| + | Conclusion: the C02 percentage in the CDC has stabilized at about 52-53%. Curtis: we need to do measurements and then decide if we want to change the gas mixture. At some point we need to add also alcohol to the gas. | ||
| − | - | + | - Fernando: how stable the CO2 percentage should be. The way it works: one should correct for/calibrate the gas as often as possible. Naomi has simulated different gas mixtures. Also, one should correct for the pressure dependence - 1% pressure change results in 7% change of the amplitude. |
