Signal to Noise Ratio


the S/N ratio should be 60:1 for the amplitude anode in a minimum ionizing event. We expect around 24,000 electrons in one anode assuming no charge sharing. The noise level is therefore 400 rms electrons for the total Hybrid.


Simulations show that the noise ratio quoted above, allows the position resolution not to degrade by more than 10%.
