- Preamp 4: Comparison of cosmic data with original preamp

Efficiency Plots for the CDC
The following plot is taken from our NIM article that shows the chamber efficiency as a function of the high voltage setting for various gas mixtures. As can be seen, for the optimal gas mixture (around 50/50), the plateau starts at about 2100 V and there is no efficiency below around 1900V.
