AEC automatically terminates when the IR has recieved.... - Answer-enough IR
exposure or desired film OD
What is the purpose of the backup? - Answer-to prevent over exposure if the AEC fails
