X-ray power input and power output Confusion
I was looking at the power calculations of the X-ray machines and found something a bit unusual. As we know the input power must be equal to the output power. Considering an x-ray machine giving an ...

X-ray filament and cathode connection
I was studying how X-ray machines works. I have seen that the filament creates a current that produces electrons. By applying a high voltage between the cathode and anode, the electrons move towards ...

PWM generation for the transformer using SG3524N
I was looking at one of the schematics of the filament board of an x-ray machine, where they had used the SG3524N for the generation of PWM and MOSFETs for the generation of an alternating voltage for ...

Thermionic emission
I am doing the calculation for the "finding the temperature of filament".
I tried with:
Resistance (R=V/I)
Resistivity (ρ = R·L/A)
Temperature (T = (ρ-ρ0/ρ0-δ) + T0)
Here ρ0, δ and T0 are ...

Do neon signs emit x-rays?
I'm interested about whether or not a conventional neon sign such as this one could emit x-ray that could be harmful.
The sign that you can see in the picture is just below my office window so I'm ...

Would it be possible to power an X-Ray tube using a Marx generator?
To the best of my knowledge most X-Ray tubes are powered by a smaller voltage running through a large transformer to step it up into the magnitude of 10-100 KV. This larger voltage is then pulsed ...

Photodiode Direction Sensitivity
I'm trying to create a setup where I would have xrays emitted through a photodiode (the non sensitive side). I do not want the photodiode to detect these xrays going through it, only the xrays which ...

Might an x-ray tube have the capability produce more power than it consumes?
In transformers, when the voltage is powered up, the current is proportionally powered down.
In the x-ray tube’s transformer, this also happens.
However, the current of an x-ray tube is not the ...
