Update diffusion constant #45

Closed JosephJHowlett closed 7 years ago

JosephJHowlett commented 7 years ago

The outcome of the long discussion here is that at least for now, we should be using 29.35 as the diffusion constant. The one chosen here comes from lax and @weiyuehuan's note, but doesn't reflect a multiplicative constant used to improve the fit to data.

I don't know if anyone have already used this config for fax simulation and see any discrepancy from data. We will be more confident making this change if someone did. If not, I will still suggest changing to 29.35, as it's the one we are now using in lax for real data.

Agree with @pdeperio that this should be checked before changing.

@jhowl01 Can you provide some plots of a comparative study?

Comparing fax-simulated and AmBe data:

fax_ambe_s2_width_comparison fax_ambe_s2_width_sliced_default_format

For better validation, I'm re-simulating in the full z-range and plan to compare with Rn220 data.
