Hi guys,

I need some help with my project.

Basically, to start off with I need to design a circuit capable of detecting alpha and beta particles from a prime detector.
The signal would then be amplified where the charge coupled amplifier would be used to turn the electrical charge to a voltage output with the shaping amplifier used to change the waveform of the signal for processing.
The discriminator would be used to seperate the alpha signal from the beta signal due to the fact that alpha particles are more energetic whereas beta particles have half the charge.
Below is a diagram illustrating what I just described.



I'm not sure where to start designing the circuit and what components that I need to use.

Any help would be greatly appreciated.

Thanks in advanced.

 

Let us begin with one block at a time.
Let us take the charge coupled amp. Why would you need two separate amps?

Wouldn't one of them be for the alpha signal path and the other for the beta signal as they have different energy levels?
Both signals eventually end up in the discriminator where beta signal would be pulled out from the alpha signal path.

Or would only one charge coupled amp be enough?

 

If the two amps are identical why the need to separate them?
The discriminator is what does the job of separating the two events.

 

I think you're right. One would be enough.

What would you recommend I do to build the charge coupled amplifier and the shaping amp?

 

Analog Devices AD8067. for the charge coupled amp.

TI LM6171 for the shaping amp.
