Task #20621
Update noise simulation for ProtoDUNE single phase
0%
Description
It would be great if we could update the noise simulation for ProtoDUNE single phase.
History
#1 Updated by David Adams about 2 years ago
The goal is to have noise level and frequency spectrum similar to that seen in the data.
The simulation uses ExponentionalNoiseSevice which has exponentially falling noise with a flat floor at high frequency. The data also flattens out at low frequency below 200 kHz.
The service has parameters for a low frequency rollover but when I change one of those, I see a sharp drop below the specified frequency.
I have modified the code so that a negative value for the rollover frequency give a flat spectrum below the magnitude of that value. I will now try to tune the params so sim matches data.

I have added a tune pdsp_chnoiseAug2018 to dunetpc/dune/DetSim/fcl/detsimmodules_dune.fcl. See my talk at the Sep 5 DRA meeting: https://indico.fnal.gov/event/18166.
The changes are pushed to dunetpc.

Tingjun:
Should we make this the default for protoDUNE simulation?

Hi David,
Do you expect things will change when the electrons are immersed in the liquid? I am OK with making this default now and update it later if there are changes.
Thanks,
Tingjun

I guess we will see tomorrrow. We can wait until then to make any changes. Thanks. --david
